What Is a cataract? A cataract forms when the natural lens of the eye becomes blurred, often due to aging, diabetes, eye injury, specific medications, or prolonged sunlight exposure. Signs may include unclear eyesight, glare and halos around lights, faded colours, frequent changes in spectacles, and difficulty with night driving. https://www.quora.com/profile/Mahesh-Nadgir/Clear-Vision-Starts-Here-Advanced-Cataract-Eye-Surgery-in-Mulun
