Abstract
A lens module includes a lens group and at least one coating film. The lens group includes a plurality of lenses arranged successively from an object side of the lens module to an image side of the lens module. Each lens has two effective surfaces. One effective surface is located on the object side of the lens module, and the other is located on the image side. The coating film formed on at least one of the effective surfaces. The coating film satisfies a first relationship: B<0.5%; B<0.35%. Brefers to a maximum value of a reflectivity of incident light incident on the effective surfaces. Brefers to an average value of the reflectivity of the incident light incident on the effective surfaces, a wavelength of the incident light being in a range of 490 nm to 620 nm.
