Poor or degenerative eyesight is a real hindrance. Eyesight that is bad usually gets worse. When the SHTF are optometrists really going to be an option? Scopes are fine but do they correct bad vision? I had always figured that basic, iron-sight guns would be the guns that lasted the longest. Iron sights are difficult to use if you have poor vision and don't have the proper corrective lenses. Some people I know have to have a new set of glasses every 2 years. What are your thoughts for those with poor eyesight for the long term when the SHTF? I don't know jack about optometry but is this an art that will be available if there were no electricity or organized society?
