Focus Night & Day contact lenses are almost breath-taking in their elegant design and in the effectiveness of their help. The creators of these contact lenses have meticulously studied the various factors which are required in order to make an effective contact lens, and applied them religiously.
Oxygen is simply critical for good eye care and health, because without it, the risk of infection and irritation of the eye increases at an exponential rate and so in order to better facilitate the passage of oxygen, these lenses are made with silicone hydrogel with the presence of the silicone allowing up to six times the volume of oxygen to be absorbed into the eye.
A common complaint about monthly disposable contact lenses is that they can only ever be worn for a maximum period of twelve hours each day before they need to be swapped around and this can be a rather irritating and cumbersome process.
What makes the Focus Night & Day lenses so beneficial for the contact lenses wearer then, is their ability to be worn 24 hours a day for a full month! Such lengthy durations of time are practically unheard of with your average disposable lenses.
However, please note that if you do keep your lenses in for that length of time without any attempt to clean them, you will run a substantial risk of acquiring an infection, because of the build up of protein fibers behind the lenses themselves.
However, it should be noted that all of the research thus far have indicated that contact lenses which are created using silicone hydrogel are safer. Standard lenses which use only hydrogel and which are used for 24 hours a day run present five times the level of risk of cornea inflammation.
