What is the primary purpose of wearing goggles when tanning?

Wearing goggles during tanning primarily serves to protect the eyes from UV exposure. The skin around the eyes is particularly sensitive and can be at a higher risk of damage from ultraviolet rays. Prolonged exposure to UV light without proper eye protection can lead to serious issues, including cataracts and other eye-related conditions. Goggles are specifically designed to block harmful rays while still allowing for visibility and comfort, ensuring that the delicate skin and tissues around the eyes remain safe during the tanning process. Therefore, using goggles is crucial for maintaining eye health while enjoying the benefits of tanning.

Other options, while they touch on related ideas like comfort or blocking debris, do not prioritize the essential protective aspect that goggles provide against UV exposure, which is critical for safe tanning practices.
