  • Oxygen permeability expresses the ability of the lens to let oxygen reach the eye by diffusion. It is dependent on the thickness of the lens and the material of the lens, especially concerning the water content.
  • A higher Dk value means higher level of oxygen can pass through the lens and reach the eye.


In the digital device era, where one often experiences extreme dryness resulted from lack of blinking, ULTRA contact lenses come with the MoistureSeal technology molecules, that absorb and retain moisture for a very long time. The lens contains four times the amount of PVP than other silicone hydrogels, which results in increased water retention, and features a smooth and durable lens surface with a thin edge, all of which result in greater comfort. On top of that, ULTRA lenses pride themselves for having the highest oxygen permeability compared to any other silicone hydrogel lenses in the market, making it the obvious choice for healthy white eyes. Now also available in multifocal, you can enjoy the benefit of ULTRA contact lenses at any age!
