검증된 단계별 안내1
Understand that cataracts are a condition where the lens of the eye becomes cloudy, leading to impaired vision.
Recognize that the lens is primarily composed of crystallin proteins, which are crucial for maintaining its transparency and refractive properties.
Identify that changes or damage to these crystallin proteins can lead to the clouding of the lens, which is characteristic of cataracts.
Consider the structures of the eye: the aqueous humor, lens, and vitreous humor. The lens is the structure directly affected by changes in crystallin proteins.
Conclude that since cataracts involve the clouding of the lens due to changes in crystallin proteins, the lens is the structure directly affected by cataracts.
