Hold on to your glasses- right where it should be with Nerdwax’s grip wax. Nerdwax is an anti-slip eyewear retainer that can easily turn any kind of glasses to not slip. It works by creating friction between your eyewear and skin, keeping your glasses in place. Simply wipe surface oils off your glasses and apply them directly to glasses. It lasts 1 hour to all day depending on how much you apply.
