Our lens technology. Each lens is cast from platinum-cured liquid, which sets without giving anything off, so nothing clouds the lens. It holds to your glasses with a drop of water instead of glue, and peels off clean.

The platinum-cured lens clings to smooth lenses on its own. A drop of water lets it glide into place and pushes out the air. There is no adhesive, so it peels off clean.
