What is the annual dose limit for the lens of the eye?

Explanation:
The lens of the eye is especially sensitive to radiation, so there is a dedicated annual limit to protect vision from cataracts. For workers exposed to radiation, the limit is 15 rem per year (150 mSv). This lower limit compared to whole-body limits reflects the higher risk to the eye from accumulated dose over time. To stay within this limit, use shielding such as leaded eyewear or barriers, maximize distance from the source, and keep exposure time as short as possible, while monitoring lens dose with appropriate dosimetry. If the lens dose trends toward this limit, review and adjust procedures to reduce exposure. The other numeric options do not represent the standard occupational lens dose limit.
