Abstract

An oxygen permeable contact lens is provided. The oxygen permeable contact lens has a convex arcuate outer lens surface and a concave arcuate inner lens surface on the reverse side of the outer lens surface. The contact lens is provided with at least one oxygen permeable hole which is drilled by a laser linearly penetrating the outer lens surface and the inner lens surface, thereby increasing the air permeability and oxygen permeability of the contact lens by means of the oxygen permeable hole. When wearing the contact lenses, the eyeballs can be supplied with oxygen through the oxygen permeable hole in time and the circulation of tears and moisture can be enhanced, alleviating eye dryness, stabbing pains, and other discomforts and thereby improving the wearing comfort of the contact lens. Thus, a reduction of infection risks for the eyes can be achieved, ensuring a wearing safety. When using eye drops or artificial tears, the moistening effect of the eyeballs can be achieved through the oxygen permeable hole, and the convenience of soothing the eyeballs is also achieved.
