  Reading Glasses Computer Use



Reading glasses aren’t appropriate for computer use

It’s important to understand that reading glasses aren’t appropriate for computer use, as they are designed to help with different distances; most do not correct the intermediate zone at all. As opposed to computer eye glasses, Single vision reading glasses correct near vision only, and bifocals correct only near and far. Trifocals and progressive lenses [which are explained in other pages] correct only a small portion for the intermediate area, not nearly large enough for comfortable computer work.

Near-sighted or far-sighted glasses aren’t effective for the correct distance from the screen, which sits typically in the intermediate zone. Reading glasses are usually prescribed to read at a distance of 16"-18".

Computer eye glasses, however, will allow you to see the screen with clearer, sharper vision, because they eliminate the constant refocusing effort that your eyes go through when viewing the screen.

This may make a world of difference in your comfort level while you're using the computer: they can also relieve symptoms caused by your struggling to focus [such as eyestrain and burning] as well as correcting blurred vision.

The right computer eyeglasses will optimize your sense of ease and productivity at the computer screen, as computer eye glasses are usually designed to work at 18" to 28". You will be able to read and see out at some determined distance (approximately 10-13 feet).

A study conducted in 2004 by the University of Alabama showed that even if you aren’t aware of experiencing CVS symptoms, it’s still far more difficult to focus the eyes on pixels on the screen than it is to read printed material from a static page. It’s a very different kind of stimulus than any other kind of reading and you are probably losing productivity and accuracy without even noticing it.

An eye exam at your local eye doctor or a computer vision specialist can show whether you are actually reading at the quality and accuracy that you estimate privately.
