I love these York Warby Parker aviator style eyeglasses so much I purchased the same pair in my new prescription. The ones listed are prescription -3.75 each eye with high index thinner lenses and transition to gray in the sun. Eyeglasses are in excellent used condition. I also had the nose pads replaced recently. Will include case with minor damage as shown in photo. Ask questions below, open to offers!! Thanks! Happy shopping.
