How a Low Vision Reader Works
Low vision readers, also known as microscopics or prism spectacles, are designed to help with reading for patients with central scotomas. To help these patients read, they need everything made bigger. By magnifying everything around the scotoma, the scotoma’s effect is reduced.
There are many products that magnify – CCTV’s, hand-held magnifiers, and telescopes. Each of these devices has its own particular benefits. A low vision reader is useful in that it’s portable, affordable, and can be worn on the head, freeing up both hands.
What Does the Prism in Prism Spectacles Do?
When wearing glasses to make the reading material bigger, the reading material needs to be brought closer to the face in order to focus. A +10.00 needs to be about 4″ from the face to be in focus. If you try to focus on something at 4″ with both eyes, your eyes get tired very quickly. Base-in prism reduces the eye strain associated with focusing at a close distance.
