I cursed myself for not donning my sunglasses on this evening's ride home. It wasn't because the sun was blinding -- far from it. It was more to do with the insects flying about. No sooner had I negotiated all the horrible bumper-to-bumper traffic along The Strand (mental note, don't cycle this way home again, it's far too fraught and bloody slow) than a bug flew into my left eye and then bounced right on out again! And yes, it hurt, thanks for asking.
I'd forgotten about the dangers of cycling without protective eyewear. Tomorrow I'll be making sure I have my sunglasses on my face, rather than floating around in my cycle bag!
