Pratice makes tired eyes

[Scythe13]

Given how sunny and warm it was over the weekend, I wonder if this was "partly" due to bright sunlight??

I did think that, but I was using a yellow filter. I have always preferred the yellow tint, even as a kid, for sunglasses. Never had a problem with it in the past. I thought yellow tints were cool before Ali G made them 'cool' (imagine the flack I got wearing them when he was big! Not good). Never had a problem with them. The wife was wearing her sunnies when she wasn't spotting.

It was literally an eye-ache. Like muscular soreness.
