BluTech’s journey into blue light solutions began in 2010 following family tragedy — three of our founder’s grandparents lost their vision to age-related macular degeneration, to which blue light is a contributor. Some brands offer style but little in the way of actual protection against blue light. Some brands block blue light beyond the harmful range, which alters how you see colors — only BluTech lenses provide complete protection against harmful blue light while offering an attractive, near-clear look. No other lens promotes lifelong healthy vision by delivering true-to-life color while filtering out the right amount of blue light known to cause eyestrain, headaches, migraine attacks, and sleep cycle disruption.
