Prismatic glasses, also known as prism glasses, are a type of eyewear designed to correct vision problems caused by misaligned eyes or double vision. They work by using prism lenses, which are specially shaped to bend the light entering the eye in a way that compensates for the misalignment. Prismatic glasses typically consist of a frame similar to regular glasses, but with lenses that have prism-shaped segments. These segments are made of a material with a different refractive index than the rest of the lens, which causes the light passing through them to bend at a different angle. By positioning the prisms in a certain way, the glasses can redirect the light entering the eye so that the images from both eyes are correctly aligned. Prismatic glasses can be prescribed for a variety of eye conditions, including strabismus (crossed eyes), amblyopia (lazy eye), and diplopia (double vision).
