Glare is the most common and easily underestimated source of burden for screen users: the screen surface turns the lamps and Windows into a "second light source", and the eyes repeatedly adapt between the brightness of the content and the reflected brightness. The governance path has a clear priority: first adjust the environment (the position and Angle of the light source), then modify the components (reduce the surface reflectivity), and finally brighten the screen for hedging.
The AR anti-reflective coating reduces the reflectivity from 4% of ordinary glass to the 0.5% level, and the dark reflection base color is reduced by approximately 88% - this is a relatively effective single-point improvement at the device level.
A quick overview of key terms
AR anti-reflective coating
AR (Anti-Reflection) anti-reflection coating is an optical film that reduces surface reflectivity by using destructive interference. It is commonly found in glasses, camera lenses and high-end screen protectors. ... This page focuses on: Reflection and Glare Special Topic: From Principle to Control
Reflectance
Reflectance is the ratio of the intensity of reflected light on a surface to the intensity of incident light. The typical value of a screen glass surface is about 4%, and it is a core indicator for measuring the "degree of reflection". ...

Contrast
Contrast is the ratio of the brightness of the brightest to the darkest areas in an image, which determines the depth and layering of the black areas. Environmental reflection is the main external factor that depresses the "effective contrast". ... This page focuses on: Reflection and Glare Special Topic: From Principle to Control
Glare
Glare refers to the discomfort or reduced visibility caused by bright areas within the field of vision where the brightness is much higher than the environmental adaptation level (such as light shadows or window shadows). Screen mirror reflection is a common source. ... This page focuses on: Reflection and Glare Special Topic: From Principle to Control
