Abstract
A lens assembly is provided. The lens assembly includes a lens barrel; a plurality of lenses arranged in an optical axis direction and disposed in the lens barrel; and a first spacer disposed between a (N)th lens and a (N+1)th lens, which are adjacent among the plurality of lenses, wherein the (N)th lens may be formed of a first plastic material, and the first spacer may be formed of a same material as the first plastic material, or may be formed of a second plastic material which has a higher coefficient of hygroscopic expansion than a coefficient of hygroscopic expansion of the first plastic, and wherein N is a natural number of two or more.
