What are the possibilities of having cataracts?


There are several factors and mechanisms involved in the formation of cataracts:

  1. Aging: The most common cause of cataracts is the natural aging process. As we get older, the proteins in the lens of the eye may start to break down and clump together, clouding the lens. This process is gradual and can occur in both eyes but may progress at different rates.

  • Ultraviolet (UV) Radiation: Chronic exposure to UV radiation from the sun is a risk factor for cataracts. UV rays can cause damage to the proteins in the lens over time, contributing to the development of cataracts. Wearing sunglasses with UV protection can help reduce this risk.


  • Smoking and Alcohol: Consumption have been linked to an increased risk of cataracts. These behaviors can introduce harmful chemicals and oxidative stress to the eye, accelerating the formation of cataracts.


  • Diabetes: People with diabetes are at a higher risk of developing cataracts. High blood sugar levels can cause changes in the lens that lead to cataract formation.


  • Trauma or Injury: Physical injury to the eye can damage the lens and lead to cataracts. This can occur due to accidents, sports injuries, or surgical complications.


  • Medications: Some medications, such as corticosteroids and certain types of eye drops, can increase the risk of cataracts when used over a long period. It's essential to discuss the potential side effects of medications with your healthcare provider.


  • Genetics: Some individuals may have a genetic predisposition to developing cataracts. If cataracts run in your family, you may be at a higher risk.


  • Other Medical Conditions: Certain medical conditions, such as hypertension, obesity, and eye conditions like glaucoma, can increase the likelihood of cataract formation.

 

Fact : According to an Australian study, people with dark brown eyes are 2.5 times more likely to acquire cataracts than people with other eye colors. Researchers believe this is due to the higher amount of UV light absorbed by dark brown eyes.
