Whether at home or at work, exposure to computer screens creates extreme and harmful conditions known as Digital Eye Fatigue
(DEF) and Computer Vision Syndrome (CVS). Collectively, the condition is popularly known as ”Computer Eye Strain”.


The cause is primarily the poor definition of images and text on a computer screen creating a repetitive refocusing effort for the eye
muscles. This effort, sub-conscious but real, leads to a variety of symptoms including blurred vision, headaches, or dry, irritated eyes as
well as neck and back aches.


According to The Vision Council, The American Optometric Association has estimated that 70 to 75 percent of the 140 million Americans
using computers would benefit from corrective computer eyewear.


During the final developmental stages of our Crystalion-3 lenses, we concentrated on providing a real solution for this widespread
problem. Our lenses help to relax the ocular muscle that is responsible for focusing at close distances, thereby reducing strain. Our
formula includes an amber tint that helps to eliminate additional optical stress from external light sources such as fluorescent lights.
And our unique anti-reflective properties filter out harmful light that emanates from the computer screen, while soothing the eyes
thereby creating a powerful and truly effective solution to this pervasive and destructive problem


Blue Shark Optics, with its revolutionary Crystalion-3 technology, provides the most advanced and effective over-the-counter solution
in today’s market.
