Designed for the cyclist, the runner, and the endurance athlete, the Altar Photochromic Sunglasses are the latest example of Tifosi's decade-long dedication to its mission. Streamlined from front to back, the contoured frame of the Altar is like a missile designed to cut through the air. Adjustable nose pads feel comfortable against the bridge of your nose, and soft arm pads sit softly against your temples. Just above each eye is a small frame cutout shaped to move air behind the lens so it can carry moisture away from your face and save you from foggy vision. The photochromic lens is a small miracle of engineering. Variable tint technology allows this lens to automatically adjust to changing light conditions. In bright, direct light the tint grows darker and in dark, overcast conditions, the tint becomes much lighter. You'll never have to squint at the sun or strain your eyes to see in the shadows, and you'll never have to swap lenses again. The advantage of photochromic technology is massive, and when coupled with the frame vents, you're treated to the most dynamic, fog-free optical experience Tifosi sunglasses have to offer.
