The word Cataract is used to describe a natural “crystalline lens” that has turned cloudy. Cataracts are not a disease, but rather a condition affecting the eye. In the United States, the incidence of age-related Cataract has been reported to be approximately 42% in those aged 52 to 64, 60% in those aged 65 to 74 and 91% in those aged 75 to 85.
In order for you to have clear vision, light must be able to pass through transparent optical structures of your eye to focus properly on the retina. When we are younger, the crystalline lens is usually soft, flexible and has excellent transparency and optical clarity. However, as we progress through life--and are exposed to a lifetime of ultraviolet light--the normally “crystal” clear lens may gradually become yellow and cloudy. When this occurs, you may experience a mild blurring of your vision and you may notice that it is not as easy to see well in dim illumination. Colors may start to seem faded. This cloudiness may also create glare, haloes, and light sensitivity. When the cloudiness worsens, you will notice a significant decrease in both your day and night vision; at this point in time cataract surgery is necessary to restore clear vision.
