Question: 1 / 545

What happens to the lens of the eye in a cataract?

It becomes transparent

It shrinks in size

It changes color

It becomes cloudy, causing vision loss

The lens of the eye becomes cloudy in the presence of a cataract, which leads to vision loss. This cloudiness interferes with the passage of light through the lens, which is essential for clear vision. Normally, the lens is transparent and allows light to pass through it without obstruction. When a cataract forms, it alters the lens’s structure, which can result in a range of visual impairments, such as blurred or dimmed vision, difficulty with glare, and challenges in seeing at night. Over time, if not treated, cataracts can significantly impair daily activities, making it difficult to read, drive, and perform other tasks that require clear sight.
