Same thing happens with me, by the end of a 30-40 mile ride encrusted sweat pretty much eliminates seeing. By doing the above the problem is much reduced. If you don't use a strap then get one and ride loose as stated.
The sweat beads on my eyelashes and when I blink they flick it onto the glasses and it forms a roost pattern. When climbing, I sweat buckets and glasses are useless.
