Extended wear contact lenses is one of the high end development and improvement in the field of lens wear.
In the past, the normal way of wearing contact lenses is that the user will have to wear the lens for a day but it has to be removed before going to sleep. There are also some hear says that contacts should not be worn more than 8 hours a day.
But all these have come to pass due to the birth of extended wear contacts. When we say extended wear, this means that the users can wear the contacts for as long as they want even if it is during sleep or not.
The main purpose of developing extended wear contacts is to give sight to people at all times even in the absence of eye glasses. Even for those with presbyopia, multifocal extended wear contact lenses are also available.
The problem with people with poor vision is that whenever they wake up during mornings, the surrounding is blurred. Hence, they are dreaming of waking up one morning without having to reach first for the lens holder and insert it in their eyes.
There are also instances wherein one has to grope during nights and whenever it is dark all the way to the washroom because of poor eye sight. Without an eye glass or a contacts inserted in their eyes, everything is so difficult and causing more problems. The movements are limited and hence, only a few things can be accomplished.
Extended contact lenses are safe to wear for a long period of time or during sleep because its oxygen content is 6 times loaded as compared to regular contact lenses. This has been made possible with the usage of the soc-called “highly permeable hydrophilic polymeric materials”.
These materials will allow the users to wear the contacts for a period of 7 days to 30 days of usage on a continuous manner. This timeframe is computed on the basis that no cleaning, removing and disinfecting will be made. This only means that even if the users or the wearers of the contacts will wear it for a 30-day period, straight and without removing the contacts from the eyes, it will surely not be detrimental to the health of the users.
The reason behind this lens’ capability is that the lenses are allowing a great amount of oxygen to go through the eye’s cornea. Hence, even if the lenses will be used for about 30 days straight, the eyes will not feel or experience any sort of irritation and dryness as well. In addition to this, extended lenses have biocompatible surface that is special in nature which reduces not just the protein build-up but more so the accumulation of bacteria.
However, if you want to feel even safer, you should try to remove the lens once in a while and cleanse it so that it will give you more confidence that you will not experience any complication. Anyway, too much of everything is bad at times. Cleanse your lenses whenever you feel it.
