We typically associate sunglasses with summer, but the truth is that your eyes need protection in the winter months, too. Right now, REI is in the midst of its Member Days sale, which includes huge savings on sunglasses that you don’t need to be a member to get. If you’re looking for a really budget-friendly pair, Blenders Eyewear delivers a surprising set of features for less than $40. The polycarbonate lenses are polarized and provide 100 percent UV protection. That’s important in winter with snow or when you’re on the water.
