GIVE NEW VISION TO OLD GOGGLES
If you have goggles (new or old) that you can't find replacements lenses for, give a call to the folks at Pro Lens (800)776-5367. They stock thousands of replacement lenses and they're available for $14 to $25 each. Just provide them with the goggle brand name, model number (if possible) and lens tint color. If the replacement lens is available, they'll take payment via credit card and send the lens to you. They also offer mirrored lenses, prescription lenses, and new goggles from all major manufacturers as well.
