Final answer:
Cataracts obscure the lens of the eye, leading to clouding that impedes vision. Sunglasses with UV protection can help prevent cataracts, and surgery to replace the lens is a common treatment.
Step-by-step explanation:
The part of the eye that may be obscured by cataracts is the lens. Cataracts cause a clouding of the lens, which impairs vision by blocking or altering the passage of light into the eye. While the lens should be clear to focus light properly on the retina, cataracts can cause it to become opaque, leading to blurred or diminished vision. Cataracts are often related to aging, with a significant percentage of individuals between the ages of 65 and 74 experiencing this condition. Prevention is crucial, and measures such as wearing sunglasses that protect against UV light can help. Treatments typically involve the surgical replacement of the clouded lens with an artificial one to restore vision.
Cataracts are a clouding of the lens of the eye, which can lead to a loss of vision. When cataracts form, the lens becomes opaque and obscures the passage of light through the eye. As a result, the part of the eye that may be obscured by cataracts is the lens itself.
The lens of the eye is normally transparent and helps to focus light onto the retina, which is located at the back of the eye. When the lens becomes clouded by cataracts, it can prevent light from properly reaching the retina, causing blurred or diminished vision.
