Description

Technical Field

[0001] The invention relates to the technical field of resin lenses, in particular to a spherical anti-blue light resin lens and a preparation process thereof. Background Art

[0002] Among visible light, blue-violet light belongs to short-wave. Due to the strong scattering of short-wave and the focus of blue light caused by dispersion in front of the retina, it will interfere with vision and cause blurred vision. High-energy blue light can damage the photoreceptor cells of the retina and cause macular degeneration, thus affecting vision. Due to the widespread and long-term use of LED light sources and computers, symptoms of eye fatigue and decreased sleep quality occur frequently, which is widely attributed to the influence of blue light emitted by the screen. Anti-blue light glasses can effectively alleviate the adverse effects caused by blue light. Existing anti-blue light glasses include reflective and absorptive types, which are achieved by coating or dyeing processes, but during use, It still has the following defects: First, the existing anti-blue light resin lenses use a hydrophilic layer or a hydrophobic layer to achieve an anti-fog effect. The hydrophobic layer of the existing lenses achieves anti-fog by gathering water vapor on the mirror surface into water droplets and falling off. However, since the sliding trajectory of the water droplets is distributed on the entire lens, it will interfere with the field of vision when sliding; second, the existing coating method is to cover layer by layer, which will cause interference between some functional films and affect their effectiveness; third, the anti-blue light function of the existing lenses is to absorb and shield the blue light, and the blue light energy is not utilized. In addition, the absorption and shielding will cause the eyes to lack blue light exposure for a long time, thereby causing eye diseases. Summary of the invention
