James Ayscough (died 1759) was an English optician and designer and maker of scientific instruments. He was apprenticed to an optician named James Mann from 1743 to 1747. James Ayscough became known for his microscopes. His shop was in London between 1740 and 1759. Around the year 1752, James Ayscough introduced spectacles with double-hinged side pieces. Although he made clear lenses, he recommended lenses tinted blue or green to treat some vision problems. These spectacles with tinted lenses are believed to be the precursors to sunglasses.
