Which category would include lens changes due to exposure to certain chemicals?

• A. Nutritional
• B. Environmental
• C. Traumatic
• D. Toxic

Answer: (D)

Exposure to certain chemicals damages the lens through toxic effects, causing cataract-like changes. This category covers lens opacities produced by toxins or chemical exposures that disrupt lens proteins and metabolism, leading to opacification. Nutritional cataracts come from dietary or metabolic deficiencies affecting lens nutrition, not direct chemical exposure. Environmental cataracts are due to external factors like UV light or radiation, and traumatic cataracts result from physical injury to the lens. So, when the question mentions changes from exposure to chemicals, the toxic category is the best fit.
