Problems solved by technology

[0004] However, when the surface of the lens is coated with a hydrophilic solution, it is not easy to apply the hydrophilic solution to the surface of the lens due to its resistance
Moreover, even when the lens is coated, the hydrophilic coating may be easily worn and peeled off due to the low bonding force between the surface of the lens and the hydrophilic coating, and it is difficult to obtain superhydrophilicity.

Abstract

A lens according to an embodiment of the present invention comprises: a substrate; and a hydrophilic coating layer formed on the substrate and containing a polymer having a hydrophilic functional group. Accordingly, a lens having ultra-hydrophilicity and excellent abrasion resistance, and a lens assembly and a camera module including the same can be obtained.

Description

technical field [0001] The present invention relates to a lens, and more particularly to a lens having a coating formed on its surface, and a lens assembly including the same. Background technique [0002] The outermost lens among the lens assemblies included in the camera module is exposed to the external environment. In particular, when the camera module is mounted on a vehicle, optical characteristics of the camera module may be degraded due to rain, fog, light reflection, dust, etc., or a field of view thereof may not be provided sufficiently. [0003] Therefore, attempts have been made to coat the lenses of camera modules with hydrophilic coatings. When the surface of the lens of the camera module is hydrophilic-coated, problems of light scattering, frosting, condensation formation, contamination, image distortion, and the like can be solved. [0004] However, when the surface of the lens is coated with a hydrophilic solution, it is not easy to apply the hydrophilic s...
