Extended wear contact lenses certainly have some benefits. If you wish to wake up in the morning with perfect vision and hate having to clean and disinfect your lenses, they could be absolutely ideal for you.
Contact lenses are usually prescribed in two schedules. Firstly, there are daily wear varieties which users remove before sleeping. These can be daily disposables but, if they are not, then these contact lenses require regular cleaning and disinfecting before they are safe to use.
However, extended wear lenses are designed to be worn overnight. This means that the cleaning process is avoided, adding to the convenience of lens wearing. This kind of lens is more porous than normal lenses, which ensures that oxygen circulates behind the lenses and reaches the cornea. Extended wear lenses are specifically engineered to assist this circulation, which helps to maintain eye health.
If you are thinking of switching to extended wear lenses, it is vital that you consult your optician before ordering. This is because some conditions prevent patients from wearing extended wear lenses. If you do qualify, these lenses can be worn for up-to a month without removal, and are far more convenient that conventional lenses.
There are newer models of extended wear lenses coming onto the market as well. These can be made out of advanced materials like silicone hydrogel. This allows enough oxygen through to your eyes even while your eyelids are shut during sleep.
All of the extended wear lens varieties sold by Vision Direct are produced by world-leading vision specialists and include varieties like Air Optix Night & Day , Acuvue Oasys, Biofinity and Purevision.
These kinds of lenses are known to be particularly gentle on sensitive eyes, which allows them to be worn continuously for periods up to one month. They can also be purchased in forms that are designed to deal with conditions like presbyopia or astigmatism and can be found in multifocal forms as well.
How long you can keep you extended wear contact lenses in for varies depending upon the individual. For some, keeping your lenses in for a whole month might be a little uncomfortable. That’s why you should think of 30 days as the longest permissible time, and check to see what works for you. Your optician will also be able to advise on what would be best for your eyes.
Whatever type of lens you wear, excellent hygiene is vital in warding off infections and ensuring that eyes remain healthy. With extended lenses, this simply means not wearing them past the recommended usage date. It is also not advisable to wear these lenses while taking a swim or bathing in a smokey or steamy environment.
If your eyes do become irritated or sore while wearing extended wear contact lenses, and whenever your vision is impaired, try a fresh pair of lenses. If your vision doesn’t improved, the lenses should be discarded and you may need to consult your optician to devise an alternative lens wearing strategy.
