Eye doctors usually recommend prism glasses to patients who struggle with double vision, blurred vision, headaches, or other symptoms caused by slight eye misalignment. Prism correction helps correct eye alignment so that you only see one clear image. The prism added to your glasses bends light before it reaches your eye. The light is then redirected to the proper place on the retina of each eye. In effect, your brain fuses the two images to create one clear image. 

Why You Might Benefit From Prism Correction

Diplopia could be caused by several things. A prism isn't always the solution for all cases of double vision. Since this vision problem could be a symptom of a severe health condition, you must consult your eye doctor to determine what exactly is causing it. 

In many cases, double vision occurs due to eye misalignment. Prism glasses may help fix your double vision if the misalignment is caused by eye muscle problems like strabismus or nerve-related concerns like diabetes mellitus. Prism correction may also work for you if your diplopia is due to a neurological or brain-related problem, such as a migraine, head injury, or stroke.

Before experts understood the connection between the eyes and the brain, eye doctors would enhance their patients' visual comfort by adding a small number of prisms to their prescription eyeglasses. But a pair of standard prism glasses can only address eye misalignment at a single distance. Neurolenses, on the other hand, can resolve misalignment issues at all distances. This cutting-edge technology uses a contoured prism to slowly increase the prism from distance to near. This helps provide proper alignment at all points. As a result, Neurolenses align your eyes, alleviating the symptoms associated with trigeminal dysphoria.

Understanding Trigeminal Dysphoria

Trigeminal dysphoria is an umbrella term that doctors use to describe common eye-related problems people experience today. This is especially true for those who use digital devices for hours on end. The symptoms mentioned above aren't new. In fact, trigeminal dysphoria has been referred to in the past using many other names including fixation disparity or convergence insufficiency, among others. In a nutshell, binocular eye misalignment characterizes this eye condition.

When your eyes are misaligned or out of sync, it adds more pressure on your visual system. The increased demand causes stress on your trigeminal nerve, which is located in your head and neck. It's the most complex cranial nerve connected to your brain. Your trigeminal nerve plays a huge role in your head and neck sensations. With the higher demand on your visual system during digital screen use, the incidence of trigeminal dysphoria symptoms also increases.
