What is a potential consequence of an eyelid condition on contact lens fitting?

• A. Increased tear production
• B. Decentration or variable movement characteristics of the lens
• C. Improved centration with eyelid movement
• D. No effect on lens fit

Answer: (B)

Eyelids directly shape and move the contact lens on the eye. When an eyelid condition alters lid contour, laxity, or blink pattern, the lens is less likely to stay perfectly centered or to move in a consistent, predictable way with each blink. That can lead to the lens decentring from the visual axis and showing variable movement during blinking, which often causes fluctuating vision, edge awareness, and comfort issues. Increased tear production or improved centration with eyelid movement aren’t typical outcomes of eyelid pathology, and saying there’s no effect ignores how the lid forces and tear film interact with the lens.
