What Is a cataract? A cataract develops when the clear lens inside the eye becomes opaque, often due to aging, high blood sugar, ocular trauma, specific medications, or prolonged sunlight exposure. Signs may include unclear eyesight, glare and halos around lights, faded colours, frequent power changes, and difficulty with night https://www.deviantart.com/eyeheal/journal/Clear-Vision-Starts-Here-Advanced-Cataract-1332641534
