Yes you can add prism lenses to reading glasses. Adding a prism to reading glasses will require an eye exam with an optometrist first to determine the strength of the prism necessary for your condition. The optometrist will run certain tests based on the symptoms you present and what you may be experiencing with your vision. If you do need a prism added to your lenses, your prescription will have a number in the prism column. Prisms are added to reading glasses during the lens production process, however, if you only require a temporary prism, a stick-on prism may be placed on your glasses after they are made.

Prism eyeglasses lenses are special lenses used by individuals who have double vision (diplopia) or binocular vision issues. Double vision (diplopia) is an eye condition that causes individuals to see two images of the same object. Prism lenses help align the images by bending the light that enters the eye so that it is focused on the correct spot. Prism eyeglasses resemble regular prescription glasses. In some cases a temporary Fresnel prism in the form of a thin vinyl sticker is placed over the front or back of your glasses according to the American Academy of Ophthalmology.

The eye conditions that prism glasses correct are double vision (diplopia) and binocular vision issues. Double vision also known as diplopia is an eye condition that causes a person to either see two distinct images or two overlapping images of the same object. There are two types of diplopia, binocular diplopia and monocular diplopia. Binocular diplopia only occurs when both eyes are open and monocular diplopia occurs even when one eye is shut. Causes of double vision (diplopia) include cataracts and astigmatism, nerve-related problems that affect the eye muscles and brain-related conditions such as a stroke and an aneurysm. Binocular vision issues are when the eyes fail to work together properly or are misaligned as a result of an abnormal visual system, a stroke, brain injury or other neurological disorder. Symptoms of binocular vision issues can include eye pain, eye strain, blurry vision, light sensitivity, double vision and poor night vision. Other than prism glasses, vision therapy can also be used to treat binocular vision issues according to the Cleveland Clinic.

Prism glasses and reading glasses are not necessarily related, however, prism lenses can be prescribed to your reading glasses to correct your double vision or binocular vision issues. Reading glasses are defined as prescribed glasses designed to view objects and text at a near distance.

Prism is added to a prescription glasses’ lenses by making one of the lenses thicker than the other lens, which causes incoming light to bend in a certain way. Prism comes in different levels of strength depending on the extent of your condition, which can start from 0.5PD, 1.0PD, 1.5PD, 2.0PD and so on.

Yes, prism glasses can correct binocular vision dysfunction. Prism glasses aid binocular vision dysfunction by changing the direction of incoming light so it reaches the correct focal point on the retina. Binocular vision dysfunction (BVD) causes the eyes to misalign making it difficult for the eyes to send one distinctive image to the brain.

To get a prescription for prism lenses, you can book an appointment with an optometrist so they can examine your eyes and assess whether you require prism in your prescription. The optometrist will run different tests that help them to evaluate the health of different regions in the eye. You will know if you require a prism if there is a number in the prism column on your prescription and if you are experiencing double vision. If you already use prescription glasses, you can book an eye exam to see if your prescription needs updating.

Prisms work in glasses by bending the light correctly before it passes through the eye. Prism lenses are built with prisms infused into the lenses which enables the redirection of light so it reaches the retina at the correct focal point aligning the two separate images. Your prescription will decide if a vertical or horizontal prism is required and can extend up to 4.0 and 6.0 diopters. A prism is defined as a transparent or glass material that bends or refracts the light that passes through it as a result of the plane faces and angles of the prism shape.

Prism glasses are used for the correction of eye conditions such as double vision and binocular vision issues. Prism glasses are prescribed to patients with either double vision or binocular vision issues, which can help correct how the light that enters the eye is refracted. This will enable patients to see one clear image instead of two images of the same object.
