How do Contrast HEV TheraSpecs work?
Contrast HEV™ helps you see the world in higher definition. By filtering the high-energy visible light below 455nm that our eyes don’t focus well, this lightly tinted yellow lens brings greater visual contrast and sharpness for your favorite activities. If screens or bright lights give you visual discomfort, we suggest making Contrast HEV part of your light management toolkit.
Contrast HEV is also light enough that it is legal to wear while driving at night in most locations.
*TheraSpecs Contrast HEV transmits approximately 90% of all light, making it compliant with traffic laws in most places for night driving. However, users are responsible for ensuring their use complies with all applicable traffic regulations and that road lighting is sufficient for safe use. Always drive responsibly and remain attentive to the road and lighting conditions, traffic signals, and other vehicles.
