here in Australia the big issue is glare, particularly as you reach mature age.
Having my presctiption cut in polarised lens material (grey or tan) resulted in a huge benefit except if I needed to see the mirage movement through my scope.
I found that the degree of polarisation correlates with the degree of tint in the lenses & that resulted in a downside as most available here are 75% polarised. However, you have a far greater access to polarisation grades Statesides - the buggers just wouldn't sell individual sets of blanks to individual Aussies.
