Neither Hersey or West have you drop your pants. Hersey has an eye chart on a wall and West has one of those little viewers. As far as lenient, I wouldn't say either will let you blow it off. West's nurse is pretty laid back and the office is less "industrial" than Hersey's. Hersey works out of a small clinic while West is working out of a hangar with a couple offices and an bathroom. The enviornment is pretty laid back for West.
I like West better and that's why I've stuck with him. But both are pretty low threat and nothing to worry about. If you're breathin', you should be fine...
