Cataracts refer to a vision impairment where cloudy vision is caused by a clouding of the lens inside our eye. It is a common and curable vision impairment and is mostly associated with ageing. Most people are expected to develop cataracts over the age of eighty. They can develop in either one or both the eyes. When rays of light enter our eye, they pass through the lens and focus on the retina where they are converted into nerve signals and sent to the brain via the optic nerve. When the lens of our eye becomes cloudy due to cataracts, the rays of light cannot pass through properly, causing our vision to become cloudy. Causes of Cataracts
- In order to understand what causes the lens of eyes to become cloudy, we must understand how the lens work first.
- The lens of our eye is composed of mostly water and protein. The protein is arranged in a very specific manner which ensures the clarity of the lens which allows light to pass through it.
- During the natural process of ageing, the arrangement of protein in our eyes begins to change and some of them clump together and cover a small area of the lens. This is known as a cataract.
- Studies have suggested risk factors for cataracts like smoking and diabetes. However, the cause of cataracts is usually natural wear and tear of the eye as it ages.
- Live a healthy life overall Research has suggested that cataracts can be caused due to lifestyle choices such as cigarettes and alcohol. By aiming towards living a healthy life, you’ll be less likely to develop cataracts.
- Protect your eyes from the sun Exposure to UV rays of the sun is bad for our eyes for various reasons and one of them is that they are also considered to be a cause of cataracts. It is vital to protect your eyes from the shade, especially in the summer, with UV-blocking sunglasses and hats, if needed.
- Visit your ophthalmologist regularly The importance of regular eye examinations cannot be stressed enough. By visiting your ophthalmologist regularly, you can always ensure the good health of your vision.
