What item is crucial for a client's safety in a tanning bed?

Protective eyewear is a crucial item for a client's safety in a tanning bed because it shields the eyes from the harmful ultraviolet (UV) rays emitted during tanning sessions. Long exposure to UV radiation can lead to serious eye problems, including cataracts and other long-term damage. Proper protective eyewear is designed to block these rays, ensuring that the eyes remain safe while the rest of the body receives the tanning benefits.

While dark sunglasses may provide some level of protection, they are not specifically designed for use in tanning beds and may not block the appropriate wavelengths of UV light. Long sleeves can offer some skin coverage, but they do not address the specific eye safety needed in this scenario. Moisturizers are beneficial for skin care but do not contribute to eye safety during tanning. Thus, protective eyewear is the essential item that directly protects a client's eyes and contributes to their overall safety while using a tanning bed.
