Abstract
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, D), a start (D) of the optical power increase which is located quite low in the eyeglass, and an offset value (OS) for a meridian line (ML) which is higher than that of eyeglasses designed for adults.
