Method for minimising the maximum thickness of monofocal ophthalmic lenses and ophthalmic lens with refractive index gradient obtained by application of this method

摘要

This is a lens having spherical concave and convex surfaces and a variation of index. …??According to the invention, the law of variation of the refractive index is such that, in absolute value, the refractive power (PO) of the lens is significantly greater than its geometrical power (PG), however the aberrations are held within suitable limits. …??Application to correcting ophthalmic lenses. …IMAGE…
