I wear a visor because it can take as little as 45 seconds to start hyperventilating in a mask.
Although it only took 3-4 minutes to start hyperventilating under the visor in the time it took to collect DS's inhalers in the pharmacy. Kind of ironic gasping for breath while holding someone elses inhalers.
As there's no way I can wear a well fitted, effective mask, it's all a moot point.
It's no less effective than a lanyard, and so far 100% at repelling arseholes who'd have no issue in creating an illegal row with a small, young, fit woman who just physically can't cope with breathing in her own recycled air. Firtunately the law is on my side.
I'm relieved when staff wear visors because I can make eye contact and lip read and communication is much easieŕ.
No fucking way am I ruining my health and my family's quality of life by needlessly being a prisoner in my own home to appease someone else's illegal and irrational paronoia about masks/ virus.
