Did you know, cataracts are the leading cause of blindness in the world? Cataracts affect nearly 20.5 million Americans age 40 and older.* If you are over the age of 50, you should have a yearly comprehensive eye exam to detect cataracts as they develop.
A cataract is the clouding of the lens in your eye. Many people describe the feeling as if you are looking through a foggy or frosted window.
Clouding of the natural lens in your eye is caused by proteins clumping together within the lens. It is unknown why the eye changes as the body ages, but these changes may cause cataracts to grow larger over time, resulting in an increased difficulty to see clearly.
Some factors that have been linked to cataract development are diabetes, obesity, smoking, ultraviolet radiation, and family history.
Symptoms associated with cataracts can vary from person to person. However, there are a few key symptoms associated with most cases of cataract development. If you are experiencing one or more of these symptoms, schedule a visit with your eye doctor to discuss your risk or development of cataracts.
Subcapsular cataracts typically occur in the back of the lens and are most common in individuals with diabetes or those taking a high dose of steroid medication.
Nuclear cataracts are associated with aging and occur in the central zone of the lens.
Cortical cataracts occur in the lens cortex and are associated with streaks which interfere with light passage through the eye.
Congenital cataracts are present at birth and may be due to genetics or intrauterine infection.
No studies have shown a way to prevent cataracts, however, there are recommended practices to help maintain eye health and lower your risk of developing cataracts.
