PHOTOCHROMIC FILM, PHOTOCHROMIC LENS COMPRISING THE SAME, AND METHOD OF MANUFACTURING PHOTOCHROMIC LENS |
摘要 |
<p>The present invention relates to a photochromic film comprising a photochromic dye and a resin component. The photochromic film has a nanoindentation hardness of equal to or greater than 800 nm on at least one of surfaces, surface A, thereof. The present invention further relates to a method of manufacturing a photochromic lens. The method of manufacturing a photochromic lens of the present invention comprises forming a photochromic film having a nanoindentation hardness ranging from 500 to 5000 nm on an outermost surface thereof as well as having a smaller nanoindentation hardness on a surface facing a first mold than that on the outermost surface by coating a photochromic liquid comprising a photochromic dye and a curable component on one surface of the first mold for formation of one of surfaces of a lens and subjecting the photochromic liquid to curing treatment, and a photochromic lens comprising a photochromic film on a lens substrate is obtained by means of the above first mold.</p> |
