Round frame made of clear plastic, with a simple and stylish design. The lenses were originally intended to be photochromic, and I had them changed personally. They are non-prescription photochromic lenses. They turn a brownish-gray color in response to ultraviolet light. - Brand: SATCHMO - Model Name: Eyeglasses - Frame Material: Clear Plastic - Lens Shape: Round - Design: Simple and Stylish Thank you for viewing.
