At iPOP, we believe in making your shopping experience as convenient as possible. That's why we provide measurements for our sunglasses. When we measure the width, we take the distance from the inside of the left hinge to the inside of the right hinge - this usually corresponds to the width of your face.
As for the height, we measure the entire frame from top to bottom. We want to make sure you find the perfect fit for your face, so you can rock your new shades with confidence!
