Good info! I'm generally a dollar store sunglasses wearer, but I'll be sorting through all of this and buying myself a really good pair of sunglasses this week! I just had a very scary thing happen with my vision after shoveling snow last Sunday in the sun for 6 hours with no sunglasses. Diagnosis: snow blindness. I had cataract surgery last April and so have implants with UV protection, but obviously that doesn't mean I can go without sunglasses. BIG wake up call.
