1. A method of manufacturing coated lens comprising a lens base material and a coat layer formed on a surface of the lens base material, comprising:
supplying a coating agent to the surface of the lens base material;
spreading the coating agent supplied to the surface by rotation of the lens base material;
removing at least a part of a liquid pool of the coating agent by rotation of the lens base material, the liquid pool generated on at least one of a peripheral edge portion and a side surface portion of the lens base material after the spreading the coating agent;
removing the liquid pool remaining on at least one of the peripheral edge portion and the side surface portion of the lens base material by bringing an adsorption member into contact with at least the side surface of the lens base material rotating with a rotational speed of 10 to 100 rpm; and
curing the coating agent by light irradiation;
wherein the coat layer has a thickness of 10 to 100 μm,
wherein the adsorption member comprises a melamine resin,
wherein the coating agent is a photochromic curable composition containing a photochromic compound and a polymerizable monomer,
wherein the viscosity at 25° C. of the photochromic curable composition is 20 to 5000 mPa·s, and
wherein the adsorption member has a density of 5 to 20 kg/m3.
