Neodymium glasses , greatest eyeglasses color, I think you are talking about them. There is a glass studio called Cam Ocagi at Istanbul and when I went there , people were wearing these glasses to protect their retinas from radiation of hot glass.
I really loved the color ,I think I must find the seller. Second thing is the amber , real natural amber deep yellow glasses.
I will try to buy it when I visit Russia.
Thank you reminding me them.
