The Low Vision Center has many non-optical aids available for visually impaired people to try. As we age, a person age 65 or older probably needs 15 times as much light to read as does a year-old.
And importantly, a person with low vision may need three times as much light to read as a person their age who does not have a vision loss. Therefore, flexible-arm desk or floor task lamps are perhaps the most helpful and important non-optical devices for many people.
A flexible-arm desk lamp Some advantages of flexible-arm task lamps are: They are obtained easily at a non optical aids for low vision of stores, catalogs, or online. They can be relatively inexpensive.
They can be adjusted to a variety of settings and tasks.

Reading a label with flexible-arm desk lamp There are many types of lamps: Try different lamps to see what you prefer. Try to choose one that is a low "Kelvin" rating — under 5, Kelvin K — so that it does not emit ultraviolet or blue light.
Optical and nonoptical aids for reading and writing in individuals with acquired low vision.
Perhaps even more important than the type of non optical aids for low vision is the position of the light—particularly the distance from the lamp to the task you are doing or to your eye.
Bring the lamp closer to help maximize the light delivered to the task and your eye. Reading Stands Reading stands can help with both reading and writing, by allowing you to position your reading and writing materials more effectively.

One type of reading stand Some advantages of reading stands are: They bring reading and writing materials closer to your eye, thus helping to achieve "relative distance" magnification: Non optical aids for low vision help you see a wider field of view, or more lines and text at a time, because the image is closer to your eye.
They allow better illumination, because you are not as bent over, which can block out the reading light.
They provide better posture and ergonomics, which leads to less fatigue and strain on your neck and back. Absorptive Sunglasses Glare is a major problem and concern for many persons with low vision.
Absorptive sunglasses help filter out bothersome glare and harmful light rays. Most sunglasses now block out ultraviolet light.
