Abstract

It is an object of the present invention to provide an ophthalmic solution, which provides an enhanced comfort by suitably exhibiting an moisturizing effect to an eye and advantageously preventing an occurrence of unpleasant feelings caused by fluctuation of visual acuity. The ophthalmic solution of the present invention is provided by dissolving, in an aqueous medium, a hydroxypropylmethylcellulose, which has a molecular weight below a critical molecular weight for entanglements of an aqueous solution, which contains 3 w/w % of the hydroxypropylmethylcellulose, wherein kinematic viscosity of the ophthalmic solution at 20° C. is not higher than 2 mm2/s.
