GB/T 10810.5-2025 is a specialized testing standard for evaluating the surface abrasion resistance of ophthalmic lenses, applicable to both coated and uncoated lenses. The standard includes three test methods: the minimum surface abrasion test, the enhanced surface abrasion test, and the falling sand test, which simulate different wear scenarios in practical use. Abrasion resistance is quantitatively assessed using metrics such as changes in haze value. The tests require equipment such as an abrasion tester (with specific rubber tips and steel wool), a falling sand test apparatus, and a haze meter, along with standard abrasives and sample fixtures to ensure reliable results. This standard provides a unified technical basis for quality control and performance evaluation of ophthalmic lenses.
