You like the idea of wearing contact lenses but shudder at the thought of putting them on every morning and taking them off every night? The solution to your problem could be extended wear contact lenses, which can be worn from seven to 30 days without removal.
As EyeHealthWeb.com explains in its article on the subject, extended wear soft contact lenses are made from hydrophilic polymeric materials that are highly oxygen permeable. As a result, more oxygen reaches the cornea, allowing the lenses to be worn for longer periods.
Extended wear lenses that employ more advanced technology are made from silicone hydrogel materials. They have several advantages, most notable among them being their ability to let through up to six times more oxygen than disposable contacts. Compared to regular soft lenses, more advanced extended wear contacts retain their moisture better. This makes them a good choice for people with dry eyes and a desire to swap their glasses for lenses. In addition, protein and bacteria build-up on these contact lenses is reduced thanks to their special biocompatible surface treatment. This is an important advantage because such build-up increases the likelihood of eye infections.
Extended wear contact lenses can provide great convenience for significantly nearsighted people, who must always have their glasses within reach. But convenience should not come before eye health, so it is extremely important to remember that wearing such lenses requires extra care. It must not be done without regular supervision from an eye care practitioner and instructions must be followed without fail.
