Abstract
A gas permeable ophthalmic lens material comprises a tetraethoxysilane and an ionic silane. The ionic silane comprises positive charges and negative charges. The lens made therefrom thus comprises positive and negative charges, thus the gas permeable ophthalmic lens is hydrophilic, and prevents adhesion of bacteria in allowing the surface of the human eye to breath. A gas permeable ophthalmic lens made of the gas permeable ophthalmic lens material is also provided.
