SILICONE HYDROGEL CONTACT LENS

SILICONE HYDROGEL is an advanced material contact lens that allows 5 times more oxygen ( O2 )to pass through contacts lens. It stays more hydrated, keeping the eyes moist. These lenses are made up of plastics that are hard when dry out but readily absorb water & become soft & gel like when hydrated. It contains, silicon, carbon, oxygen & other chemicals or elements. The flexible property of silicone makes it ideal and differs from all contact lenses.

SILICONE HYDROGEL LENSES sometimes mistakenly referred to as SILICON HYDROGEL. SILICON is a common mineral found in substances like dust, sand while SILICONE is a component used in contact lens so, both are different not same.

BENEFITS OF SILICONE HYDROGEL CONTACT LENS

As we know that if the amount of O2 level reaching in cornea is low, that state referred to as HYPOXIA, responsible to cause uncomfortable conditions / wearer like red eye, swollen cornea, blurred vision or eye infection.

So, here this design of SILICONE HYDROGEL LENS combats these problems for comfort of wear for short & long period.

WORK OF  SILICONE HYDROGEN CONTACT LENS

It works with unique characteristics of AQUA FORM TECHNOLOGY,

  • There is a long SILICONE chains, hydrogen bonds form to lock H2O molecules within the lens, for god wet ability & comfortable wearing.
  • It utilizes a unique SILICONE macrometer that provides high DK value that is oxygen permeability which helps eye to clear, white and healthier.
