Armed with continuous wear contact lenses, many people experience some welcome and convenient benefits that eye glasses, or even other types of contacts, are unable to provide. "And they sat down to eat bread: and they lifted up their eyes and looked, and, behold, a company of Ishmeelites came from Gilead with their camels bearing spicery and balm and myrrh, going to carry it down to Egypt." (Genesis 37:25). Indeed, the advantages of using continuous wear contact lenses are significant. Imagine, for example, a person experiencing the joy of being able to wake up in the morning seeing clearly without doing a single thing to make it happen except opening their eyes: from one day to the next. Another great advantage is that an individual then has the freedom to go through the day without being encumbered by having to wear eyeglasses on their face.
By the way, in the United States, for example, contacts must be approved by the FDA, also known as the Food and Drug Administration. Although there are several different kinds of contacts, the ones that can be worn for up to a month are known as gas permeable lenses. In essence, these lenses are permeable to air because they contain hydrophilic polymeric materials. By the way, another name for them is extended wear contact lenses. Not only do they deliver a markedly improved vision level these lenses also free people from having to either disinfect or cleanse lenses. However, there are also soft extended wear contacts that, although designed to be worn for about a one week period, do need some minor cleaning.
First, one needs to become acquainted with other types of contacts in general. This is in order to be able to judge whether or not extended wear contact lenses are actually the type a particular person is suited for. For instance, there are daily soft contacts, which may also be disposable. Soft contacts are made of flexible plastic that is permeable to air and more comfortable than hard ones. Similar to the name, daily wear soft contacts must be cleaned on a daily basis only with a particular solution recommended for that purpose. As stated, they also come as disposables that are thrown away at the end of one day. And therefore, the need to purchase and use a cleaning solution will never be necessary in this case. Second, there are planned replacement soft contacts which are replaced according to a schedule at planned intervals.
Specifically, the most significant advantage of continuous wear contact lenses being permeable is that more oxygen is therefore able to get through to the wearer's cornea and assist in the fight against infection. In fact, this type of contact was not completely safe enough for widespread use when first approved and introduced, in the United States, by the FDA in 1981. According to experts, two of the key factors that contributed to the evolution of these contacts to a more wearer friendly status: the introduction of disposable contacts and the fact that wearers often practice what is known as 'flexible wear.'And 'flexible wear' means utilizing continuous wear contact lenses by normally taking them out at night, and only leaving them in now and then during a nap or while camping out in the countryside - with the comfort of knowing that there is minimal, if any, risk involved in doing so. Moreover, a person can choose to opt out of the full time period officially allowed for wear and get a new pair whenever they themselves feel the time is right. Please note that although one can decide for themselves when to shift to new contacts: if a vision professional directs a person to discard them, then it is vital that the advice is followed, and at once.
Of course, as with just about any product, there are some drawbacks to using continuous wear contact lenses. To illustrate, there is still the risk of dangerous organisms, such as bacteria and fungi, entering the eye and getting stuck underneath the contacts. Further, such organisms are in their growth element underneath the lenses where it is moist and warm. Subsequently, lens-related infections such as pink eye can result. Moreover, if left unchecked, eye infections can eventually lead to blindness. Another obvious drawback is that people who remove the contacts every day risk a decidedly lower level of complications. Naturally, the best way to avoid complications is to always follow the eye care professional's instructions regarding the contacts. And too, a person should realize that wearing their continuous wear contact lenses while swimming, for instance, raises the risk of infection. Furthermore, those who are prone to eye infections will also run a heightened risk with the use of extended contacts. And the same goes for those who are either habitual smokers or often in an environment where there is smoke of any kind. But the best way to gauge how things are going: daily self-observation. In other words, those who have chosen continuous wear contact lenses must evaluate how their eyes feel, look, and the quality of their vision ability. For example, an irritated feeling or unusual redness or not being able to see as well as usual are all excellent reasons to remove the contacts and make an eye doctors appointment.
In conclusion, for those who are able to tolerate them, continuous wear contact lenses are a great relief and aid in the course of daily living. Just as long as one stays in touch with what the doctor has recommended and monitors the efficacy and continued comfort, these contacts can greatly enhance the experience of waking up to a joyous sight.
