What condition is characterized by cloudy vision due to lens opacities?

Cataracts are characterized by cloudy vision resulting from opacities in the lens of the eye. As cataracts develop, the clarity of the lens diminishes, leading to a gradual reduction in vision quality. This condition can affect one's ability to see clearly at different distances, cause glare and halos around lights, and overall decrease visual acuity.

It is essential to note that while other conditions like myopia (nearsightedness), glaucoma (an eye condition that can cause damage to the optic nerve), and presbyopia (age-related difficulty in focusing on close objects) impact vision, they don’t specifically relate to lens opacities, which are the defining characteristic of cataracts. Thus, cataracts represent a specific change in the eye's lens structure that leads to clouded vision, distinguishing it clearly from the other conditions listed.
