[0002] Optical lenses are optical components made of optical glass or other transparent materials (such as plastic). Their main function is to change the direction of light propagation and to correct vision, such as myopia, hyperopia and astigmatism. Optical lenses have specific optical properties, such as refractive index and transmittance, which can reduce optical problems such as aberration and chromatic aberration.
