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.


* 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.


* 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.
