DHC | History, Entertainment & News on Instagram: "In 1948, contact lenses were made entirely from hard plastic, PMMA, a major upgrade from the fragile glass models that came before. These early lenses were the first to cover only the cornea instead of the entire visible eye, thanks to Kevin Tuohy’s groundbreaking design. They didn’t let oxygen pass through, meaning all oxygen to the eye had to come from blinking. As a result, people could only wear them for a few hours before discomfort set in.
