I agree. But services should also be able to require that you remove those types of glasses to use their service.

In that case, if you ride the bus for free, you see the ads or you don't ride the bus.

Blind people shouldn't be allowed to ride the bus then?

Blind people would be fine as they wouldn't be wearing the glasses. Being physically unable to see the ads and purposely hiding them, are two different things.
