What Is Silicone Hydrogel

Seotech1217 Aug, 2021Business

Silicone hydrogel lenses are soft lenses, but silicone also is used in the production of many rigid gas permeable contacts for technology transfer to improve oxygen permeability of the lenses. All contact lenses reduce the amount of oxygen that reaches the front surface of the eye to some degree. When the cornea's oxygen supply is significantly reduced ? a condition called hypoxia ? a number of problems such as red eyes, corneal swelling, blurred vision and eye discomfort can occur. Hypoxia also can increase contact lens wearers' risk for a number of eye infections.
