Abstract

An anti-dazzling screen comprises a body which has a first surface, a second surface opposite to the first surface as well as a through hole penetrating through the body. The anti-dazzling screen is characterized in that an identification layer in the color different from that of the first surface is arranged on the first surface; alternatively, an identification layer in the color different from that of the second surface is arranged on the second surface.

Description

technical field [0001] The present application relates to an optical element, in particular to a light-shielding sheet and an image lens with the light-shielding sheet. Background technique [0002] In recent years, portable electronic products have developed rapidly, such as mobile phones, tablet computers, etc., which have flooded the lives of modern people, and imaging devices mounted on portable electronic products have also flourished. With the development of science and technology, users have higher and higher requirements on the quality of imaging equipment on portable electronic products. Therefore, in addition to continuously improving the quality of optical design, imaging devices on portable electronic products also need to improve the structure of the light shield, increase the correctness of assembly, and improve the imaging quality of the imaging lens. [0003] Usually, a shading sheet is arranged between lenses of an imaging device on a portable electronic pr...
