Now you can change your lens color for fun or function! Lenses are designed for the ILS style Doggles available in 5 sizes (XS - XL). Order according to the size Doggles that you own. Solid Black color is not transparent. Clear is great for night driving. Yellow if perfect for dusk or early morning. Go Joe Cool and get a mirrored set. How about a hot pink set for that special little girl? Or just replace any set that is too old or damaged!
