Why this is the answer
Protecting the client's eyes during certain facial treatments — for example with eye pads or by keeping products away from the eye area — is important because products, steam, exfoliants, or bright treatment lights could irritate or harm the eyes. The cosmetologist takes care around the delicate eye area and shields the eyes when appropriate. Client safety includes protecting sensitive areas like the eyes during services. Recognizing this precaution is part of the careful, safety-minded facial practice the exam reinforces.
