| titleOfInvention | Hydrogel contact lens |
| abstract | The hydrogel type contact lens with high water content (10) provides better oxygen transmission and improved movement characteristics on the cornea to prevent damage to the cornea and is designed for low negative optical powers. The lens body has an ultralized molded or cast posterior surface (12) with a central sectional thickness not exceeding 0.08 mm and a small edge-to-edge diameter less than 14.4 mm. Once the lens is placed on the eye, the eyelid engages on a thickened annular edge (26) of the lens to make it make a movement of about 0.50 mm on the cornea and allow the products to be removed. metabolic waste from behind the lens. The thickened edge (26) is designed to allow the eyelid to pass over the lens smoothly and to provide the wearer of the lens with good comfort, and for this purpose, there is provided a curvature (30) of the posterior peripheral surface of the lens which conforms to the shape of the curvature of the sclera of the eye. |
