Which instrument is commonly used to evaluate the GP lens edge?

Evaluating the edge of a GP lens hinges on seeing the bevel and contour clearly to ensure comfortable lid interaction and proper wear. A projection magnifier provides strong magnification of the lens edge and projects its silhouette, making it easy to judge bevel width, edge smoothness, and any nicks or irregularities quickly and accurately. This off-eye check is particularly useful for confirming edge geometry, while a lens loupe offers less detail, a slit lamp can be used for on-eye or general edge observation but isn’t as precise for edge profiling, and a spectrometer measures light properties rather than the edge shape.
