There are many jobs that demand the use of hand held devices, RF scanners, or other portable devices. All of these devices emit blue light which has been known to cause eye fatigue, headaches, and migraines. Many of these jobs are also indoor and until recently a wearer that needed to block a good portion of blue light had to resort to amber lenses. The negative to amber lenses other than the yellow shade is it distorts color recognition. With MAXBLUE™ lens technology a worker can wear a clear lens that has a very faint mirror hue, yet while still blocking 41% of blue light. Pretty incredible!
High velocity impact safety glass test method is performed by shooting a 1/4" steel ball at a speed of 150 feet per second aimed at the center of the lens. The result is a Pass or Fail which determines that a lens must not chip, break, or crack and it must maintain its original position in the frame.
