Double Vision

Seeing mirror images either horizontally or vertically, when focusing on a targeted object.

Sometimes referred to as “diplopia,” double vision is the perception of mirror images and is often a sign of larger problems that stem from complications with the cornea, lens, and nerves of the eye, as well as the muscles that cause movement of the eye and lid.

How Double Vision Impacts Vision

Double vision may cause a sufferer to see dual images when focusing on a targeted object – either horizontally or vertically. It may also lead to droopy eyelids and cause a sharp pain when moving eyes in either direction. There are two types of double vision: binocular (“cross-eyed”), and monocular (double vision in only one of the eyes).

Double Vision Causes

The misalignment of both eyes is what causes double vision. Corneal infections, cataracts, myasthenia (an autoimmune disease), unchecked diabetes, migraines, strokes, and aneurysm are among the most common causes and indicators of double vision.
