If you have thought carefully about what lifestyle needs your glasses will have to accommodate and have purchased a durable set of frames, then you will probably only need to purchase a new set of eyeglasses when your prescription changes. Many people like to purchase a new set of glasses once or twice every 10 years or so simply to update their look. Scratch-resistant lens coating and shatter-resistant lenses are two product options that can easily extend the life of your glasses. Spring hinges are another good feature for improving the durability of your prescription eyeglasses.
If you don’t like the idea of regularly purchasing new eyeglass frames, avoid selecting very trendy eyewear. The hot fashion of today will become the fashion faux pas of tomorrow, and you may be stuck feeling behind the times while you wait for your look to come around again.
Another good way to avoid the trouble of having to buy eyeglasses later on is to buy two or more pairs now. When purchasing new eyewear, take advantage of the two-for-one specials that many frame dealers periodically offer. Your life, like that of most people, is multifaceted. A single pair of glasses may not be able to be both sporty and professional, but with two or more pairs of glasses to fulfill your optical needs, buying a new pair of glasses every couple of years won’t be necessary.
If you wear prescription eyeglasses, it is very important that you regularly schedule a complete eye examination. There are two main reasons for this. First, your prescription can change gradually overtime, decreasing your quality of vision almost imperceptibly. This means that having your eyes examined by an eye care specialist is the only way to ensure you are getting the maximum amount of vision correction out your glasses. Second, people with pre-existing eye conditions, even minor ones, often have a greater likelihood of developing more severe eye disorders. In their earliest stages, these eye diseases have few to no visible symptoms. Thus, if you wait until you think there may be something wrong, it may be too late to effectively treat the eye disease without losing some quality in your vision.
If your prescription has been stable for a number of years and you do not have a personal or family history of serious eye disorders, then you can probably get away with going to the eye doctor every other year. Children and seniors should get their eyes tested at least once a year because they are more vulnerable to eye problems than people in other age groups. Those who have been treated in the past for serious eye conditions such as glaucoma or cataracts need to be examined by a trained ophthalmologist at least once a year, and more frequently if a doctor recommends it. Persons with severe diabetes have a higher risk of developing diabetic retinopathy and other anterior eye problems. Diabetics should consult their primary physician about how often they should see an ophthalmologist.

Less Magnification or Minification of the Eyes
Also, the flatter aspheric lenses end up positioned closer to the face. This is a major benefit for anyone wearing a strong correction.
For strong farsightedness, aspheric lenses reduce magnification of the eye. The eye at left is seen through an aspheric lens. Through a conventional lens, the eye at right appears larger, even though the lens is the same power.
Strong farsighted lenses have a tendency to enlarge the wearer's eyes, producing an unattractive magnified look. Strong nearsighted lenses do just the opposite: they minify the wearer's eyes so they tend to look small and beady. Positioning a strong correction closer to the eyes lessens this magnification or minification, for a more attractive, natural look.
In minus lenses for nearsighted people, the front surface curves steepen away from the center and toward the lens edge. As a result of this gradual curve change, lenses end up with thinner edges. From an appearance standpoint, the thinnest possible edges for a strong nearsighted lens are produced when the aspheric lens is made of a high-index material.An even newer type of aspheric lens for strong nearsightedness has aspheric curves on the back side of the lens. This produces the thinnest possible edges for very strong minus prescriptions.

Buying Eyeglasses With Aspheric Lenses
Most popular lens designs can now be ordered in aspheric form, including bifocals, progressive addition lenses (no-line bifocals) and single vision. Some are made from high-index materials, too.
For several reasons, frame selection is important with aspheric lenses. In general, the best looking eyewear results when the frame is not overly large and when the eyes are centered in the middle of the frame opening. Your eye doctor or optician will guide you in selecting the best type of frame to use with your new aspheric lenses.
Taking measurements for aspheric lenses requires greater care and skill on the part of the optician, but this only requires an extra minute or two. Creating the complicated curves used in aspheric lenses makes them a little more expensive than conventional lenses. But the outstanding cosmetic and visual benefits of these marvelous lenses make them a good investment.
Since aspheric lenses are flatter and positioned slightly closer to the face than conventional lenses, some wearers may notice more reflections off the flatter back surface of the lenses. The best way to eliminate these reflections is to order an anti-reflective coating, which also improves vision through the lenses.

Bifocal glasses
Bifocal glasses are used to correct vision at two distances—a prescription on top for far away and a different prescription on the bottom for near. Most people think of bifocals as reading glasses for people over forty who lose their ability to focus up close as they age. But children can also need reading glasses.
Many children have not developed sufficient control over their focusing systems, the natural lens inside the eye that keeps images clear, especially up close. Some children lack the ability to sustain sufficient focusing over an extended time period, so after a while print begins to blur. Others can’t make fast focusing shifts from one distance to another, like from the board to their desks, so any time they look away, everything is blurry. Some children have a tendency to over focus, and the additional stress causes eyestrain and headaches. If they over focus too much, the additional tension on the visual system can make the eyes to turn too far inward, causing double vision. Finally, near work at school places much more stress on the visual system than distance viewing, and some young children respond by translating the visual stress into physical and emotional symptoms—back and neck tension, headaches, constriction of their perceptual fields and a reduction in their visual space, a tendency to develop nearsightedness, and avoidance of the reading tasks that are causing the physical and visual discomfort.
Prescribing reading glasses effectively treats many of these problems. A convex plus lens relaxes the child’s focusing system, relieving much of the visual stress. In fact, prescribing a low power plus lens is so effective in keeping children’s visual system comfortable during extended close work at school that they are often called “learning lenses.”
Reading glasses that use a bifocal are a good option for school-aged children who only need the additional correction up close. The bifocal gives them the lens support they need for deskwork but doesn’t change their distance vision. Sometimes vision therapy is also prescribed when the focusing problem is severe enough that additional interventions are also required.
New advances in lenses allow children flexibility in the type of bifocal they choose. Many children still prefer the flat-top bifocal because the line separating the two powers helps them tell exactly where their distance prescription ends and their near prescription starts. However, some children or parents don't like the look of the "line", so for them progressive no-line bifocals are a good option. The lens is made so that the change between prescriptions is so gradual no line appears. Another very popular option is the "half-moon" bifocal. It has the advantage of a clear delineation between powers liked lined bifocals but when the glasses are on the child's face, the bifocal is invisible like progressive lenses.
When bifocals or reading glasses are prescribed, it is important that children wear them for all close work, especially at school and during homework. Sometimes children will only need the bifocals for a few years as they develop control of their focusing system. Others may need the additional near-point support for as long as they are in school and spending a lot of time reading.
Bifocals are an important tool for optometrists when working with children who spend up to eight hours a day using their eyes for reading and school work. By adding an additional lens power for up close, optometrists are able to adjust children’s focusing system to give them better control and eliminate eyestrain, blurred vision, headaches, and fatigue.

Transitions bifocals
Q: I had a patient come in today asking for transitions lenses. He wanted the distance to be photochromic, but the seg he wanted to remain clear.
I was curious as to if such a lens was possible with what little I know of the technology, and if it was, does it exist?
A1: The patient probablly had a glass Photo gray ST 28, probably wants same again, but doesn't know the difference between transitions and photo gray. Glass photo gray ST 28's have clear segs.
As to transitions made this way, I don't think there are any available, but since transtions is a dip, lens could be masked in segment area before dipping.
By: chip anderson
A2: segs on glass lenses are not photochromic, not very appealing, cosmeticly. The seg is a different RI from the rest of the lens that was cast from silver halide laden molten glass. This seg "button" is attached and becomes part of the glass lens in a very interesting process. If you ever have a chance to see glass lenses, especially segmented products being produced at a factory, it is worth seeing.
It is still hard for me to understand why anyone would want that type of look....clear or dark segs and all, with all the great PALS out there, why would anyone want a seg line! I just hit 50 and have had to wear glasses for about 3 years now. The folks I grew up with all hit that age where their arms became to short. I am happy to say only one person among my peers bought bifocals....but his next pair will be a PAL, now that he knows that they exist. His ECP never presented the option to him. Beat that.
I do want to clear up one misconception in the prior posting.
Transitions are not produced by dip coating. Transitions Lenses are produced by placing the photochromic package into the front surface of the lens (imbibition technology) or by bonding a photochromic layer (Transbonding) on Trivex, Polycarbonate and 1.67 Hi Index lens materials.
Both Transitions Lens processes are patent protected.
Thus leaving the dip coating (photochromics disolved in a liquid carrier, lens dipped in the solution, allowed to dry then heated to permenantly place the pc chemicals on the surface of the lens) along with cast in place (photochromic package mixed with monomer (just like glass pc process) and cast in desired lens mold design) as the other options to make a lens photochromic.

Bifocals for kids
Executive-style lenses for children are overkill. For one thing, these lenses are often prescribed to reduce accommodative esotropia, which often occurs in highly hyperopic children (who need a high plus power). These lenses are excessively thick, heavy, and limited in material availability.
A FT-35 should provide more than enough width for a child (I can't imagine a child turning his/her gaze out that far to read anything -- it's almost a 40-degree eye rotation). Also, a FT will leave a little temporal vision for seeing the ground in the periphery more easily. It should be pretty easy to get a FT-35 in several materials, including polycarbonate.
As far as progressives for children... I would be tempted to use a short-corridor progressive, myself (and only if cosmetics are a serious issue). Most children wearing bifocals do so because of binocular vision disorders, not because of reduced accommodative amplitudes. This means that children can often see clearly anywhere through the distance, corridor, or near zone of the lens. However, if the child doesn't reach the full power of the near zone the benefits of the lens are not realized. This is exactly why bifocals are positioned so high with children. Progressive lenses, which already require more depression of the eyes while reading, must be positioned several millimeters above the pupil on children. You should also be aware of reduced distance and near utility.
On the other hand, certain "computer" lenses might show more promise for children. I believe there was actually a study conducted to evaluate such lenses for children, although I do not have the results handy. Blended bifocals, fit high, might also be an affordable option.

TIPS ON FITTING BIFOCALS TO CHILDERN
Try fitting E style or large round seg bifocal with segment tops just 1mm below pupil,reason for this high fitting is to ensure that the child does not use upper portion of the lens for close work,and in the event if his/her spectacles get loose.Also use specially designed spectacle frames for very small childern which have loop-end sides thru which a ribbon can be passed and tied at the back of the head to secure spectacles.With hyperactive small childern use frames fitted with bridle.For older childern frames with curl ends serves the purpose well.
If the child does not accept glasses, try experimenting with different positioning of segment tops, keeping in mind that he is required not to look from distance portion of segment for close work.

how to repair scratched glasses lenses
Wearing glasses isn't as popular as it once was since more and more people who need vision correction are choosing contact lens instead. If you have glass eyeglass lenses, they're better than plastic lenses because glass doesn't scratch as easy. However, glass lenses still manage to get scratched. And, it's hard to see through scratched lenses, no matter what the material is.
You might think that the only way to get rid of the scratches is to spend the money for a whole new set of eyeglasses. You can do it this way, or, you can just purchase replacement lenses and reuse your existing frame. Or, as long as your eyeglass prescription is current, you can save even more money by simply repairing the scratched glasses lenses yourself.
How can you do this? There are good quality polishing kits on the market that you can purchase for this purpose. A kit will cost anywhere from ten to twenty dollars, and it works best when it's used for lighter scratches. Lighter scratches are generally acquired from day to day wear. They also are made on the lenses of your glasses if you use a paper towel, or another type of rough cloth or material to clean them with. Whether you have plastic or glass lenses, you should also use a clean, soft towel and a recommended lens cleaner.
Deep scratches are usually caused by rough handling of the glasses, or, by accidents. They cannot be polished out like lighter scratches can. If you have deep scratches in your glasses, then you'll have to visit your local optometrist to see what he or she recommends. Again, replacement lenses will probably be your only option if your glasses lenses have deep scratches on them.
You can check with your local optometrist to find out what type of polishing kit he or she might sell. Or, you can perform a search on the Internet to find out what other kits are available online and the price of each one.
Once you purchase a polishing kit, be sure that you read the manufacturer's directions and follow them in order to achieve the best results. Some polishes won't work if your eyeglasses have a protective coating or a non-glare solution on them.
Basically, though, all you need to do is to make sure that the lenses in your eyeglasses are clean. Then, pour some of the polish onto both sides of each lens. Allow the polish to sit for a specified number of minutes. Then, use the cloth that was included in the kit to buff the lens until all of the polish is removed. The glass should now look clean, clear, and free of lighter scratches!
Usually, you can use a polishing kit as much as you need to in order to keep your glasses lenses free from scratches from then on. Never more will you have to squint to see through scratched glasses!
Finally, in order to best protect your health as well as your vision, you should have your eyes checked by a licensed optometrist every year or two. And, take care of your glasses so you can avoid replacing them before they are due!

How to Polish Scratches Off Glasses
Nothing is more frustrating than getting a new pair of glasses only to find that somehow you have gotten them scratched. Eyeglasses are a large investment and many times need to be kept for years. Finding that a scratch is now permanently in your line of vision, you may be tempted to toss them out, but before you give up, try these steps to remove the scratches from your eyeglasses. Read on to learn more.
Step1
Understand the limits of removing scratches. Unlike other glass or crystal products, buffing will change the strength of the lenses. Deep scratches can be cleaned up but not removed completely and it's possible that minor scratches can become unnoticeable.
Step2
Know exactly what your surface is made of. Check if the surface Is glass or plastic lenses with or without coating. This will make a difference on the approach you take to remove scratches.
Step3
Use a lens cleaner, either from your optometrist or from a CD cleaning kit. This works best to remove minor scratches on eyeglasses.
Step4
Try a metal polish and a soft cloth, rubbing in a circular pattern for about 5 minutes, depending on the severity of the scratches. It may take several applications, so continue to polish until you achieve the results you desire. Rinse the glasses in soapy water to remove any residue when finished.
Step5
Rub on creams made for taking scratches from sports helmets. You can find the cream in most sporting goods stores.
Step6
Drop a small amount of baby oil onto the lenses and rub with a soft cloth. Again, this may take time and works best for minor scratches.

Reading Glasses, Contact Lenses and Eye Glasses
Reading glasses come in two main styles: full frames, and half-eyes, the smaller
Franklin glasses that sit lower down on the nose. Many people feel they look better
in contact lenses rather than eyeglasses. Reading glasses are suitable for people
who spend a great deal of time concentrating on material close-up. Contacts lenses
are a safe and effective alternative to eyeglasses when used with care and proper
supervision.
The need for reading glasses has long been associated with being old. Have you
found yourself having to push that magazine out at arm's length to see the fine
print? You've officially reached middle age. However contact lenses, when compared
with eyeglasses, require a longer initial examination, more follow-up visits to
maintain eye health, and more time for lens care.
Reading glasses can be custom-made for each individual through an optical
dispenser, or they can be purchased "ready-made" at the pharmacy or department
store. Contact lenses move with your eye, allow a natural field of view, have no
frames to obstruct your vision, and greatly reduce distortions. They do not fog up,
like eyeglasses, nor does mud or rain splatter them.
Reading glasses are safe in that they cannot damage the eyes physically, whether or
not they are the optimal strength, or whether they are used correctly or incorrectly.
Contact lenses, compared to eyeglasses, generally offer better sight.
Reading glasses, containing low power plus sphere lenses, and are widely available
for non-prescription, over-the-counter purchase. Most eye-care professionals
recommend replacing your contact lenses case every 3 months for optimum eye
health.

Safety Reading Glasses
Safety reading glasses, are not a brand-new product, they have been out for about four or five years now, but there are still a lot of people that have never heard about them, so that's why we're going to talk about them today.
When these things first came out there was only one company that had them available,
and I was a distributor for that company, so I was doing pretty good with them on eBay, but as it is with everything in the eyewear industry once something new starts to catch on, other manufacturers get involved, so now here we are several years later and I couldn't even begin to tell you how many companies are now making safety reading glasses.
Needless to say the eBay market is flooded now so I'm not selling as many on eBay as I used to.
But they are still one of my hottest selling items on my web site and off my mobile truck.
These safety readers really are the greatest thing since sliced bread when it comes to a safety or industrial environment!
Why is that? You might ask, here is why.
Many of you, myself included, that have been wearing prescription eyewear whether regular or safety glasses for any length of time have it in our train of thought to go to the doctor periodically and get an eye exam, we wear glasses so our mindset is such that we know from time to time we have to go and get an updated prescription.
But as I'm sure you're aware of, the times we live in now and this generation is full of baby boomers,
we have more middle-aged people now from 40 to 65 than ever before in the work force.
And although a large number of these people have never needed glasses in the past,
As they get older they need some help reading.
So what do they do?…They go to the nearest Walgreen’s Drugstore, or Rite Aid or what ever Drug store is in their area and buy themselves a pair of Cheaters, or off the shelf
Reading glasses.
A.Because it does not require a prescription
B.Going to the Dr. for an eye exam is not in their train of thought
C.It is convenient, and they are there anyway
And for the most part that is OK for people to do.
But, what makes it bad is, if you are working some place where safety glasses are needed
What happens is, (I see this all the time in my job) people will wear the safety glasses
That the company provides for them for free, then they carry their drug store Cheaters in their pocket, and when they need to see close up or read something they take off the safety glasses, and reach in their pocket and put on the cheaters.
Well what’s wrong with that Mr. Mobile Eye Guy?
Think about it……those drug store cheaters are not safety glasses, and they are not Z87 OSHA compliant, so every time you take off your safety glasses to put on your cheaters
YOU ARE AT RISK for an injury! Why take the chance with your eyes?
That is why everybody in a work environment loves these things, and more and more people are starting to look for them.
You don’t have to carry around an extra pair of glasses, you can just put your Safety Reading Glasses on and leave them on all day, then:

Clear Readers Reading Glasses With an Invisible Presence
When faced with the reality of having to wear reading glasses some people will try anything to avoid them. There is another option that allows you to wear reading glasses, but keep it low key so others may not even notice you have them on. Clear plastic reading glasses have an invisible look to them. For those not happy with the idea of wearing reading glasses this may be their answer.
The idea of plastic frames can turn some people off. In the past plastic frames were quite heavy as compared to metal frames. However, the technology today has allowed for the creation of lightweight plastics, like zyl or TR-90 memory flex plastic. TR-90 memory plastic also offers an added benefit of being flexible that makes frames much more durable. Memory plastics have the ability to form to the wearers face to provide a comfortable, custom fit with every wear. Clear plastic reading glasses do not have to be avoided simply because they are plastic. Just look for the special materials available that make them very comfortable to wear.
Clear plastic reading glasses offer a clear frame as the name suggests. The plastic frames are good for stronger prescriptions because they offer more coverage for the edges of these thicker lenses. To ensure a light feel
combine the lightweight plastic material frames with lightweight lenses available from your doctor. Clear plastic reading glasses are available in full size or half size as well as many different styles. The invisible allure of clear plastic reading glasses is what keeps them a popular choice for new wearers.
Choosing reading glasses can be difficult especially when you do not want them in the first place. Clear plastic reading glasses offer a lightweight, invisible option for people not wanting to draw attention to the fact that they are wearing them.

Reading Glasses
If you're over age 40, you'll probably need to wear reading glasses to see clearly up close after LASIK. This is due to presbyopia, which is a normal age-related loss in near focusing ability.
Though you should continue to have routine eye exams after LASIK to have the health of your eyes checked, it's not necessary to purchase expensive custom-made reading glasses. Pre-made "over-the-counter" reading glasses, available either online or in specialty stores, are usually just as comfortable and cost less.
Since pre-made reading glasses (commonly called "readers" or "cheaters") are relatively inexpensive, you can afford to buy several pairs. It's highly recommended that you have more than one pair of reading glasses. Leave a pair at work, keep a pair in your car, and have a few pair at home so you don't have to go searching for your readers every time you want to see something up close.
The power of reading glasses usually ranges from +1.00 to +3.00 diopters (D):
* Low-power readers (+1.00 or +1.25 D) are usually the most comfortable for computer use, reading a newspaper, or doing other visual tasks at arm's length.
* Moderate-power reading glasses (+1.50 to +2.00 D) are usually best for seeing things a bit closer (e.g. reading a paperback book or reading in bed).
* High-power readers (+2.25 to +3.00 D) are usually best for fine detail tasks (e.g. manicuring your nails, threading a needle, or tying a lure on your fishing line).
For most people, +1.50 reading glasses are the most versatile. You may want to try these first. If they seem too strong for certain visual tasks, buy at least one pair of low-power readers as well. If the +1.50 readers don't seem strong enough for some tasks, purchase one or more pair of higher power reading glasses for more magnification.
Be aware that higher power reading glasses will provide more magnification than low power readers, but they also require a shorter working distance: You'll be able to see small details better, but you'll have to hold objects closer to your face for the details to be in focus.
Wearing reading glasses that seem to be the wrong power won't harm your eyes in any way---you just won't see as clearly!

Reading Glasses Guide to Strength and Fit
by: speclaces
If you are having trouble focusing on reading material or other objects 12 to 14 inches away, non-prescription reading glasses may be the solution. They are manufactured in an unending variety of shapes, colors, styles, fabrications, and prices. You can even find non-prescription UV-protected bifocal sunglasses for reading in the sun. Bifocal Sunglasses
CAUTION. If you've never worn over-the-counter readers, I strongly recommend that you talk to an optician or ophthalmologist before you buy your first pair. Although millions of people wear them successfully, readers aren’t for everyone. For example, if you have astigmatism or uneven eyes (different vision in each eye), non-prescription reading glasses may cause a headache or dizziness when used for any length of time.
LENS STRENGTH
* The strength of over-the-counter reading glasses is measured in diopters, also referred to as powers or strengths.
* Non-prescription readers are generally available in the +1.00 to +3.00 range in 1/4 increments. Higher strengths are available on a more limited basis.
* Make sure you buy aspheric lenses; Otherwise you may experience dizziness or headaches. Aspheric lenses are ground so that there is no distortion or wavy vision.
FRAME FIT
* Although most users know the strength they need, very few people know the measurements of their frames and rely instead on how they look and feel.The width of the frame across the front from temple to temple is probably the main consideration.
* You’ll find that the majority of reading glasses on eBay measure between 5-1/2 and 4-3/4 inches wide.
* If you don’t know what width you want and don’t have an existing pair to measure, here’s a little guidance. If, for example, you have a larger head and prefer a wide frame, look for frames that measure at least 5-1/4 inches Don't worry about identifying an exact width you can wear. Spring hinges provide flexibility and comfort so you can wear a variety of frame widths. Just be sure that the frame you choose has spring hinges.

Hide Your Need For Reading Correction With No Line Bifocal Reading Glasses
by: Steve Cogger
The mention of bifocal glasses can cause one to build a mental picture of an old person, possibly Grandma or Grandpa. The idea that you need bifocals may seem damaging to your ego - you might feel like you are getting old and everyone will notice. This is just not true anymore. New innovations in lenses have produced a new no-line bifocal.
Reading glasses often become a must for those over forty due to a natural condition called presbyopia. Presbyopia is a hardening of the eyes lens that decreases its flexibility, causing problems with nearsightedness. People who do not wear glasses for other vision issues will correct the problem by buying a pair of reading glasses. If you wear glasses normally your doctor will suggest adding a bifocal to your normal lens. Bifocal lenses have a small section of the lens made in a different prescription specifically for your reading needs. The older style of bifocal lenses had a visible line separating the two prescriptions. New no-line bifocals offer a solid lens with no visible distinction between the two prescriptions. Discreetly adding a bifocal to your regular eyeglasses is easy and undetectable with no-line bifocals.
The use of a bifocal lens can really be helpful as reading glasses. People add bifocals to their regular glasses to aid in reading, but for some people who do not normally wear glasses a bifocal lens may still be the answer. Full size reading glasses with a no line bifocal added to a non-prescription lens are a good choice for someone who has to see close-up and at a distance often. Reading glasses with no line bifocals help to reduce the fatigue of taking reading glasses on and off repetitively. They are also a plus for the person who doesn't like the look of half size reading glasses, but still desires the convenience of being able to go from near to far easily.
The option of no line bifocal reading glasses is helpful for those who wear glasses for other vision issues as well as for those who do not usually wear glasses. The invisible line allows for a more natural line of vision and transition between reading and distance vision. No line bifocal reading glasses may be the answer you are looking for when reading starts to become difficult.

Eye Strain Got You Down? Simple Steps To Reduce Computer Vision Syndrome
Have you ever wondered why long hours in front of the computer leave your eyes feeling tired and strained? What is it about computer monitors that leave us feeling tense, blurred, and dry in the eyes?
Focusing up close for any long period of time has temporary effects on our eyes. For starters, when we focus up close, our blink rate slows down. The average person blinks about 20 times every minute during normal activity. Blink rates slow down to less than half that when we are focused intently on anything up close, this includes the computer screen.
But why do computer screens affect our eyes more than reading a book or the newspaper? Computer images are pixilated, meaning they do not have sharp edges. In turn our eyes are working a little harder to make out the edges and convert these pixilated images to sharp edges. Printed material, such as text in books, has sharp edges. To reduce the pixilated effect on your computer, you can increase the screen resolution; however, this tends to shrink the size of the text you are viewing.
Another aspect that affects our eyes while working on the computer is the monitor location. Having the monitor ergonomically located below eye level will make your eyes feel better. The eyes dry through many means, including evaporation. If you are constantly looking upward at the monitor, your eyes will be more open lending them to more evaporative dry eye symptoms. Keeping the monitor located at a lower level will keep your eyes more closed while working, trapping in moisture.
An easy fix for your computer strained eyes are a pair of computer vision eyeglasses. Glasses will aid in ocular relaxation and allow you to work longer and more comfortably on your computer. Computer glasses are essentially low power reading glasses that simply magnify the screen. If you do not regularly wear reading glasses, simply get a pair of +1.00 readers and feel the re-empowerment of being able to work at your computer eye-strain free.
Suzanne Hughes welcomes you to view the wide selection of computer and reading glasses that are sure to make you and your eyes more comfortable.
