I fail to see the purpose of these... unless they are for prescriptions... then I suppose but if they are just clear "safety" glasses, what is the point?
Well, by going to their website I understand... maybe a bit of actual product description would help move these... probably not.
You spend most of your waking hours glued to your computer screen, smart phone, tablet or TV monitor. As the hours go by, you subject your eyes to harsh, high intensity blue light and glare from your screen. Constant viewing of digital screens can create visual stress, eye fatigue, dry eyes, irritation, and even headaches, leading to an obvious conclusion – staring at a computer for long hours can take a toll on your eyes.
GUNNARS increase contrast, comfort and focus while minimizing eye fatigue and visual stress for anyone who spends long hours staring at digital screens. GUNNAR eyewear is powered by i-AMP lens technology comprised of a proprietary lens material in an advanced geometry tuned for intermediate viewing distance and finished with custom formulated lens filters, tints and coatings.
