After years of buying $10 (or less) sunglasses, I bit the bullet and bought these.  They are, without doubt, the most comfortable pair I've had and are attractive on my face (no small feat).  The polarization is fantastic and these glasses do not distort my vision like so many others in my "give away" box.  I very highly recommend them but will mention that, if you have a very narrow face they may be too large and they only come in one size.
