Nuclear Sclerotic Cataracts- is the most common type of cataract and it is primarily caused by the hardening and yellowing of the lens over time.
Cortical Cataracts-refers to the white opacities, or cloudy areas, that develop in the lens cortex, which is the peripheral edge of the lens. People with diabetes are mostly at risk for cortical cataracts.
Posterior Subcapsular Cataracts-it begins as a small cloudy area on the back surface of the lens and it forms beneath the lens capsule, which is a small "sac" or membrance that encloses the lens and holds it in place. People who use steroids, have diabetes, extreme nearsightedness, or retinitis pigmentosa may develop this type of cataract.
