This dangerous infection of the cornea can lead to a permanent scar and is more common in people wearing extended wear lenses who are leaving their contact lenses in the eye overnight. If you are over the age of forty, you may want to consider the option of monovision , where one eye is fit for distance and the other for reading. This solution dose not work for everyone, but is a successful solution for individuals who are very motivated to not wear glasses at all and willing to accept some compromise in the vision. Of course, if you want to get out of your contact lenses altogether, you can always consider laser vision correction . Because we look directly through the lens in order to see, this clouding causes blurred vision.
Cataracts are the major cause of treatable vision loss in the United States.
Cataracts can occur at any age but are more common as people get older. Some cataracts do not cause much of a problem with vision and do not need any treatment. If the vision is blurred and cannot be corrected with glasses, or if you cannot pass a driver's test, or if your doctor cannot see the back of your eye through the cataract, you may need cataract surgery . Although there is some evidence that vitamin C may have some effect at slowing the progression of cataracts, there is no medical treatment for cataracts once they have affected the vision. About 1.5 million cataract surgeries are performed yearly in the United States.
