Oakley Monster Dog Sunglasses Activated by Transitions

The Oakley Monster Dog Sunglasses Activated by Transitions feature durable, lightweight O Matter frames and shatterproof lenses that get lighter or darker depending on outdoor light conditions. Whether you kick back on the beach, play Frisbee in the park, or walk your dog around town, these nylon and polycarbonate frames feel comfortable on your face and shield your eyes. Monster Dogs lenses filter out all ultraviolet rays and curve to match the contour of the human eye, so your peripheral vision isnt distorted. The transition lenses, which UV rays activate, grow darker in direct sunlight and lighter in overcast conditions.
