RE: Sunglasses
I have the same problem with the tree lines hiding my plane at the transition from a blue background to the tree line background for just a moment.
Unfortunately, I broke my sunglasses earlier this week. I was just putting them on my head and the earpiece broke right where the plastic meets the rubber boot. I plan to call the company on Monday and see if they'll send me a new earpiece or if I'm just out of luck with four sets of lenses and a broken frame.
I'll let you guys know how the customer service is.
