I know everyone is not effected by this, but being and old man with glasses. When the STHF and we are back to basic, I know one of my weakness will be me wear glasses. Out in the elements and just breakage is things I have to take as a real threat. I have a extra pair for one thing but we have no way of know how long things will be. I know some will have contacts that will have the same problem too. Any ideas.
