PURPOSE:To easily produce the title lens to a desired color by coating a synthetic resin on a specific optical glass lens to 1-50mu thickness and curing the coating, then dyeing the resin. CONSTITUTION:The synthetic resin is coated by a spin system or immersion system on the optical glass lens having 1,400-1,900nd refractive index, 30-80d resolving power and 1.0-5.0sp.gr. to 1-50mu thickness and is cured by heat or photosetting. The lens is immersed in a bath prepd. by dissolving a dyeing agent after the curing and is thereby dyed. The lens colored to the assigned and desired color is thereby produced in a short period of time. |
