A kind of anti-blue light film structure and anti-blue light lens and application thereof

Abstract

The invention provides an anti-blue-light film structure, an anti-blue-light lens and an application thereof. The film structure is composed of six films, which are a first high-refractive-index film, a second low-refractive-index film, a third high-refractive-index film, a fourth low-refractive-index film, a fifth high-refractive-index film, and a sixth low-refractive-index film in sequence from inside to outside, wherein the low-refractive-index films are made of SiO2, and the high-refractive-index films are made of Ti3O5. After single-sided coating, the beam splitting effect of the anti-blue-light film structure can achieve 400-500nm when Tmax<92% and Tave<70% and 500-680nm when Tmin>92% and Tave>94%. Blue light transmission is reduced effectively. The anti-blue-light lens is especially suitable for virtual imaging equipment. Lesion in the macular region of a human eye is not caused. The anti-blue-light lens makes images clearer by improving the transmittance of other visible bands.

Description

technical field [0001] The invention belongs to the field of optical materials, and relates to an anti-blue light film structure and an anti-blue light lens. Background technique [0002] With the maturity of injection molding technology, the application of plastic materials in optical imaging lenses is becoming more and more common. In the application of visual optical product imaging, especially in the use of VR imaging lenses, light directly enters the human eye through the lens, and the wavelength The shorter short-wave has greater damage to the human eye due to its stronger energy, so it is necessary to filter out short-wavelength light (mainly blue light) during use. [0003] In the application of optical lens imaging, in order to increase the light transmittance, manufacturers usually coat the surface with multi-layer anti-reflection film to reduce the reflection loss of surface light and achieve clear imaging effect. Currently, multi-layer anti-reflection coatings on...

AI Technical Summary

Problems solved by technology

[0004] Although the ordinary AR film can achieve the purpose of reducing light loss, because the light will directly enter the human eye during the use of the virtual imaging device, the short-wave band where the blue light is located can directly penetrate the lens and reach the macular area of ​​the eye due to its high energy, resulting in macular degeneration

The above defects make optical lenses have health risks in the application of virtual imaging equipment
