Double vision is the condition of seeing two copies of the same object, either next to each other or overlapping. When it appears in one single eye when tested alone, it is known as monocular double vision. When it happens only when both eyes are tested together, it's called a binocular double vision. Most of the surgeons featured at Trusted Lasik Surgeons™ have treated patients with a wide variety of causes for this condition, which in most monocular cases is caused by the eye focusing poorly on the light, and in binocular cases in the eyes not focusing together.
Double vision can literally be caused by any one of dozens of causes. Some of them are completely harmless, while others can endanger your life. Consequently, if you believe you are suffering from double vision, you should immediately see a qualified LASIK or Cataract Surgeon who can help determine the cause of your double vision.
Monocular double vision is generally the least dangerous of the two. Some of the most common causes are:
Monocular double vision is rarely caused by a life-threatening emergency.
Binocular double vision can be a different situation since it is caused when the two eyes become misaligned, which can be created by some life-threatening health problems. Some of the more common are strokes, aneurysms, head trauma, or brain tumors. Binocular double vision can also happen in patients with multiple sclerosis, migraines, myasthenia gravis, Graves' disease, diabetes, and high blood pressure. Sometimes binocular double vision can have completely harmless causes, such as fatigue or temporary illness. This is generally a temporary condition and it goes away when the underlying problem is resolved.
In most cases, treating double vision includes treating the underlying cause of the problem. Refractive errors can be corrected by eyeglasses or contact lenses, dry eyes are treated with artificial tears, corneal problems can be treated with medication or laser surgery, and cataracts are treated with the most common surgery in this country.
With binocular double vision, the condition can often serve as a warning sign to physicians to treat the underlying cause. Patients with diabetes, stroke, head trauma, and other neurological conditions often see double vision clearing up as the more serious cause is treated. Double vision caused by diabetes is generally resolved when the patient gets her blood sugar under control. Those with the condition caused by more minor reasons often respond well to treatment with glasses with prisms.
If you're experiencing double vision, it's crucial that you have it checked right away.
