Cataracts are a common eye condition that can cause blindness if left untreated. They form when proteins in the lens of the eye clot, creating an opaque layer. Surgery is the only way to remove cataracts, but corrective lenses may be used first. Protecting the eyes from UV radiation and eating a healthy diet can help prevent cataracts.
A cataract is an opacity that forms on the lens of the eye, initially making vision blurry or cloudy. If left untreated, cataracts cause blindness; in fact, they are the leading cause of blindness in the world. Cataract blindness can come on slowly, which is why it’s important for people to have regular eye exams to make sure their eyes are healthy. Fortunately, blindness caused by cataracts can be treated, especially if caught early, and surgery has a good success rate.
The cause of cataract blindness is not known. Many older people suffer from cataracts, suggesting they may be part of the aging process. They have also been linked to diseases such as diabetes, radiation exposure, trauma to the eye, or eye surgery to correct other conditions. The mechanism by which cataracts form, however, is fully understood, leading to the ability to cure it.
While some people think of a cataract as a growth on the eye, it actually forms inside the eye. Cataracts occur when proteins in the lens begin to clot, forming a thick, white layer of opaque material. Initially, a patient may not be aware that they have this problem and may attribute the decline in their ability to see to the need for new glasses. The only way to fix the problem is to have the cataract surgically removed.
There are three main types of cataract blindness. The most common type begins with a nuclear cataract, which forms in the core of the eye. Patients often notice this type of cataract early on, as the core is in the center of the eye. Cortical cataracts form along the edges of the eye and move toward the center. A loss of peripheral vision is a symptom of this condition. A subcapsular cataract forms on the back of the lens.
Eye surgery can be an intimidating and scary prospect, but cataract blindness is also scary. If a person is diagnosed with cataracts, surgery may not be recommended right away. Many medical professionals use corrective lenses to improve vision first, although they may ultimately recommend surgery. People who have cataracts should talk to their doctor about their options and consider them carefully.
There are some steps that can reduce the likelihood of developing this form of blindness. Some doctors believe that ultraviolet radiation is harmful to the eyes, so people should protect their eyes with sunglasses and face shields. Eating a diet rich in healthy vitamins and minerals can also help. Eventually, however, cataracts can form despite an individual’s best efforts.
