Understand Cataracts - Causes, Treatments and Prevention
Millions of people suffer from cataracts, a condition that is common. Cataracts are characterized by a clouding in the lens of the eye. If left untreated they can cause blurred vision or even blindness. The condition most commonly affects people over the age of 60. However, it may also develop in younger individuals due to a variety of factors. Understanding cataracts and their causes can be helpful in maintaining good eye health.
What are cataracts?
The lens can become cloudy, causing blurred or hazy sight. Normal clear lens bends light to focus it on retina. The lens becomes cloudy and light cannot pass easily through it. This leads to blurred vision. The World Health Organization says that cataracts account for about 20% of blindness in the world.
Cataracts: Common Causes
Among other factors, cataracts are formed by:
- The most common reason is age. Lens cloudiness is caused by changes in lens fibers that cause a yellow-brown buildup.
- Diabetics are at greater risk of developing cataracts.
- The sun's ultraviolet light can cause cataracts.
- Factors of lifestyle: Alcohol and smoking can cause cataracts.
Cataract Treatment
There are multiple treatments for cataracts.
- Surgery is the most effective way to treat cloudy lenses. The lens will be surgically removed and replaced with a new artificial one. About 90% of the patients who undergo this procedure regain useful vision.
- Contact lenses or glasses can improve your vision at the early stages of cataract formation.
Experts' Opinions about Cataracts
Regular eye exams are essential for the early detection of cataracts and their treatment. The American Academy of Ophthalmology recommends that adults have an eye exam at least one time between 20-29 years old, twice between 30-40, and then a baseline screening at age 40.
Prevention and Natural Remedies
Although there is no way to completely prevent the development of cataracts, some lifestyle changes may help slow down their progress.
- Eat a diet high in vegetables and fruits, especially those that are rich in vitamins C and A.
- Limit alcohol and stop smoking.
- Wear sunglasses that offer UV (ultraviolet) protection to protect your eyes.
- Diabetes and other chronic diseases can be managed.
