I wore glasses from age 3 on until I was about 40, and no longer needed them. I would say that wearing glasses does not reduce the frequency one touches the eye or the corner of the eye. Glass wearers still reach up and rub the eye if it itches, or one has glop in the corner of the eye near the tear duct.
I do believe taking a quality vitamin/mineral supplement will help reduce the threat of being infected with COVID. Americans are suffering from deficiencies in many different nutrients. Our food has become crap over time with little to no nutritional value. You must take vitamin and mineral supplements to remain healthy and prolong your life.
