I love these Sunglasses!  If I had my Camera here, I'd show just how exactly they fit my Glasses.  The ONLY downside is that the black flippy part in the center is rather large and obvious, looking a little funny.

My eyes are fairly sensitive to bright days.  I wear Sunglasses outside even when it's overcast or raining.  (And living in northern Oregon, that's most of the time!)  They work very well AND really do seem to enhance (sharpen?  crispen??  clarify???) what I'm looking at as I drive.

Even on Sunny Days, they work well.  We haven't had many of those yet.  But when we have, I haven't found it necessary to replace them with my darker Sunglasses.

They seem to be very sturdy.  I purchased 2 pairs since I'm "always" losing / misplacing my Sunglasses.  But I'm going get a couple more pairs before too long.  Just in case these disappear!

This is one of those times where you get what you pay for.  They ARE fairly expensive.  But they're also worth every penny of it tom me!
