Legal Blindness
Legal blindness is a level of visual impairment that has been defined by law to determine eligibility for benefits. The definition includes a central visual acuity of 20/200 or worse in the better eye with the best possible correction, as measured on a Snellen Vision Chart or or a visual field of 20 degrees or less.

Low Vision
Low Vision occurs when the vision loss is severe enough to impede a person’s ability to carry on every day activities, but still has some useful remaining sight. It cannot be cured, but with the help of low vision devices, people can benefit from a variety of available optical devices. These could include such items as electronic magnification devices, eye-glass mounted telescopes, hand-held magnifiers and distance devices. Special software for computer users is available that enlarges text or reads the text aloud. Braille software is also available.
