Mid-Range Vision Poses Problems For Many Computer Users.

Writing in the Wall Street Journal (8/17, D1) “Health Journal” on the front of the Personal Journal section, Melinda Beck points out that many people have difficulty seeing objects in the mid-range of their vision, particularly computer screens. Not only do those who wear glasses to correct either distance or close vision have difficulty, but also those who wear progressive lenses, too, unless they look at the screen exactly in the right spot. According to the American Optometric Association, approximately 40% of Americans spend three or more hours daily focusing on an electronic device with a screen. For some nearsighted middle-aged people, removing their distance glasses might be enough to help them read their computer screen for a while until they lose their close vision.
