Many people looking for moisture chamber glasses assume that in order to work properly the protective gasket needs to completely seal your eye sockets all round.
Actually that's not typically the case.
The optimum result is normally achieved with glasses that restrict airflow significantly while leaving a small fraction of the air to pass across the lenses, so as to reduce the potential for them to mist up.
You may wish to order two different frames from us to see which works best for you, because as discussed in an earlier post, the shaping of the different 7eye frames can be quite face specific.
If you need any advice, we are happy to provide it by email (firstname.lastname@example.org) or phone on 01392 411363.
