LotuTec coating

Carl Zeiss Optical, Inc. takes great pleasure in introducing for the first time on its sports optics products, a highly effective water-repellent coating - LotuTec. With LotuTec, problems caused by raindrops, dust, smears and fingerprints are things of the past. LotuTec coating is named after the Lotus leaf effect. It is a super-smooth coating for anti-reflective coated glass surfaces which repels both water and oil, causing both to form spherical beads which run or wipe off with ease. If you are caught in a heavy shower and your lenses get drenched, a shake removes most water and a gentle wipe leaves the lenses spotless. Oils from eyelashes or salts from sweat, even sunscreen and fingerprints, come off cleanly without smearing. In addition, the LotuTec coating is extremely durable and resistant to abrasion. Light transmission through the lenses is not affected by the extra protective coating. Clean lenses give the best view, and with LotuTec coating, nothing could be clearer.
