Abstract

PURPOSE: To obtain abrasion resistant dimming spectacle lenses which respond rapidly to light, are stable over a long term and do not cause disappearance of a photochromic substance due to volatilization by forming the photochromic substance on the surface of each spectacle lens in contact with a water retaining transparent resin.
CONSTITUTION: An antistatic liq. prepared by mixing methylolmelamine, polyethylene glycol and a plasticizer is applied to the surface of lens 1 of CR-39 (acrylic diglycol carbonate polymer) and baked to form water retaining transparent resin layer 2. SrTiO3 is then vapor deposited using compacted tablets of SrTiO3 contg. trace amounts of Fe3+ and Mo5+ added to form photochromic layer 3, and protective water retaining resin film 4 is formed on layer 3 using the above-mentioned water retaining transparent resin. Thus, dimming spectacle lenses are obtd. Photochromic layer 3 may contain spiropyran or metal dithisonate, and on water retaining layer 2 SiO2.nH2O may be formed by vapor deposition.
