The word “cataract” is derived from the Greek word katarraktes which loosely translates to waterfall. It was believed that a congealed fluid from the brain had flowed in front of the lens of the eyes. Today, eye cataract is defined as the clouding of the lens of your eyes.
When proteins present in the eye form clumps, it muddles the vision with a cloudy, hazy outline. It gradually develops and starts interfering with your vision and unless treated could lead to total blindness.
