Problems solved by technology

[0002] As we all know, myopia is the most common and frequent eye disease in my country. Contact lenses (contact lenses) are favored by more and more patients, especially young people, for their convenience, comfort, aesthetics, large field of view, and real images. , the application is increasing year by year; in recent years, with the entry of various new contact lenses (RGP, OK lens, etc.) As a result, it is difficult for the user to observe the protein, lipid pollution, scratches, scratches, and tiny cracks on the surface of the contact lens (contact lens) with the naked eye, in addition to reducing the contact lens (contact lens) The lower the light transmittance, the lower the correction effect, hinder the normal use of the user, and induce corneal complications
