Visual Disabilities - Low Vision
- Challenges: Text in graphics does not enlarge without special software, and looks pixilated when enlarged
Solutions: Limit or eliminate text within graphics - Challenges: Users may set their own font and background colors
Solutions: Allow them to do so by using as much real text as possible, rather than text within graphics. - Challenges: Screen magnifiers reduce the usable window size
Solutions: To reduce that amount of horizontal scrolling, use relative rather than absolute units (e.g. use percentages for table widths instead of pixels)

Tips how to create website friendly for Low Vision users:- make the text large enough that low vision users could use screen magnifier easily;
- provide audio notifications to make users aware of the changes;
- minimize users memory load because the effective screen size is very small while using screen magnifier;
- enable users to locate information quickly;
- provide alternative CSS style sheets (with highly contrasting color scheme) additionally to the primary style sheet;
- provide whitespaces between links;
- provide helpful error messages;
- avoid using complicated and decorative fonts because they can be distinguished much harder, use standard fonts like Arial or Times New Roman that are ** more legible by the user.
