Silicone Hydrogel Contact Lenses

Silicone Hydrogel Contact Lenses are designed for the continuous wearer market and for those wearers needing more oxygen transmitted to their eye. Contact lenses were traditionally manufactured using hydrogel polymers. The water in the lens was the method by which oxygen was transmitted to the eye. More oxygen enables the user to wear the contact lens for longer. However as time progresses, the water slowly evaporates and the lens dries out. Silicone Hydrogel technology has since revolutionised the contact lens industry. As silicone is oxygen permeable, the material itself allows oxygen through to the eye without having to depend on water content. Lenses are less prone to dehydration which means the lens can be worn for longer.

Silicone Hydrogel contact lenses can transmit up to seven times more oxygen than conventional soft contact lenses. By allowing more oxygen to the eye, the silicone hydrogel contact lenses will be deemed a healthier alternative by your optician. It is in fact this oxygen permeable material that is most likely to grow the next generation of contact lens wearers with prescriptions available for astigmatism, presbyopia, farsightedness or nearsightedness.
