Description
Pawat Chunhachatrachai and Chyi-Yeu Lin present a 2023 algorithm for spotting rim defects in contact lenses on the factory line. Lenses must be safe for eyes, and rim flaws are subtle and uneven, so human checks and older software miss some. Their program, CLensRimVision, works through a fixed chain: clean the image, find the rim as a circle, then unroll it into a flat band.
On the flat band, set rules judge flaws by thickness or by area, so the method adapts to lens types. The final step draws the findings back onto the image for review. The system scored 0.937 on a standard accuracy measure, and the authors offer it as a guide for lens makers.
