Abstract
The invention discloses a method for producing a base color-free polarized lens. The method comprises the following steps of: 1) decoloring, 2) once pouring, 3) strong electromagnetic field acting, 4) primary solidifying, 5) releasing, 6) edging, 7) lens cleaning and 8) secondary solidifying. According to the invention, the base color-free polarized lens is produced through the steps of decoloring by a method of quenching superfluous iodine by using a saturated sodium thiosulfate solution and once pouring molding on the basis of the principle that the strong electromagnetic field is utilized to highly orderly arrange iodine crystals to generate polarized light, and the base color-free polarized lens has excellent polarizing effect and good visual performance; the light transmittance of the base color-free polarized lens can be up to 90%-96%. The method is suitable for all weather and can be widely applied to other outdoor eye protection articles such as optical lenses, base color-free polarized photochromic lenses, resin solar lenses, optical camera lenses and vehicle windshields.
