METHOD OF MANUFACTURING A PLASTIC LENS |
摘要 |
<p>The present invention relates to a method of manufacturing a plastic lens comprising a cured film on at least one of a pair of opposing surfaces of a plastic lens substrate. The method of manufacturing a plastic lens of the present invention comprises heating the plastic lens substrate to a temperature greater than or equal to a glass transition temperature of the substrate; coating a photocurable composition on at least one of a pair of opposing surfaces of the lens substrate following the heating; forming a cured film by irradiating the photocurable composition that has been coated on the substrate with light to cure at least a portion of the composition; and conducting a heat treatment of the plastic lens on which the cured film has been formed at a temperature, the temperature being lower than the glass transition temperature of the substrate but greater than or equal to a glass transition temperature of the cured film.</p> |
