Contrary to popular belief, doing these will not cause eye damage. Correct and useful lighting is extremely important to individuals with low vision. As well as the amount of light being important, the direction and focus of the light are important to reduce glare or shadows. High intensity lights with adjustable arms work well. Visors and hat brims can help block annoying overhead light.
Absorptive lenses are good for controlling glare.
After having a complete medical eye examination by an eye care specialist, a person should try to find a low vision clinic or eye specialist with training and background in low vision. Due to the complexity of many eye problems and the amount of time needed for a thorough clinical low vision evaluation there are not very many ophthalmologists or optometrists who specialize in low vision. A good low vision assessment usually involves at least 45 minutes from a doctor, and at least another 45 minutes from a trained vision rehabilitation therapist. Many times such appointments require more than 90 minutes total in order to determine any prescriptive device as well as other aids for near vision, distant vision, and what is best for the various environments a person is in.
