Human eyes absolutely need oxygen in the same way the rest of the body does. Traditional contact lenses were very unhealthy in this matter – they let very little air reach the cornea, which in turn led to eye swelling, irritation or even more dramatic effects, especially after an extended period of lens usage. A big step in the evolution of contact lenses was taken along with the invention of silicone hydrogel lenses in 1999.
This innovation increased the breathability of the contact lens by up to five times, but the silicone made the lens more hydrophobic – resistant to water. The producer of AIR OPTIX contact lenses handled this problem by implementing a unique surface treatment technology and incorporating innovatively designed materials, which made the lenses very comfortable. Users do not need to worry about eye dryness that has been traditionally associated with lens usage, as Air Optix contacts keep eyes constantly hydrated and comfortable. Furthermore, comfort does not diminish during the day as the lenses are deposit-resistant and stay clean and crisp for long hours. As a result, the clarity of vision is maintained at the same, extraordinary level, even when the lenses are being continuously used.
