Which body part is particularly vulnerable during tanning without protection?

The eyes are particularly vulnerable during tanning without protection because they can be severely affected by ultraviolet (UV) radiation. The skin around the eyes is thinner and more sensitive than other areas of the body, and the eyes themselves do not have any protective pigments like the skin does. Exposure to UV rays can cause a range of issues, from temporary conditions such as photokeratitis, often described as "sunburn of the eye," to more serious long-term problems like cataracts and other forms of eye damage.

Additionally, the eyelids are often overlooked but are also susceptible to UV exposure, increasing the risk of skin cancers in that region. Because the eyes lack melanin, which provides some protection against UV rays, it is critical to use protective eyewear when tanning to prevent potential damage.
