The Gunnar Optiks G0005-C011 SheaDog Advanced Computer Glasses are the only eyewear recommended by doctors to protect and enhance your vision when viewing digital screens at home or in the office. Eye strain, visual stress and dry eyes can be caused by extended periods of digital screen viewing and office lighting. Stay focused and perform more efficiently throughout the day with these stylish mercury frame glasses designed to improve visual performance, enhance focus and reduce eye strain for those with 20/20 vision. The SheaDog reduced frame height delivers full coverage performance, while fitting a wide range of face shapes; its low profile temples provide headset compatibility and long haul ergonomics. The Amber tint lens makes these glasses perfect for computer and video gaming as it increases gaming precision and graphics. Their 56-millimeter wide lens design frames your face to protect your eyes from dry air currents, effectively preventing irritation. GUNNAR’s anti-glare lens coating is specifically engineered to filter out the harsh, high-energy part of the spectrum, reduce digital eye strain and enhance viewing detail. The SheaDog’s 130-millimeter temples, full rim frame and fastener-free hinge are composed of stainless steel and designed to generate proper strength and optical stability. Weighing in at only 20-grams, these lightweight glasses are properly balanced to reduce pressure points and combat eye strain. Keep your glasses in place with the 18-millimeter nose bridge and adjustable pads that articulate (3) dimensions for a dynamic fit. Micro-engineered locks securely retain the lenses without undue stress or distortion to the optics, while the one piece front construction eliminates all welds, screws and other potential points of failure. The Gunnar Optiks G0005-C011 SheaDog Full Rim Ergonomic Advanced Computer Glasses come with a 1-year limited warranty against manufacturing defects. The ultimate result is improved clarity, focus and performance that meet the demanding visual needs of a new generation.
