Technical Field

The application belongs to the technical field of lenses, and particularly relates to an anti-reflection film anti-red light lens.

Background

In a production environment, light rays that cause damage to the eye include ultraviolet, visible, and infrared. Ultraviolet rays and infrared rays are main causes for inducing cataract of human eyes, and high-intensity ultraviolet rays and infrared rays exist in strong sunlight or special production environments. In daily life, people have less chance to touch laser or artificial strong light sources, but this does not mean that ordinary people do not need daily protection for their eyes. It is known that 10% of solar radiation is ultraviolet energy, about 40% is visible light, and the remaining about 50% is all infrared light. In the past, people pay attention to protection of ultraviolet rays, but are better at preventing visible light and infrared rays (particularly near infrared short waves), ultraviolet light is low in atmospheric penetration capacity, common resin lenses have strong absorption to the ultraviolet light, and with the development of science and technology, the existing resin lenses can absorb a blue light wave band of about 410nm, so that damage to human eyes in nature is limited. In contrast, infrared light has a strong transmission capacity, and is absorbed only slightly by existing lens materials, so that a large amount of infrared light can be irradiated or reflected to the human eye. Near infrared light can reach the fundus and is mainly absorbed by the retina; the mid-far infrared light and the far infrared light are mainly absorbed by the cornea and cannot reach the fundus. Therefore, an anti-infrared lens with good protection effect and better anti-reflection capability is lacking at present.
