. Night vision goggles seem green due to the physiological properties of the human eye. Our eyes have specialized photoreceptor cells known as rods and cones. Rods are extremely sensitive to low amounts of light and are clustered in the retina's periphery. They are especially receptive to wavelengths around 498 nanometers, which are similar to the color green. This innate sensitivity makes green light more visible to the human eye in low-light circumstances. The sensitivity of human eyes to various light wavelengths Green light was chosen for night vision goggles because it roughly matches the peak sensitivity of human eyesight in low-light conditions. Cones, which are responsible for color vision under stronger lighting, are the most sensitive to green light. This sensitivity enables users to distinguish details and shapes more efficiently when using night vision goggles in the dark. Furthermore, green light is less likely to produce eye strain than other colors, resulting in a more comfortable viewing experience over time. Green Phosphor Technology in Night Vision Goggles. Green phosphor technology enhances the green color of the night vision goggles. This technique turns incoming light into electrons, which are subsequently amplified and converted back into visible light. Green phosphor has great contrast and resolution, allowing users to detect objects in low-light circumstances. Green phosphor is a popular choice in night vision technology since it is compatible with human eyesight and causes less eye strain. Contrast and Visibility in Low-Light Conditions. In low-light situations, green light provides better contrast and visibility. Human eyes are less sensitive to colors like red and blue in the dark, but green light shines out due to its wavelength and our eyes' natural response to it. This color scheme improves the capacity to navigate and detect items or potential threats effectively. Furthermore, green light has minimal interference with natural night vision adaption, allowing users to maintain good vision under varied lighting settings. Show Less
