No, if the true litmus test is to be applied, do the following: Run on your tread mill for 20 minutes and get really good and sweaty (I'd recommend you run 20 minutes outside, but I see its only 14*F in Riverton, which is nearby you, with a windchill of 4* F) so you'd probably freeze your windpipe. Wait! Before you start running, put some sunscreen on your face particularly just below your eyes, and when you've finished "running" and are really sweaty, take off your shirt and squeeze it out on the eye lenses. Then push the eyecups all the way down and get your eyes as close as you can and see if you can get your eyelashes to touch the lenses and while you're at it, rub your sunscreen covered cheeks on them too.After that, take your sweaty thumbs and squish them on both objectives. Zeiss says that LotuTec lenses are:Repels oils from eyelashes or salts from sweat, even sunscreen and fingerprints. If your lenses are LotuTec coated, they should be clean as a unblown whistle, but maybe a little smelly. If you are still not sure, get a Brillo pad and rub it over the lenses. Zeiss says that: In addition, the LotuTecTM coating is extremely durable and resistant to abrasion.So Brillo away! OTOH, if after all that, the lenses are wet, oily, fingerprinted, and scratched, well, you better get yourself a LotuTecTM coated pair! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Let us know how you make out.
