Eyeglasses from Doctor M from the Trice brand. The lenses change to sunglasses with the sun, and they also have protection from the rays of mobile phones and TVs. Special orders. I've had them for less than a year, approximately 10 months. The reason for selling is that I had refractive surgery, praise be to God, and I no longer need them. Type: Prescription Frame Material: Metal Lens Material: Glass Lens Features: Anti-Reflective
