How are daily wear contact lenses worn?

• A. Only while awake
• B. Only while sleeping
• C. 24 hours a day
• D. Twice daily

Answer: (A)

Daily wear lenses are meant for use during waking hours and should be removed before sleep. When lenses stay in the eye overnight, the cornea receives less oxygen, which can lead to dryness, irritation, swelling, and a higher risk of infection. That’s why the recommended practice is to wear them only while you’re awake and take them out at night. The other options don’t fit because overnight wear isn’t approved for daily wear, wearing them 24 hours a day isn’t safe, and wearing them twice daily isn’t how daily wear schedules are defined.
