Background
In daily life, human eyes are subjected to glare, the glare is partially from a glare light source and partially from reflection of glare, for example, when a computer is operated, the displayed content cannot be seen clearly due to reflection of scenes outside a display on the surface of the display; and when people stand in front of the glass show window to observe the scenery in the show window, the reflection on the surface of the glass show window often prevents people from clearly observing the scenery in the show window, and the like. These are all caused by light reflection from the glass surface, and the fundamental reason for this is that ordinary glass has a high reflectance. To reduce the effect of light reflected from the glass, it is necessary to subject the glass surface to a matte (reflection reducing) treatment.
