![]() The result is the production of two images. With double vision, light entering each eye falls on different spots on the retina, making it so your brain can’t process the visual information accurately to create a single clear image. Your brain combines this visual information from each eye to produce a single clear image. Each eye collects visual information that’s sent to your brain for processing. Light hits the same spot of the retina in each eye. Your eyes work in tandem to enable your brain to visualize a single image. When your vision is clear and you have normal binocular sight, light enters each eye through the cornea and falls on the retina. They may be base in, base out, base up, or base down, depending on the direction of the eye misalignment. Prism eyeglasses help your eyes discern images so that single vision results in correction of binocular vision, double vision, reading difficulties, vision-related headaches and more. They do not contain any focusing ability and are ineffective at correcting refractive errors. ![]() They change the direction where light is reflected, directing it to the correct place on the retina.

Who needs prism glasses?īinocular double vision (using both eyes) usually occurs when the muscles around the eye, which move your eyes up, down, left and right, don’t work properly. Sometimes, people who have blurred vision have diplopia, as the images they see are only slightly separated – resulting in ‘fuzziness’.
