Monofocal ophthalmic lens with index gradient and without geometrical power

摘要

This is a lens having spherical concave and convex surfaces and a variation of index. …??According to the invention, its refractive power (PO) being due only to its variation of refractive index, its geometrical power (PG) is zero, however the aberrations are held within suitable limits. …??Application to correcting ophthalmic lenses. …IMAGE…
