Who invented soft contact lenses and in what year

Other reports say that it was actually Adolf E. Fick and Edouard Kalt, a Paris optician that created and fitted the first glass contact lenses for correcting vision problems back in Since these large lenses reduced the supply of oxygen to the cornea significantly, wearers would only tolerate them for several hours, and they never gained widespread acceptance. William Feinbloom, a New York optometrist, introduced new scleral lenses in made of a combination of glass and plastic that were considerably lighter than previous glass-blown contacts.

Kevin Tuohy, a California optician, introduced the first contact lenses that resembled the modern contact lenses back in In , English astronomer Sir John Herschel proposed the idea of making a mold of a person's eyes.

Such molds would enable the production of corrective lenses that could conform to the front surface of the eye.

But it was more than 50 years later that someone actually produced such lenses, and there is some controversy about who did it first. Some reports say German glassblower F. Muller used Herschel's ideas to create the first known glass contact lens in Other reports say Swiss physician Adolf E.

Fick and Paris optician Edouard Kalt created and fitted the first glass contact lenses to correct vision problems in Early glass contact lenses were heavy and covered the entire front surface of the eye, including the "white" of the eye the sclera.

After almost a decade of improvements, Bionite soft lenses were made available in the United Kingdom. Unlike hard contact lenses they could be worn throughout the day by most users with relative comfort. Food and Drug Administration to sell their soft hydrogel lenses. They proved to be incredibly popular, helping to kickstart the modern age of contact lenses.

Over time, the hydrogel framework for contact lenses was expanded and improved upon. In , gas permeable extended wear lenses were released. Gas permeable GP lenses are made of firm, durable plastic that transmits oxygen. Because they have no water content, GP lenses are less likely to harbour bacteria than soft contacts. These soft lenses overcame hygiene problems by simply allowing the user to throw them away after use.

The disposable contact lens was a huge success and remains the most popular type to this day. The history of contact lenses. Photo by Giammarco Boscaro on Unsplash Compared to glasses, contact lenses are a relatively modern invention.
