What are the functions of red coated lenses?
The core function of red coated lenses is to filter blue light, violet light and some stray light, while enhancing the transmittance of red and yellow light to meet the needs of specific scenarios.

The specific functions and applicable scenarios are as follows:
1, Improve visual clarity in specific environments
After filtering blue and violet light from the sky, glare and foggy vision can be reduced. In outdoor sports such as shooting, hunting and golf, the outline of targets and distant scenery can be distinguished more clearly.
2, Relieve eye fatigue (in specific scenarios)
Some red coated lenses can block harmful blue light emitted by electronic screens, making them suitable for people who face displays for a long time and reducing eye soreness.
3, Enhance color contrast
Improve the recognition of red and yellow light. In low-visibility environments such as snow and fog, color changes can be captured more sensitively and environmental recognition can be improved.

It should be noted that red coated lenses will change the original color of the scene. Wearing them during daily commutes may affect the judgment of colors such as traffic lights, so they are not recommended as all-purpose lenses for all-weather use.
