I wear contact lenses when I shoot and hunt....last year I took a break from lenses, and hunted with glasses and vowed never to do that again!

I use a product called Z wax, that I like a lot. it comes on a little vial or a spray bottle

Baby shampoo mixed in salt water works great

Thanx for sharing

Used the cat crap...ordered the spray used it over a dozen times and has yet to prevent the fog. Every time if fogs right away.

Eye surgery works, but how many times while walking to your stand in the dark, did a branch slap your face.   I have tried most of theses ocer the years, and most work for a time, but need constant application
Good thread with some new ideas

Just one of several reasons I went to contacts 30 years ago and at 63 I'm still enjoying them.  Don't know your situation, but certainly worth considering.

I have and use contacts but with a stigmatize the contacts aren't as comfortable and on them all day sits my eyes get dry and heavy and it always makes me tired so I prefere glasses.

Pledge furniture polish.
There's a lot of ideas in this thread i never heard before! I may have to try a few....
