about six months ago, I started wearing shade three welding/safety glasses, styled almost like regular sunglasses, and my SEVERE eye issues are about 40% what they were due to this. I used to be almost completely blinded and suffer from migraines and a burning/itching sensation in my eyes if outside too long, not anymore.
downside, shade 3 interferes with colorvision, shade 5 makes red stop lights and brake lights INVISIBLE. you can use shade 5 in the woods but don't drive to the woods with them on unless you have to. I use nemesis brand. here is the link.
