Specific recommendations on Yelllow Lens glasses
I'm interested to purchase a pair of Yellow Lens glasses, but searching here didn't yield many results. The information in Mark's books didn't really seem sufficient to choose a pair (aside from safety glasses or smithoptics), but what's the difference? What are the benefits of a more expensive pair etc.
So, I'm looking for recommendations and maybe a bit more of an education on the most beneficial glasses.
I want to start wearing them at night to help combat my eye strain, which is particularly bad at night.
