Although I tend to avoid amber or any nonneutral lense color, Orvis's house brand glasses with bifocals are excellent for spot and stalk fishing. I ordered them with double strength bifocals to make bloodknot tying easier.

I have considered ordering grey polarized glasses for my Ranger Edge shooting glasses for hunting, but mostly I use Maui J's or similar quality, all with bifocals, but otherwise, uncorrected lenses. My only complaint is that they tend to be a bit too dark when consulting OnX or my Garmin collar gear.

Glasses for grouse, however, are a real hard one. Nothing seems perfect all the time, or even most of the time.
