I always read product reviews, on Amazon, before I purchase most products(and I always select the highest reviewed products, when possible), and this worked out well for me with these sunglasses. Several reviewers noted that this particular model fit larger heads, and since I qualify(in spades!), I bought these.  Pleasantly surprised that they actually fit, I wear them everyday. They're lightweight, and don't gouge out my nose, if I wear them for extended periods of time. The only, as yet minor, complaint I have, is that the top fits snug up against my eyebrows. If I'm exercising(either biking, or walking), I definitely have to wear a head band, as the sweat runs right into my eyes. I would also like it, if the lens came down a little lower, as I feel I'm not that well protected from reflected glare from below.  I would definitely buy this product again, however.
