It’s no surprise that nearsightedness is the number one eye issue in the world right now. In 2016–2017, we spent an average of 10.4 hours on our devices a day.

Different age levels require different levels of protection. Children under the age of 14 who use tablets and phones with high energy light are at special risk. Until 14, their corneas aren’t fully developed, and lack the protection of adult eyes — especially if they’re constantly in front of a device. Increased and prolonged exposure to HEV is a contributing factor to increased diagnoses of nearsightedness among children.
