visually impaired : Java Glossary

You can design your websites to make them accessible to people with poor eyesight. For example, would want to avoid JavaScript animations, since some people work by screenscraping and using text to speech. In some way it is like designing for cellphones. You want narrow columns so that when the page is magnified a whole line still fits on screen.

There is a W3C (World Wide Web Consortium) standard called WCAG (Web Content Accessibility Guidelines) 2.0 that specifies what constitutes easy to read pages. You can use a program service at WebAim to test your pages.
