My older sister has macular degeneration, and bright light hurts her eyes and she sometimes needs to wear sunglasses even inside her home.  So, I sent her a pair of these sunglasses and she loves them.  With winter coming she will have even more use for them when the sun reflects off the snow.  She is happy.  I, too, am happy with my pair.  I like that they hug the head without what I call pressure pain from the portion which fits behind the ears.  I must wear prescription eyeglasses, and these sunglasses have a "shelf" that rests on top of my glasses and this holds them beautifully in place.
