What is Prism

Prism correction is a type of lens correction that addresses a patient’s issues with double vision.

 Diplopia, or double vision, is caused when light interacts in a person’s two eyes in different ways. To create an image, light must come through the cornea and land on the back of our eyes, or the retinas. The brain processes light information that lands on both of our retinas to compose images, however, if light lands differently on the retina of each eye the brain has to process two different signals resulting in double vision.

Double vision is caused by a number of things including Eye-muscle problems such as myasthenia gravis, Grave’s disease, or strabismus (crossed or walled eyes), neurological issues like head injuries, strokes, or migraines, and nerve related issues like multiple sclerosis or diabetes mellitus.

Prism Correction Options

Prism Correction fixes this issue by bending the light before it enters the cornea so that it hits both retinas in an identical manner allowing the brain to process two complementary signals and to compose a single image.

Not all cases of double vision can be fixed by prism lenses depending on the cause. Double vision could be a symptom of a serious health condition. If you are experiencing new-onset double vision caused by eye misalignment or another unknown reason, consult a doctor immediately. 

Prism lenses for dive masks or other glasses are prescribed to remedy double vision the same way normal eyeglasses are prescribed. After undergoing tests, a patient’s lenses are measured and prescribed with a numerical unit of measurement called prism diopters. This unit alongside the placement and vertical, horizontal or diagonal alignment of a prism lens determine a patient’s prescription. This is to ensure the correct bend of light necessary to fix the patient’s double vision.
