I humbly suggest this has nothing at all to do with the OP's bino, and more to with the OP's tear-ducts. I have a condition called 'watery eye' in my left eye only, and occasionally find the same...on cold mornings, one ocular fogs a little extra. Younger BF-ers take note...as you age, things turn to sxxt. Now I'm going to check a mountain-biking forum, and have a real fight with someone about stuff I know nothing about<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />.</p></blockquote><p></p>
