Abstract

Provided are a low hydrous soft ophthalmic lens that can remarkably reduce or avoid a phenomenon in which a lens sticks to a cornea when worn and can reduce a decrease in the performance of a coating layer when rubbing the low hydrous soft ophthalmic lens for cleaning and a method for manufacturing the same. The low hydrous soft ophthalmic lens has a layer formed of a hydrophilic polymer on at least part of the surface of a base material containing a polysiloxane compound, and at least part of the inside of the layer is cross-linked.
