I recently went to a monthly club match about 1.5 hours away from where I live. The day before I did what most all of us do; clean gun, check parts, mags and rig, empty range bag to make sure I have everything, reload range bag accordingly. I had been shooting indoor matches in the weeks prior, so my sunglasses were not in my bag and I didn't think to put them in with my other glasses. We get to the match (hammer down at 9am) and I see that all 8 bays are facing directly into the sun. I think to myself "no worries, I've got my sunglasses" (no I don't). After realizing I left them at home, a friend of mine on my squad offers to let me wear a pair of his Hunters HD Gold glasses, only one catch...they're prescription. I'm not one to turn down a challenge, so I put them on 15 mins prior to start to make sure I can see and move safely. I'm g2g, so I then shot all 8 stages without a hitch.
(disclosure: This was the day that I learned that I need glasses)
