I know this is slightly off-topic but this thread seems like the right audience.
Last summer, a top cadet wore contact lenses during the last FTX. He got an infection and a corneal ulcer. The defect has not (and won't) heal. When you have a corneal defect, there's a very good chance it'll affect your vision. The cadet can't be corrected to 20/20. In fact, the cadet now requires rigid permeable lens to have some visual acuity in the eye. The other option is corneal transplant surgery to maybe get to 20/20. The Army won't waiver someone with a corneal transplant or requires contact lens (in this case the cadet requires the rigid, permeable lens). The cadet will probably not meet commissioning standards. As many people know on this forum, wearing contact lenses in the field (and while deployed) is a no-go. The cadet wore contacts anyway.
This isn't a lesson specifically about contact lenses.
My point is please pay attention to the guidance and directions the cadre and leadership when you're at Camp. The guidance is there for a reason. The guidance is there to keep everyone safe and healthy and allows cadets to get the training they need. Please enjoy camp. It's tedious. It might be monotonous. It'll suck bad when it's 100 degrees outside or when it's raining. But remember, thousands of other cadets have completely it, so get the most out of it and things will end up fine.
