photochromic
The principles, characteristics, and measurement methodology of photochromism of plastic ophthalmic lenses are briefly introduced and discussed. The factors influencing measurement variation and accuracy, including the preconditioning process, measurement device, and procedure, were investigated on ophthalmic photochromic lenses covering both photocasting and photocoating lens technologies.
