We all know how important it is to protect our eyes from the sun's harmful UV rays; but what about the harmful effects of blue light rays? Most of us spend the majority of our waking hours staring at a digital screen. Studies suggest that 60% of people spend more than 6 hours a day in front of a digital device. Where is Blue Light? Blue light is actually everywhere. When outside, light from the sun travels through the atmosphere.

Rinse the lens again to remove the loosened debris, making sure to take as long as the package directs: Rinsing is an important step. Place the lens in your clean lens case or lens holder and fill with fresh solution; don't "top off" your old solution. Disinfecting kills microorganisms on the lens. Disinfection time varies from product to product; check the package for details. Repeat steps two through four for your other lens.
