[0002] With the development of science and technology, people's work, life and entertainment rely more on human-computer interaction, which is efficient and convenient, but also causes harm to visual health, especially the visual health of children is more pessimistic than ever. The Ministry of Industry and Information Technology statistics report shows that the number of mobile phone users in China has exceeded 1.3 billion in January 2016. The mobile phone display screen is actually a light source, and long time staring at the display screen will cause visual fatigue, eye discomfort, and even eye disease in serious cases. With the development of VR and AR virtual reality display technology, the relationship between the human eye and the light source has entered a new era. The panel of virtual reality display often causes visual fatigue, but the existing lens only focuses on the increase of the degree and the improvement of the refractive index, and ignores the antireflection effect of the lens, that is, the functional film layer coated will affect the antireflection of the lens, resulting in weakened light transmission and increased wearing fatigue.
