The Epoch Eyewear Murphy is our take on a classic look. The ultra-lightweight full-frame is a great look for everyone. The arms wrap behind the ear to ensure a great no-slip fit. This is a favorite for active and every day wear. Mirror lenses are constructed by applying a reflective coating to a smoke lens base. These unique products deliver the same protection as smoke lenses but have the added benefits of enhanced color perception while reducing glare, all due to the addition of the color reflective coating. Ideal for full-sunlight, snow, and water-reflective conditions. Light transmission 10-13% depending on reflective coating applied. Smoke lenses are best for maintaining the true colors of what you're looking at. They block the most amount of light, which will help to reduce eyestrain if you'll be outside for an extended period of time. Epoch Eyewear is a Veteran owned and operated company.
