Advantages: comfortable, can be worn for up to six days continuously Disadvantages: cost
My boyfriend's dad is an optician and noticed I was blinking a lot when wearing my previous contact lenses, particularly when it was late at night. I explained my contact lenses had become dry and uncomfortable especially after wearing them since 7.30am.

Moving on and one of the most iconic things about the album itself is its title: as explained on The Beatles Anthology DVD set, by Sir Paul, Ringo Starr was one of those fellows who constantly got mixed ...
These lenses have been designed to allow the continuios wear during the daytime and the night time for up to 30 days. With normal day to day contact lenses you are not suppose to keep them in during the evening time as there is not enough oxygen that would be getting transmitted to the eye.
As a result of these contact lenses which are made from Lotrafilcon A, they are up to 6 times more oxygen that can be transmitted to the eye whilst wearing theses lenses, the wearing of these lenses will vary for individual patitents but can only be warn if perscribed to by the opticians and follow their instructions correctly. every month air optix night and day lenses are designed to be replaced.
