Can nuclear sclerosis be cured?

Is nuclear sclerosis bad?
If the nuclear sclerosis is severe enough, it’s called a nuclear cataract. The proteins in the lens start to clump, scattering light instead of allowing it to pass through. Cataracts cause about half of all blindness in the world, and nuclear cataracts are the most common type.
How bad is a Grade 3 cataract?
Correct! A 3+ cataract. This cataract is so dense that the cortex has liquefied, allowing the nucleus to sink to the bottom of the lens capsule. This special type of very dense cataract is known as a Morgagnian cataract.

Need for brighter light for reading and other activities. Seeing “halos” around lights. Frequent changes in eyeglass or contact lens prescription. Fading or yellowing of colors.
What is a nuclear sclerotic cataract?
A nuclear sclerosis cataract, also referred to as a nuclear cataract, grows in the central part of the natural lens. Nuclear cataracts commonly occur with age, but they may appear early. Knowing some of the causes and risk factors may help a person understand the condition. .
