An Israeli manufacturer just introduced the new “Blury Glasses” in the charedi communities all over Israel.
The glasses are designed with a special feature that it blurs out anything that is beyond 7-8 feet. The porpuse of these glasses are designed so one cannot see immodestly-dressed women.
For men who already wear regular glasses, the company offers stickers which can cover the lenses to create the necessary blur.
