Double vision, or seeing two of everything, may be caused by a number of factors such as refractive error, cataracts or a misalignment of the eyes. Having double vision can seriously disrupt a person's daily activities.
To understand diplopia, you must first understand that In normal vision, both eyes look at the same object. The images seen by the two eyes are fused into a single picture by the brain. If the eyes do not point at the same object, the image seen by each eye is different and cannot be fused. The result is double vision, or diplopia.
Eyes may appear misaligned or crossed, or wander. However, these symptoms may not apply to all cases.
Treatment of diplopia or double vision may consist of eye exercises to strengthen the ocular muscles, surgical straightening of the eye, or both treatments. A non-surgical approach is Eye Therapy, which may be prescribed to re-align the misaligned eye and re-stimulate the part of the visual pathway to the brain which is not working correctly.
