Based on Serob Karamyan's advice (PhD in pharmaceutics,Yerevan State Medical Univeity Department of Pharmacology), relying on prototypes available in the market, we modeled special glasses that can be easily printed with a 3D printer, and the protective plastic membrane can be cut with scisso or with a CNC laser machine (if you have it at hand) from an A4 sized thick and traparent plastic). We posted the corresponding models in the Internet. We hope that it can contribute and help humankind in the fight agait the new coronavirus worldwide.
