Most of us take for granted that when we open our eyes in the morning, we see single, clear images. If you are experiencing blurred or double vision, it’s time to visit your physician. Diplopia, more commonly known as double vision, can be a warning sign for cataracts.
Cataracts are cloudy areas in the lens of the eye. In a clear lens, light can pass through to the back of the eye so you can see well-defined images. If your lens is cloudy, light cannot pass through the lens as easily and images are blurry and less defined. Images may also seem fuzzy or filmy, and you may experience intense glare from light sources. You may find that reading a book, driving and differentiating facial expressions is increasingly difficult (Source: Medicalnewstoday.com).
Not all double vision is necessarily due to cataracts. Lack of sleep or drinking too much alcohol can also cause double vision, but it will only be temporary. Chronic double vision is a serious condition and should be treated right away. Besides cataracts, other causes for double vision include:
- Cornea problems due to infection, scarring or dryness.
- Nerve problems such as Multiple Sclerosisis, Guillian-Barre syndrome and diabetes.
- Brain problems due to strokes, aneurysms, or tumors.
- Muscle problems due to conditions such as Graves disease or myasthenia gravis (Source: WebMD).
If your physician determines that your double vision is due to cataracts, the good news is that cataract surgery is a simple outpatient procedure. Your surgeon will remove the cloudy lens and replace it with a plastic intraocular lens that permanently fuses to your eye. Most patients report immediate positive results after cataract surgery. Your double vision should revert back to single vision again and you should experience much more clarity in your sight.
