Before inserting a lens, what should you inspect on the lens?

• A. Color of lens
• B. Defects, deposits, debris, inversion
• C. Brand
• D. Expiration date

Answer: (B)

Before inserting a lens you should inspect the lens surface for any signs of damage or contamination and confirm it’s oriented correctly. Check for defects like scratches, tears, or chips that could scratch the cornea or cause discomfort. Look for deposits or debris on the lens that could irritate the eye or interfere with clear vision. Also make sure the lens isn’t inverted; an inside-out lens often feels uncomfortable, may not align with the eyelid properly, and can affect movement and tear exchange. Colors, brand, or expiry date aren’t reliable indicators of the lens’s immediate condition—expiry is important for safety, but you primarily assess the actual lens surface and fit before insertion to prevent irritation or injury. Focusing on defects, deposits, debris, and inversion helps ensure a safe, comfortable wear from the first blink.
