With having to wear a mask almost all the time outside I would like to find a better antifog spray for my eyeglasses. I used to get it at walgrens or CVS. They dropped the antifog part and raised the price several years ago. I would like to buy a decent size bottle not the 2 mil ones I see online. Can I just put a few drops of ca windshield rain-X in my existing spray? I think the antifog stuff is basically silicone oil in water.
