Abstract: PURPOSE: A method for preparing a photochromic plastic lens is provided, to obtain a photochromic plastic lens which has good refractive index, surface hardness and photochromism lifetime and whose refractive index can be controlled widely by the change of the composition, by varying the curing temperature and time. CONSTITUTION: The method comprises leaving a photochromic resin composition at a temperature of a room temperature to 70 deg.C for 30-360 min to initiate the degradation reaction of an initiator; maintaining the temperature at 70-80 deg.C for 110-180 in; maintaining the temperature at 85-95 deg.C for 110-130 min; maintaining the temperature at 110-130 deg.C for 30-240 min; and cooling the thermally cured one naturally. The photochromic resin composition comprises 100 parts by weight of at least one monomer selected from the aromatic radical polymerizable monomers represented by the formula 1; 0.001-90 parts by weight of at least one photochromic compound selected from the group consisting of diarylethene-based one, Spirobenzopyran-based one and diazo-based one absorbing the light with the wavelength of 250 nm or more; and 0.1-10 parts by weight of a photoinitiator.
