Extended wear contact lenses are the type of contact lenses that are designed to be worn continuously – whole day and whole night. The lenses can be worn for several weeks, although this will also depend on the manufacturer, or the brand of the contact lens.
Extended wear contacts are so popular during the 1970s and 80s, but then a lot of people during this time have started complaining about eye problems relating to the daily wear of the lens. Some of the problems are infections on the cornea, or being referred as the corneal ulcers. This condition of the eye is a serious and sight-threatening complication that could happen if you frequently sleep with your contact lenses on. Medical experts are still verifying if the lenses could really lead to these eye infections. Here are the Pros and Cons of Wearing extended wear contact lenses:
Pros (Advantages of Using Extended Wear Contact Lenses)
One of the advantages of wearing extended wear contact lenses is that it allows a certain amount of oxygen to be able to reach your cornea, even if you are sleeping. Therefore, the lenses are safe to be worn overnight even when you sleep, although some eye specialists would only recommend occasional overnight use of these lenses.
The most common disadvantage of extended contacts is that continuous use could promote a buildup of micro-organisms on the lenses that could lead to some eye infections as well as other vision-related complications.
Are extended wear contacts more expensive than regular contact lenses?
While most people thought that these lenses are way too expensive than regular ones, it is surprising to know that the price difference is not that big. These lenses are slightly more expensive as compared with the usual weekly, monthly, or bi-monthly disposable contacts, and are even cheaper than daily disposable contact lenses.
