The Gunnar Optiks PHA-00101Z MLG Phantom Advanced Gaming Glasses are the only gaming eyewear recommended by doctors to protect and enhance your vision when playing videogames for an extended period of time. Eye strain, visual stress and dry eyes can be caused by extended periods of digital screen viewing, so put yourself back in the game with these stylish onyx frame glasses designed to improve visual performance, enhance focus and reduce eye strain for those with 20/20 vision. The Amber tint lens makes these glasses perfect for computer and video gaming as it increases gaming precision and graphics, while the ultra slim temples help distribute headphone pressure and ensure headset compatibility. Their 57-millimeter wide lens design frames your face to protect your eyes from dry air currents, effectively preventing irritation. GUNNAR"s i-AMP lens technology is specifically engineered to filter out the harsh blue light from digital screens, reduce eye strain and enhance viewing detail so you can stay focused and keep gaming more effectively throughout your gaming session. The MLG Phantom"s 132-millimeter temples, 25-gram lightweight construction and full rim frame are composed of stainless steel and are designed to generate proper strength and optical stability. Keep your glasses in place with the 16-millimeter nose bridge and adjustable silicone pads that help provide a dynamic fit.
