What Is cataract? A cataract forms when the clear lens inside the eye becomes opaque, often due to aging, high blood sugar, ocular trauma, certain medicines, or long-term UV exposure. Signs may include unclear eyesight, glare and halos around lights, dull colours, frequent power changes, and trouble driving at night. https://medium.com/@kaushal.wockhardthospitals/clear-vision-starts-here-advanced-cataract-eye-surgery-in-mulund-c7f0fe795886
