What really causes cataracts? While most people know that age is the biggest factor, many are surprised to learn about the other risks that can significantly accelerate cataract development.
Since cataracts are the leading cause of reversible vision loss worldwide, understanding your personal risk is the first step toward protecting your long-term vision. Here are the most common causes our surgeons discuss with patients:
๐๐ด๐ฒ: The #1 cause. More than half of all Americans have cataracts by the time they are 80 years old as the proteins in the eye's lens naturally change over time.
๐จ๐ฉ ๐ฅ๐ฎ๐ฑ๐ถ๐ฎ๐๐ถ๐ผ๐ป ๐ณ๐ฟ๐ผ๐บ ๐ฆ๐๐ป๐น๐ถ๐ด๐ต๐: This is a major factor here in Texas. Lifelong, unprotected sun exposure causes cumulative and irreversible damage to the lens, speeding up clouding.
๐ฆ๐บ๐ผ๐ธ๐ถ๐ป๐ด: A significant and controllable risk. Smokers are 2 to 4 times more likely to develop cataracts than non-smokers due to the toxic damage to the lens.
๐๐ถ๐ฎ๐ฏ๐ฒ๐๐ฒ๐ & ๐๐น๐ผ๐ผ๐ฑ ๐ฆ๐๐ด๐ฎ๐ฟ: Uncontrolled blood sugar can cause chemical changes within the lens, often leading to earlier and more rapid cataract formation.
The good news? While you can't stop aging, some of these risks are manageable. In our new, comprehensive guide, we cover all the risk factors in detail and provide a full list of prevention strategies to help you slow progression.

Cataracts can affect people of all ages, although they occur the most often in people aged 65 and up. The condition usually occurs in both eyes, but they often form at different rates.
