20100321633 | PROGRESSIVE OPHTHALMIC LENS - The invention provides a progressive ophthalmic lens suitable to be worn by a person engaged in a sporting activity. For this purpose the lens has a far vision region which is enlarged, and a peripheral field of vision which is separated and whose mean sphere gradients are gentle. When a progressive lens of this kind is allocated to a wearer, the lens can have an addition value that is approximately equal to a prescribed value, or an addition value that is less than the prescribed value. | 12-23-2010 |
20110317128 | SPECTACLE EYEGLASS FOR MYOPIC CHILD - A spectacle eyeglass of progressive addition type has been designed for myopic children. To this purpose, an ergorama has been constructed, taking into account vision conditions encountered by the children in their everyday life. In particular, the eyeglass has a limited optical power increase between two reference eye directions (D | 12-29-2011 |
