PMMA lenses are made from a transparent rigid plastic material called polymethyl methacrylate (PMMA), which also is used as a substitute for glass in shatterproof windows and is sold under the trademarks Lucite, Perspex and Plexiglas. PMMA lenses have excellent optics, but they do not transmit oxygen to the eye and can be difficult to adapt to. These (now old-fashioned) “hard contacts” have virtually been replaced by GP lenses and are rarely prescribed today.
Contact lenses and their concept have been around for much longer than most people believe.
Along with many other modern day conveniences, Leonardo da Vinci envisioned the concept of contact lenses in 1508. In 1636, Renee Descartes took this further by sketching a protruding contact lens. Later, in 1801, a scientist named Thomas Young became the first to wear a contact lens, which was secured to his eye with wax! More details on Korean circle lenses …
Daily wear is not to be confused with daily disposable. Daily disposable refers to contact lenses that are meant to be used once and discarded daily. Daily wear is worn daily but not suitable for overnight wear and must be cleaned and removed before sleep. Wearing lenses overnight increases the lens wearer’s risk for eye disease. Therefore lenses are often replaced on a weekly or monthly basis.
Proper cleaning and handling of weekly and monthly lenses is critical to keeping eyes healthy. Lens cleaning is not just an option, but a must in the world of weekly or monthly contacts due to the health risks bacterial deposits may present.
Extended wear lenses. You can wear extended wear soft contact lenses while you sleep, but they must be removed for cleaning and disinfecting at least once a week. It’s important to be cautious with overnight use, though, since it increases the risk of eye infections.
Disposable lenses. These lenses are typically more expensive. You wear the lenses during the day and remove them at night. They don’t need to be cleaned or disinfected. You use them for the recommended time frame – such as daily, weekly or monthly – and discard them. You might consider disposable lenses if you wear contacts only occasionally, you can’t tolerate disinfecting solution or you place a premium on convenience.
Avoiding complications : Practice good hygiene. Use clean hands when handling your contacts. Wash your hands with soap and water, rinse and dry them with a lint-free towel.
