Which of the following is a common fit issue indicating improper lens fit?

• A. Clear centration and stable vision
• B. Lens moves minimally
• C. Excessive lens movement
• D. Comfort remains good

Answer: (C)

Movement on the eye is a key sign of how well a soft lens fits. Some movement with each blink is normal to allow tear exchange and keep the lens centered, but excessive movement means the lens isn’t adequately stabilized on the cornea and lid. When a lens moves too much, it won’t stay centered, vision can blur or fluctuate between blinks, and there’s a higher risk of discomfort or the lens dislodging. The other signs describe a good fit—clear centration, stable vision, and comfortable wear—so they indicate proper fit rather than an issue.
