Glasses ???? These listings are for eyeglass and sunglass FRAMES only. Any lenses present are incidental and are not represented as prescription-free, plano, or of any specific optical specification. Used clear lenses frequently contain prescriptions or reading magnification. Sunglass lenses may or may not contain prescription tinting — we make reasonable efforts to identify this where possible but are not licensed optical professionals. No medical or optical advice is implied or provided. Buyers purchase with full understanding that lenses are used and unverified.
