Causes of visual impairment and low vision aids
Low vision may be due to one or more eye conditions: macular degeneration, glaucoma and cataract are some of the most common, but visual impairment may also be caused by diabetes, high myopia, multiple sclerosis, retinitis pigmentosa or albinism. Children may be born with eye problems including glaucoma or macular dystrophies such as Stargardt’s.
There are many different types of low vision aids (LVAs) and one or more may be right for you. If you have macular problems you may benefit from magnifiers whereas other types of aids will help someone with glaucoma or retinitis pigmentosa. Cataract patients will appreciate protection from bright light and people with mobility problems may use a cane.
LVAs are generally available through low vision clinics and low vision specialists. LVAs include many different types of magnifiers available with varying amounts of magnification.
