The Sunwraps(TM) are available in several varieties.
The most popular among pilots are the polarised blue blockers. They have a
yellow/orange appearance.
Two sizes, normal and large.
The are made of polycarbonate so do scratch relatively easily the
polarisation doesn't seem to be extreme and they block most but not all the
blue which lets your brain at least operate in colour not monochrome.
I also have a pair of prescription Ol Eagle eyes that I am happy with and
another pair of prescription sunglasses.
Polarised sunglasses may help by increasing contrast on LCD's (if the LCD
is organised the right way!).
My Suntiger clip ons don't get used as I can't operate in monochrome.
Fields of Salvation Jane don't show very well through Suntigers but the
Sunwraps let through enough blue to still see blue and purple.
For those with prescription sunglasses who now need bifocals I found a
product which sticks on to your existing glases to make them bifocals.
Called stick on bifocals. Search for this on Google. They work very well.
