Rigid gas-permeable (RGP) contact lenses, commonly used in myopia management, can induce discomfort due to frictional interactions with the ocular surface. This study investigates the tribological properties of RGP lenses under different lubricants to assess their impact on corneal and eyelid tissues. Using an in vitro friction testing method that simulates the eyelid- lens interface, the coefficient of friction (COF) and wear characteristics were measured for lenses lubricated with four distinct artificial tear solutions. Results indicate that specific lubricants significantly reduce COF, potentially enhancing lens comfort and minimizing ocular irritation. These findings emphasize the importance of lubricant selection in optimizing RGP lens performance and highlight the relevance of tribological considerations in the development of ocular biomaterials.
