These eyeglasses reduce eyestrain that results from viewing a computer screen for extended periods. The glasses combat the painful symptoms of Computer Vision Syndrome--at least 90% of the U.S. computer-using public is affected by the syndrome according to the National Institute of Occupational Safety and Health. The yellow-tinted polycarbonate lenses' proprietary tinting blocks out 65% of blue light, a wavelength that reduces the sharpness of objects, leading to eye fatigue, tired or sore eyes, and the chance of headaches. The lenses protect against UV radiation up to 400nm, protecting eyes from harmful neon and halogen light sources. An inner anti-reflective coating on both the inner and outer side of the lens decreases the glare from overhead fluorescent lighting. Intended for use by those who wear contacts or do not require corrective lenses. Lightweight plastic frames. Includes hard 6 1/2" W x 2 1/2" D x 2" W storage case. (1 oz.)
Improving Accuracy: Yellow tinted lenses preserve color recognition while improving your percentage of depth perception and contrast.
Higher Protection: The lenses provide protection against UV radiation up to 400nm. The UV absorbing lenses protect eyes from harmful neon and halogen lights.
Less Fatigue: High definition lenses block out 65% of blue light. This reduces the sharpness of objects which cause eye fatigue, tired or sore eyes, that can lead to headaches.
Greater Comfort: Anti-reflection coating decreases computer glare and overhead fluorescent glare.
Recommended for Driving: Enhanced color recognition provides the wearer with improved safety and faster recognition of potential hazards on the road, especially at night. Also, the reflection of street lamps and headlights on the lenses are virtually eliminated.
High Durability: Anti-reflective coatings enhance the quality and extend the lifetime of the lenses by providing superior scratch resistance, durability and resistance to dirt and water. Meets ANSI Z80.3-2001 and CE EN1836 standards.
