You are purchasing 2 pair of Epoch 1 Sunglasses with Black Frames. One pair has an amber lens and the other pair has a smoke lens. Epoch 1 is a classic, sporty frame featuring co-injected inlaid rubber that provides a non-slip fit comfortable for all day wear. The inlaid rubber not only optimizes comfort, but also improves the overall strength of the frame. Lenses are shatterproof polycarbonate and block 100% of UVA & UVB rays. 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. Amber lenses, also referred to as copper, brown or "HD", block blue light which helps to add depth perception. They are good for low-light conditions and block less sunlight than the smoke lens.
