Application and principle of high contrast color powder in high contrast lenses

High contrast lenses are professional functional lenses designed to enhance visual clarity in harsh lighting environments. It is mainly used in low light, foggy, rainy, foggy, dusk, and low contrast scenes. The core optical principle lies in the intelligent management of the incident light spectrum through the built-in high contrast color powder (functional optical dye/pigment). Due to their high energy properties, blue and purple light (approximately 400-500nm) with short wavelengths in natural light undergo severe Rayleigh scattering when passing through air filled with water droplets and dust, forming a white "visual noise" or glare, greatly reducing the contrast between the foreground and background, resulting in blurred object contours and loss of details.The molecular structure of high contrast color powders is carefully designed to selectively and efficiently absorb the interfering blue and purple light bands, acting as a precise 'optical filter'. After filtering out these harmful scattered lights, more yellow, orange, and red light (long wavelength light) carrying important details can smoothly pass through the lens. The result is that the image background received by the human eye is darker and purer, while the contour, texture, and layering of the target object are dramatically enhanced, as if adding a "dehazing" and "sharpening" effect to the world, thereby significantly improving visual safety, target detection rate, and response speed.
490nm absorbs or blocks blue light, making green greener and blue bluer;590 nm absorbs or blocks yellow light, with high contrast between red and green light, making the contrast between green and red more pronounced, with red being redder and green being greener;680 nm blocks dark red, making the color even redder.By using color powder to block yellow light and enhance the visual perception of red, green, and blue, ordinary PC and PA injection molded lenses can improve their color discrimination and achieve a color enhancement effect, making the wearer's vision clearer and more colorful.

Absorbing or blocking short wavelength blue and purple light (scattered light) reduces their entry into the eyes, lowers glare, and makes the background environment appear darker and purer. At the same time, longer wavelengths of light (yellow, orange, red) can be efficiently transmitted, and the object details carried by these lights are highlighted, thereby enhancing the contrast between foreground objects and the background.Optimize visual signals instead of simply blocking them. It improves visual performance in low light or low contrast environments such as cloudy, foggy, and dusk without significantly reducing overall brightness.

Application scenarios of high contrast glasses

Outdoor sports such as cycling, hiking, running, etc. High contrast glasses can help athletes observe road conditions, terrain, and surrounding environment more clearly, improving sports safety and experience. Adopting high contrast PC lenses, specifically designed for nighttime cycling, it can effectively enhance the recognition ability of road details.

Daily use of eyes: Some high contrast glasses are also suitable for daily use. While ensuring a high blue light blocking rate, they can maintain a bright field of view, reduce screen flicker, and enable the wearer to see text and images clearly. Wearing them for a long time is also not easy to fatigue the eyes.

Special occupations: For professions that require precise recognition of colors and details, such as pilots, painters, designers, etc., high contrast glasses can help them better complete their work tasks.
