Figure 1. Experimental groups and experimental protocol for CR-39™ spectacle lens protection. A: Daily UVB light exposure (indicated by arrows) once daily to a total amount of 0.72J/cm2 was performed from Day 1 to Day 7, with or without CR-39™ spectacle lenses. No lens was given to the UVB group or the blank
control group. B and C: An actual experimental preparation of mouse eyes covered with CR-39™ spectacle lens was demonstrated. A representative mouse,
after being anesthetized, covered by a CR-39™ lens with UV400 and photochromic coating, and was exposed to UVB.
