Fashion contact lenses can now be for everyone thanks to prescription novelty contact lenses. If you are into makeup artistry either as an amateur or professional then white coloured prescription contact lenses are perfect for creating eerie makeup looks. White lenses are the ultimate scary lenses because we are used to seeing colourful irises. Become a super freaky Halloween character or use for your next photoshoot. If your glasses are cramping your style then why not ditch them for a night and get yourself a pair of prescription fancy dress contact lenses. Several tech companies are also developing contact lenses that can deliver medicines via the eye.Are you getting ready for a fancy dress party? Step your costume game up a notch with a pair of white prescription contact lenses. For example, lenses in the future may have a special function that allows them to zoom in on objects or make texts easier to read. They fit perfectly on the eye and therefore feel very comfortable.Īnd in the future, so-called 'smart contact lenses' may come onto the market. Comfilcon A contact lenses are soft and flexible. For example, it is used in the production of the popular Biofinity lenses. Comfilcon A is a silicone hydrogel material. Daily contact lenses made of silicone hydrogel have become increasingly popular because these lenses are so easy and hygienic to use.Ĭontact lens technology has continued to evolve with new materials such as Comfilcon A. This means that lenses are very flexible and fit well on the eyes. Lenses made of silicone hydrogel contact lenses absorb even more water than hydrogel lenses. This material allows up to 5 times more oxygen to pass through to the eye. In the late 1990s and early 2000s, silicone hydrogel became the most popular material for making lenses. Contact lenses had become so light, with high water content and very oxygen permeable, that under the guidance of an optician, they could even be worn at night while sleeping. For example, extended-wear lenses came to the market. Spectacle wearers who would not normally wear lenses could now wear lenses for special occasions or during sports.ĭuring the 1980s, there was also progress in the materials used for contact lenses. Dailies became more convenient and hygienic to use. Later, multifocal lenses and toric lenses for presbyopia and astigmatism came on the market.ĭaily contact lenses were introduced in the 1980s, which changed the way people viewed contact lenses. In the early 1970s, Bausch & Lomb released the first commercial soft contact lenses made of hydrogel lenses. Fun fact: using his son's toy construction kit, Wichterle produced the first four hydrogel lenses.Īs production technology became more advanced, contact lenses became thinner and thinner. Together with his colleague Drahoslav Lim, they created a material that absorbed up to 40% water, which was also transparent and could be moulded into a comfortable lens shape. And as its popularity increased, the technology used to make the lenses became more sophisticated.Ĭzech chemist Otto Wichterle made a huge breakthrough in making the first hydrogel lenses. Thanks to this comfortable lens, contact lenses became a lot more popular in the 1950s and 1960s. The lenses moved during blinking, allowing more oxygen to enter the eye and allowing the lens to be worn longer without irritating. His lenses were small and made of a non-porous plastic called polymethyl methacrylate. Kevin Touhy took lens design to the next level. This made the lens a lot more comfortable. Not only was this a lighter lens with better oxygen permeability, but the plastic was also better for the natural tissues of the eye than glass. A glass portion covered the cornea while a plastic shell sat on the white of the eye (sclera). In addition, glass is not very permeable to oxygen anyway, so this design made for an uncomfortable and potentially dangerous contact lens.Īmerican optometrist William Feinbloom developed a contact lens that combined glass and plastic. These glass lenses felt quite heavy on the eye and they covered the entire eye so no moisture could get to the eye to hydrate it. While these lenses were useful for correcting vision, they did cause problems. But whoever it was, both prototypes were made of glass and covered the entire front surface of the eye. It is disputed who was the first to make the first glass contact lens. His idea became a reality later that century. He made molds of the human eye and then used these molds to design the front of corrective lenses. As expected, this didn't catch on as a new trend!Īnother British scientist, John Herschel, had an idea closer to the contact lenses we know today. He used wax to glue the tubes to his eyes. He reduced the length of the tubes to make a lens about a quarter the size. Scientist Thomas Young put Descartes' ideas into practice by making lenses using his proposed technique.
