The Contact Lenses Wearing Schedule
The contact lenses have the potential of playing different role in the wearing schedule. The thing that matters most to the optician is that the people were wearing the contact lenses are feeling comfortable, and that the contact lenses were performing as well as they supposed to do. This is why the label of the contact lenses will include the wear schedule. This wear schedules are the ones that make it possible to acknowledge when it is suitable to wear and replace the contact lenses. There are contact lenses that is specifically for daily wear. This types of contact lenses are the ones that are designed for the patient to wear the contact lenses for a day, and then remove those lenses before going to bed.
However, there is a contact lenses that are known as “extended wear”, abbreviated EW, these contact lenses are the ones that are specifically designed for the continuous overnight wear, which is most likely to be typical for up to six different consecutive nights. There are more modern materials like silicone hydrogels, which are the ones that allow the wearer to wear it even longer. This is the contact lenses that can be worn for the period that is up to thirty consecutive nights. These contact lenses that can be worn for this period are often referred to as the “continuous wear”, which has been abbreviated as CW. The contact lenses that are in the extended and continuous categories maintain that area, because they were having high oxygen permeability. When people wearing the contact lenses are awake, it is very common for their eyes to be open. This is something that also contribute to allowing the oxygen that is coming from the air to effectively dissolve into the tear.
Furthermore, the air is also passing through the lens to reach the cornea. However, when sleeping, the oxygen is supplied from a different directions. This is when the oxygen is supplied. The supplement is coming from blood vessels, which are in the back of the eyelid. There is also a lens that is effectively interfering with the oxygen, in its passage to the cornea. This is something that causes the corneal hypoxia. It is possible for this to result in many complications. These complications also include a corneal ulcer. This is the condition that has the potential of permanently decreasing the vision. This is why it is important to acknowledge how to best do the wearing schedule as the doctor has prescribed.
