Answer:
Nuclear Sclerotic Cataracts
A nuclear cataract is the most common type of cataract, beginning with a gradual hardening and yellowing of the central zone of the lens also known as the nucleus. Over time, this hardening and yellowing will expand to the other layers of the lens.
Cortical Cataracts
A cortical cataract forms in the shell layer of the lens known as the cortex and gradually extends its “spokes” from the outside of the lens to the center. These fissures can cause the light that enters the eye to scatter, creating problems with blurred vision, glare, contrast and depth perception. People with diabetes are at risk for developing cortical cataracts.
Posterior Subcapsular Cataracts
Primarily affecting one’s reading and night vision, this type of cataract begins as a small opaque or cloudy area on the posterior (back surface) of the lens. It is called subcapsular because it forms beneath the lens capsule which is a small sac or membrane that encloses the lens and holds it in place.
