Optics & the Eye


Here you can find some interesting information about such optical parameters as wavelength, refractive index, transmittance, etc. and the role they play in the field of spectacle lenses.
Visual deficiencies, or "ametropia" as the expert calls them, and the possibilities available to correct them are explained and illustrated in a clear, easy-to-understand way.
You will also receive some useful information not only about the principles behind antireflection coatings, but also about the benefits provided by coated lenses.
