Cataracts

First of all, it helps to know that progressive blurred vision, dull colors, or discomfort with bright lights may have a cataract behind them, which is why an eye exam is worthwhile.

Cataracts are the clouding of the lens, the eye's natural lens, which over time lets in less light and reduces the sharpness of vision.

Common causes: Aging is the most common factor, though diabetes, certain injuries, and prolonged sun exposure also play a role.

Which specialist treats them? The ophthalmologist is the one who studies the lens and evaluates each case. If you notice your vision becoming consistently cloudy, scheduling an evaluation with this specialist is the right step.
