What are brown cataracts?
A brunescent, or brown, cataract is often correlated with the maturity of a cataract and can cause decreased visual acuity. Brunescent cataracts can cause poor contrast and color discrimination, especially at the blue end of the visible light spectrum.
What is black cataract?
Black cataract is very specific. The lens nucleus has become so hardened, sclerotic and blackened that it has gone beyond what is known as brunescence. Brunescence is a discoloration of the nucleus that occurs as the nucleus becomes sclerotic. Brunescence begins as a yellowing and progresses to orange and brown.
