• How Cataract develops and how to correct it?

Quite many people around world have cataracts, which causes cloudy, blurry or dim vision and often develops with advancing age. As everyone grows older, the lenses of their eyes thicken and become cloudier. Eventually, they may find it more difficult to read street signs. Colors may seem dull. These symptoms may signal cataracts, which affect about 70 percent of people by age 75.


Here are few facts about cataract:

● Age isn’t the only risk factor for cataracts. Though most everyone will develop cataracts with age, recent studies show that lifestyle and behavior can influence when and how severely you develop cataracts. Diabetes, extensive exposure to sunlight, smoking, obesity, high blood pressure and certain ethnicities have all been linked to increased risk of cataracts. Eye injuries, prior eye surgery and long-term use of steroid medication can also result in cataracts.

● Cataracts cannot be prevented, but you can lower your risk. Wearing UV-blocking sunglasses(contact us for it) and brimmed hats when outside can help. Several studies suggest that eating more vitamin C-rich foods may delay how fast cataracts form. Also, avoid smoking cigarettes, which have been shown to increase the risk of cataract development.

● Surgery may help improve more than just your vision. During the procedure, the natural clouded lens is replaced with an artificial lens called an intraocular lens, which should improve your vision significantly. Patients have a variety of lenses to choose from, each with different benefits. Studies have shown that cataract surgery can improve quality of life and reduce the risk of falling.

There are several possible risk factors for cataracts, such as:

● Age
● Intense heat or long-term exposure to UV rays from the sun
● Certain diseases, such as diabetes
● Inflammation in the eye
● Hereditary influences
● Events before birth, such as German measles in the mother
● Long-term steroid use
● Eye injuries
● Eye diseases
● Smoking

Although rare, cataract may also occur in children, approximately three out of 10,000 children have a cataract. Pediatric cataracts often occur because of abnormal lens development during pregnancy.

Fortunately, cataracts can be corrected with surgery. Ophthalmologists who specialize in medical and surgical eyecare perform around three million cataract surgeries each year to restore vision to those patients.
