Quoted from SDTMinSTL:I was...skeptical. I think anyone would be. In this day and age of amazon sellers flipping mass marketed imported polarized sunglasses on Amazon, why would someone pay $80 for a pair?
Well, I am here to say, I think they are worth it. Given the cost of invisiglass and its equivalents, dare I say, they might be a bargain. After receiving them, I did a little experiment and tried to find something similar for less. I couldn't. These aren't cheap ebay/alibaba/amazon 3rd party seller sunglasses with a logo on them. They are very light tinted(that is tough to find). Contrast is increased, glare is reduced and they are comfortable. I play with them every time now.
Maybe I am just obsessed with any edge I feel I can get, but I recommend them. Super bright LED flashers are no longer an issue, and neither is the "Haze" that used to be on my machines. Laugh at me if you must. Claim I am susceptible to being hood winked if that is what fuels you...but I enjoy mine, and the people that have tried them admit they are a benefit. I'm a believer.
Don't forget to purchase you head lamp light at the same time, I believe that you can get a discount when checking out with the glasses.
