In focus: Chasing away the blues

It has now been nearly three years since the first blue light filtering lens products appeared on the market. While comfort and glare reduction made up part of the story, the headline for their introduction was the filtering of a band of light in the blue spectrum above 380mm.

Among those seeking to educate the public was Essilor with its Seeing Blue initiative, which formed part of the Think About Your Eyes awareness campaign. Earlier research, it said, from the Paris Vision Institute that suggested ‘bad blue light’ could damage cells within the eye. Essilor engaged 400 practices in an awareness campaign.
