Prescription Shooting Glasses

[Captains1911]

I have been searching for prescription glasses with little to no luck. I would really like the ones where the lenses can be easily replaced, so that I could switch from clear, to grey for sunny days, and possibly even yellow. I have been to a few different eye doctors but none of them seem to be able to help, especially when considering my insurance. If anybody knows of somewhere online that I should be looking, that would be great. Thanks.

I have ESS glasses with inserts. Here's a link to the inserts from their web page.

I had the prescription lenses made at America's Best when I got my regular set.
