...and who pop up on every thread on face mask exemptions to suggest them.
Nicola Sturgeon has just announced that from Saturday, visors cannot be worn alone in public places where face coverings are required and must be worn in addition to another face covering, as the Scottish government don't believe they offer suitable protection.
UK government guidelines currently state that a close fitting cloth covering is to be worn - no mention of visors.
There's also the fact that many who are exempt can't wear them anyway!
