How Some of the First Plastic Contacts Were Made


The idea for contact lenses dates as far back as Leonardo da Vinci and René Descartes, but the idea of invisible vision correction couldn’t really take off until plastics became widely available. In the 1930s, doctors began manufacturing lightweight, unbreakable plastic lenses to replace the now-terrifying glass contacts of the 19th century. A newsreel called “New Look in Glasses,” unearthed in the film archives of British Pathé, shows exactly how involved the process of creating these early plastic contacts could be. The footage, which never aired, is from approximately 1948. 

The doctor anesthetized the eye before pouring it full of plaster to make a mold, a sight that to the non-initiated, looks more like a horror movie than a medical procedure. The mold was then used to create a custom plastic lens. These hard plastic lenses, covering not just the cornea, but the entire eye, could only be worn for six to eight hours at a stretch.

“Contact lenses: invisible, and comfortable,” the narrator intones. And expensive. The film reports that in America, these lenses cost  ‎£75—adjusting for inflation, that’s about  ‎£2620 today, or more than $4000. Ah, the price of frameless vision!
