What causes low vision?

Low vision is caused by a number of different medical problems, as well as by injuries to the eye such as might happen in an accident.

Some people with low vision have consistent, but poor, vision throughout their visual field, or "spots" of better and worse vision. Some have more of a problem with central vision or with peripheral vision. HumanWare products help across a range of conditions.

This Web site offers magnification of text (simply use the plus and minus keys on your keyboard) and several different colour combinations to help people with different kinds of vision problems use it successfully. See the top of every page in the site for the Colours pull-down menu and the "+ -" icon, which links to our Accessibility page.
