Good glasses wax
I saw Nerdwax a while back on Shark Tank, and the product looked intriguing to me since my nose isn't shaped to keep glasses from naturally sliding. I've used this a handful of times thus far, and I think the company has a good product. I have to reapply the product every couple of hours to keep the grip, which is what the company states on their site. I do think it is bit expensive for what it is ($10 a tube + shipping), but if you wear glasses daily and have the issue of slippage, it is one of the better products on the market to help the problem and it is probably worth the expense. I usually wear contacts, but now when I wear my glasses at night, I try to remember to put Nerdwax on to improve my comfort.
