What condition refers to the loss of transparency of the lens of the eye?

1. Myopia

2. Glaucoma

3. Cataracts

4. Retinal detachment

The correct answer is: Cataracts

The condition that refers to the loss of transparency of the lens of the eye is cataracts. In cataracts, the lens becomes cloudy, which can impair vision significantly. This condition is often age-related, but it can also be caused by other factors such as diabetes, prolonged exposure to UV light, or trauma. Myopia, on the other hand, refers to nearsightedness, where distant objects appear blurry, but it is not associated with changes in the lens's transparency. Glaucoma is related to increased pressure within the eye, which can damage the optic nerve, while retinal detachment involves the separation of the retina from the underlying tissue, leading to vision loss but does not pertain to lens opacity. Therefore, cataracts is the correct choice as it specifically addresses the issue of lens transparency loss.
