Thanks, Andy.
Mmmmm......no, getting to the range once you've had the eye drops in to dilate your pupils leaves you with blurry vision for about six hours wasn't going to be on the cards. Nice thought, though.
Scans etc didn't reveal anything sinister, so they think some "abrasion to the cornea" has occurred and should settle. Vision has cleared a fair bit since Friday. However, when wearing my glasses, it's almost like the right is out of focus. Hopefully this will settle soon. But at least they couldn't find any real naughtiness going on, which was reassuring.....
