What Is Cataract? Here Are 3 Facts You Need To Know

The eyes allow you to see the world and explore its wonders. Unfortunately, certain eye conditions can occur as one grows old. One of the most common eye diseases is the cataract.

Cataracts refer to the opacification or clouding of the eye lens leading to loss of vision. These result from the inability of light rays to pass through the lens. In the early stages of the disease, stronger lighting and eyeglasses may help with vision problems. However, there will come a time that surgery is the only resort left.

Cataracts may be a common eye disease but here are three facts you may not know already.

 

  1. Cataract Is The Leading Cause Of Blindness Worldwide

Across the globe, cataract is the leading cause of blindness. It accounts for about 51 percent of all cases of blindness, which is about 20 million people. Moreover, around 54 million people, a majority of whom live in developing countries, experience moderate to severe vision problem due to cataracts.

 

  1. Sensitivity To Light Is One Of Its Symptoms

There are many symptoms related to cataract including sensitivity to light or photophobia. Other symptoms include cloudy or foggy vision, difficulty seeing at night, and seeing rainbow halos around lights.

 

  1. Advanced Age Is The Most Important Risk Factor

Most cases of cataracts are age-related. This means that the cataract formed as a result of aging. About 50 percent of people will develop cataracts when they reach 65 years old, and almost everyone will have it by 75 years old.

 

The Three Stages Of Cataract

Cataract has three stages – immature, mature and hyper mature. It’s called immature when it covers just a part of the lens. Moreover, it’s dubbed as mature if it prevents the light to pass through the lens and to the retina. When fluid is already leaked to other parts of the eye, it’s dubbed as hyper mature.

 

This eye condition is a sign of aging, but it can be managed as long as you properly take care of your eyes. However, since it’s not preventable, the best thing to do is to make sure the eyes are getting nourished by living a healthy life.
