Prism lenses can be effectively used to treat vision conditions, such as double vision and other binocular vision difficulties.
One of the most common uses for an eye doctor prescribing prisms is to treat a condition known as Binocular Visual Dysfunction (BVD).
Prisms, by definition, are triangular in shape, and made of plastic or glass for the purpose of dispersing light into a spectrum, or changing the direction in which light is reflected.
Prism lenses are special lenses that are prescribed by eye doctors and infused into regular lens prescriptions. They do not contain any focusing power, and therefore cannot correct any refractive errors.
Prisms “trick” the eye into believing that an object is in a different location in order to improve eye alignment. This helps the eyes to perceive images in a way that single vision can be achieved— improving binocular vision, and reducing double vision, headaches, reading difficulties, and more.
A prism lens can be base out, base in, base up, or base down, depending on the way the eye is turned or misaligned.

Are prism lenses a long term solution?
While prism lenses will help to relieve double vision while you are wearing your glasses, they cannot help your double vision when you remove your glasses. Therefore, prisms may only be a temporary solution.
If you are searching for a long term solution for your double vision or binocular vision difficulties, speak with your doctor about vision therapy.
Vision therapy retrains your eye-brain connections to improve your visual skills for clearer, single vision, with or without your eyeglasses.
If you suffer from double vision or binocular vision difficulties, prism lenses can be prescribed to improve your clarity of vision— enabling a more comfortable way of seeing.
