Claim 17:
18. A method of making an ophthalmic device, the method comprising:
(a) providing a monomeric mixture comprising:
(i) greater than 50 wt. %, based on the total weight of the monomeric mixture, of one or more non-silicone-containing hydrophilic monomers;
(ii) one or more crosslinking agents; and
(iii) one or more red-light blocking compounds blocking greater than about 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nanometers (nm) to about 800 nm, wherein the one or more red-light blocking compounds have one or more ethylenically unsaturated reactive end groups;

(b) subjecting the monomeric mixture to polymerizing conditions to provide a polymerized ophthalmic device, and
(c) hydrating the polymerized ophthalmic device.
