I'm 25 and have never had a vision exam before. I work on a computer for about 10 hours a day and I noticed my distance vision has declined. I'm having trouble reading exit signs on the highway until im up close and shooting with iron sights is possible but far from as good as it could be. I think maybe the eye-muscles for distance sight have deteriorated from lack of use. I want to get some eye glasses but I don't know anything about it. I also have a few "eye floaters" and they worry me so I want a complete and thorough eye exam. I don't really trust the Mall or Walmart Vision place for a thorough exam so I'm not sure where exactly to go? Optician, Opthamologist, Optomotrist?? Do I need to ask for a special pair of glasses for shooting? Like protective shooting glasses with prescription lenses?
