Which is the lens dose limit for occupational exposure?

Explanation:
Eye lens dose limit for occupational exposure is the maximum annual equivalent dose allowed to the lens of the eye for workers exposed to ionizing radiation. The lens is particularly radiosensitive, so the limit is set lower than whole-body limits to protect vision and reduce the risk of radiation-induced cataracts. Historically, the occupational limit for the lens has been 15 rem per year (about 150 mSv). This is why that option is the best choice. The other values do not align with the established lens limit. Modern guidelines have moved toward about 20 mSv per year averaged over five years (with up to 50 mSv in any single year), but the 15 rem/year figure remains a common standard in many exam contexts.
