  • Publication number: 20190211258
    Abstract: Provided is a photochromic lens in which a transmittance at 23° C. after irradiation using a xenon lamp at an illuminance of 50,000 lux for 15 minutes satisfies the following conditions. (1) A transmittance at 550 nm is 25% or less. (2) A transmittance a at 550 nm is larger than a minimum transmittance b between 575 nm and 600 nm, and a difference between the transmittance a and the transmittance b is 5% or more. (3) There are one or more points of inflection in a transmittance curve from 550 nm to 600 nm.
