Totally my own fault for not thinking to bring sunglasses, but this afternoon I drove for about an hour and a half on the M5 southbound, and the glare from the low sun on the wet road was the worst driving conditions I've ever experienced. Obviously did all I could to mitigate it - visor down, sitting up as high as I could to minimise the white sky glare but it was horrible. My vision seems to be fine now, but my eyes feel like they're slightly burning (could just be psychosomatic?) and I'm worried I've done them some damage. Anything I can do now, or is it just a case of wait and hope for the best?
