What is low vision?

Someone with between 20/70 and 20/200 visual acuity is considered partially sighted and with better than 20-degree restriction field of vision or 20/200 vision is legally blind.

While low vision cannot be corrected, there are visual aids available that can help to improve your sight. More commonly used optical devices include telescopic glasses, light-filtering lenses, magnifying glasses or hand magnifiers, and reading prisms. For many, reading software, talking watches, cellphone apps, and large print publications can make all the difference in their independence.

On occasion, those diagnosed with retinitis pigmentosa – an inherited retinal disease that causes progressive loss of night and peripheral vision and can lead to legal and complete blindness – can be fitted with a retinal prosthesis that will partially restore their sight—allowing them to live independently and improve navigation.

If you notice that vision difficulties are preventing you from performing your regular activities – reading, driving, recognizing faces, ability to tell colors apart, and seeing the television screen – contact your eye care specialist. During a dilated eye exam, specialists will use lighting, magnifiers, and special charts to assess visual acuity, depth perception, and visual field to determine if low vision-causing conditions result in vision difficulties or if it is something that can be treated or corrected.
