Forget masks needing face fit and separate visors, etc. Check out PAPR (positive air pressure respirators) devices that use a pump to feed highly filtered air through a hood and over the face. More effective, much more comfortable and no need for face fit testing. If you need some contact points for these PM me. Chris (chris@enviroderm.co.uk)

I am assuming that you are wearing a face covering due to social distancing not being possible in the work envrionment that you work in. We have the same situation where some jobs require two people to work close to one another and face masks needs to be worn.

You can get some sprays which will stop the eye protection from fogging or as someone who wears glassess I would recommend putting some medical tape at the top of the mask securing to the face or pulling the mask up enough that the glassess sit over the mask (not always comfey).

In terms of hearing protection getting in the way, are ear plugs an option? This would depend on noise levels etc
