Which statement best describes an ideal GP lens fit?

• A. Central alignment with no movement
• B. Central alignment with mid-peripheral bearing, adequate edge clearance, and 1-3 mm of movement
• C. Central touch with excessive edge lift
• D. Central pooling with no bearing

Answer: (B)

An ideal GP lens fit balances where the lens sits on the eye, how it interacts with the corneal periphery, and how it behaves with blinking to keep the tear film healthy. The best description describes a centered lens that has gentle bearing in the mid-periphery, enough edge clearance to avoid pressing on the cornea, and a small amount of movement with each blink (about 1–3 mm). This combination promotes stable alignment over the cornea, supports tear exchange under the lens, and maintains comfort and oxygen access. Central contact would indicate too steep a fit and risk of staining; excessive edge lift means the edge is not supporting the lens properly; central pooling with no bearing shows the lens isn’t vaulting or stabilizing on the cornea, leading to poor tear dynamics.
