What is characterized by the opacity of the lens and/or capsule of the eye?

The condition characterized by the opacity of the lens and/or its capsule in the eye is known as a cataract. When the lens becomes cloudy, it interferes with the transmission of light, leading to blurry vision and difficulty seeing clearly. Over time, cataracts can worsen and may require surgical intervention to restore clear vision, often through lens replacement.

In contrast to cataracts, the other terms refer to different structures or conditions. The cornea is the clear front surface of the eye, important for focusing light but not directly associated with lens opacity. The canthus refers to the inner or outer corners of the eye where the upper and lower eyelids meet, irrelevant to lens opacity. The cochlea is a spiral-shaped organ in the inner ear that is essential for hearing, having no direct connection to the lens or its conditions.
