There is life after vision loss.
What is vision loss?
Most of us experience normal
changes in vision as we age. These changes are physiological, can be corrected
with ordinary prescription spectacles or contact lenses and do not result in
functional limitations.
However pathological changes
in the eye can cause permanent irreversible loss of vision that cannot be
corrected in spite of conventional, surgical, medical and or optometric
therapy. People who fall into this category are said to have low vision.
Of all disabilities, low vision or partial sight is perhaps the most misunderstood. People tend to think of it as the “all or nothing “– either you are fully sighted or totally blind with no in-between. Very few people are in fact totally blind. Partial loss of vision or low vision is very much the rule rather than the exception.

remember that there is some form of vision remaining. The low vision
practitioner aims to find those areas of vision and make them function more
