This threads purpose is to start a list of sights that we can look at and if we do purchase items evaluate them for others.

This sight features breath shields for slit lamps and pupilometers.

I'm going to suggest for $13 our dispensary try the pupilometer shield.

I'm also having fun using cheap clear page protectors from Staples. Modified with scissors and attached with tape I made one for the pupilometer that will serve its purpose for now.
