Contact lenses can significantly affect lifestyle choices of those with weak vision. This area of eye-wear has seen technological improvement in terms of materials used and designs of contact lenses, allowing greater flexibility to all the users.
You can choose between daily wear contact lenses and extended wear contact lenses. The difference between these two is that the daily wear contact lenses are designed to be removed each day for cleaning and are to be removed before you sleep or nap, and the extended wear contact lenses can be worn continuously for up to 7 days before they need to be removed for cleaning. The daily wear contact lens should not be worn for extended time as misuse can lead to temporary or permanent damage to the cornea.
The latest favourite is extended wear contact lenses. These are contact lenses that can be worn continuously for six nights and seven days, some even for a month. You can keep these lenses on even while you sleep.
Are Extended Wear Contact lenses Good For Me
If you wear contact lenses regularly or for a long time every day, extended wear contacts will be a good option to consider. The modern day extended wear contact lenses are made with silicone hydrogel lens which allow more oxygen to pass through the lenses to the eyes. It decreases the risk of hypoxia which is responsible for making the cornea more susceptible to inflammation and infection.
Moreover, almost all the extended wear contact lenses are disposable that can be discarded after 2 weeks or a month. This prevents build-up of proteins and other lens deposits that cause eye inflammation and discomfort and create a hospitable environment for the growth of infection-causing microorganisms. All these factors suggest that wearing extended contact lenses is definitely a good idea.
