When inspecting a contact lens before insertion, what should you look for?

• A. Defects or debris on the lens
• B. The lens color pattern
• C. The brand logo on the edge
• D. The time since opening

Answer: (A)

Before inserting a lens, the key is to confirm it is clean and physically undamaged. A lens with defects or debris can cause irritation, corneal scratches, or even infection, so you inspect for visible flaws on the surface—scratches, chips, tears, nicks, or rough edges—and for any dust, protein buildup, or dried residue. If you find any defect or debris, the lens should not be worn; replace it with a new one and rinse if needed. The color pattern or logo on the edge is cosmetic and does not affect safety, while the time since opening relates to shelf life, not the lens’s immediate condition. Focusing on a clean, intact surface helps protect comfort and eye health during wear.
