The Phonetic Eyewear Casey frame is a pair of ready-made computer glasses designed to reduce digital eyestrain and fatigue caused by viewing digital computer screens and/or working in artificially lit office environments. According to a study by the Vision Council of America, nearly 70% of adults experience some form of digital eye strain due to prolonged use of computer devices. One of the causes of digital eyestrain is the excessive violet/blue light emitted by digital devices and today's fluorescent lighting. The lenses used by Phonetic Eyewear have a proprietary coating that deflects a portion of the violet/blue light thereby reducing eyestrain. Wearers notice a reduction in glare and an improvement in visual contrast. Phonetic Eyewear lenses are prescription quality and made from a 1.56 index lens material and block 99.9% of UV light. Other computer eyewear makes use of either yellow or amber tinted lenses that absorb blue light while Phonetic's technology actually deflects the blue light off the front of the lens. Phonetic's clear lenses are more visually appealing and are the preferred solution for college students or those working in a professional office environment. Other advertised computer eyewear often has only a basic anti-reflective coating which does not deflect the unwanted blue light. Phonetic's lenses included a hard coating to prevent scratching. The Casey frame is a unisex design made from high quality acetate with metal accents on the temples and fits most faces. The frame dimensions are 52-17-140mm (eyes-bridge-temple). Also included is a neoprene protective case and microfiber cleaning cloth.
