> then the cheap mask help a lot when people wear them. Are there any reliable and conclusive studies supporting this?

  There are not even any reliable studies showing that surgical masks help during surgery. The problem with public health agencies is that, apparently, if they don't have an RCT they immediately jump to make the worst possible decisions. So try not to do the same thing.

      The kind with a bendable bar or tape at the top for your nose don't affect my glasses. Anyway, you're going to run into the same problem doctors' advice has, where everything not required is forbidden. If a 100-year problem like a pandemic comes up, try some unproven precautions, it's better than not doing anything until it's mandated.
