During the palm test, which result indicates a good GP lens edge?

• A. should glide smoothly and feel comfortable
• B. is palpably rough to touch
• C. should glide easily and feel smooth
• D. sticks and drags across the palm

Answer: (C)

The palm test checks how the GP lens edge interacts with skin—whether the edge is smooth and rounded enough to move over the palm without catching. A good edge will glide easily across the skin and feel smooth, indicating the bevel height and edge profile are balanced for comfortable wear. When the edge is smooth and easy to slide, it suggests the lens will not irritate or snag on blinking or insertion. If the edge feels rough or stops or drags, that points to an edge that’s too sharp or irregular, which can cause discomfort or irritation. So the statement that the edge should glide easily and feel smooth best captures the desirable outcome of a properly finished GP lens edge.
