Don't let your contact lenses take away from your flying. Apparently, extended wear can extend your flight training time. At first I thought my allergies were having an effect on me. Later in the evening, it felt like I had something in my eye. I took out my contact, and then bring on the water works all night long. Sunday afternoon, I took a trip to the emergency room. ER Doc thought it was a Cornea Ulcer. I went to an opthamologist today to find that it was an infection of the eye. Hopefully, I will be all good by next weekend. I missed some cross country training this weekend, and I probably will have a two week gap between flying last. Moral of the story, extended wear, shouldn't be extended if you value your eyes! Your eyes need the oxygen, and the contacts need to be cleaned just like any other contact.
