Quality shades
Color: Blue Tortoise Dark Grey/Dark Grey, Size: 54/17/145
I need Rx in my shades for reading. I bought these thinking I can get away with wearing regular sunglasses but not a great idea on my part. Little too foggy. I do love them nevertheless and will gift them. They are sturdy and well-made.

I love sunglasses and this ones are so pretty. They have this blue-brown combination that it’s just perfect. They are not too big and not too small. I love them!
