  • Unusual uses for special requirements of certain occupational or recreational needs.  Such uses could be but are not limited to: use in swim goggles & dive masks to add magnification to allow easy reading of gauges, watch or a camera when you are not able to use your multi-focal glasses.
  • Use on welders masks. 
  • Use on motorcycle helmets.
  •  A Note for Divers: If you are going to use these in Dive Mask ONLY, you may order one strength down from your regular strength, as under water magnifies our vision by about 33%. This information should help some of you. Most of our customers still purchase their normal strength in the lenses so they can remove them and reapply them to their glasses once they've finished their diving adventures for the day. It is recommended to buy one pair for your dive mask and a second pair for your sunglasses. In a swimming environment especially, it may not be best, to try and peel the lenses off your mask and reapply them to your sunglasses. You may drop and lose one of the lenses on your boat or worse yet... in the ocean.  Formula For Use Underwater.
  • D-Segment Bifocal Lenses permit simulation of bi-focal lenses before Rx fabrication.  (For therapeutic trial of initial bifocal.)
One pair comes with two soft pliable, lightweight lens that are applied with tap water.
They are removable and reusable!

    I'm little bit angry, because i bought it here, and today i found it cheaper here: http://topamshop.com

    My wife and I both applied a single lens to our prescription single-lens dive masks. We expected to be able to read our underwater gauges and dive computers better. The lines in the fresnel lens were distracting and did not improve focus on objects held closely. We ended up removing the lenses and going out. We're very unhappy with return policy restrictions.
