Red light is often used in night lighting because it does not affect the chemicals in the "rods" of the retina, which are used for low-illumination vision.

Part of the eye responsible for night vission?
The photoreceptors commonly referred to as "Rods", which are found in the retina, are responsible for night vision. (scotopic vision) "Cones" are responsible for colored vision with brighter light conditions. (photopic vision)
Are broads in the retina receptors for color?
The rods (not broads) in the retina are for night viewing and show images in black and white and shades of gray. The cones are for color vision.
Are rods and cones alike?
cones are the part of the eye that let you see color, on mythbusters they showed rods take part in our night vision
Why night vision is in green color?
Night vision goggles are electro-optical devices that intensify existing light in order for the human eye to be able to see it. Image intensifiers capture ambient light and amplify it thousands of times by electronic means to display the battlefield to a soldier via a phosphor display, hence why it is green. Green is a good choice for two reasons. One is that the phosphors, the things that glow and make the color, are relatively easy to make green, and because the eye is more sensitive to green light than virtually any other wavelength, it means that you can make your display dimmer, using less power, and the eye will still see it. I also think that to save money, night vision only captures light intensity, not wavelength, so the display would be monochrome anyway.
What do you use the sides of your retina for?
The retina has two types of cells used in vision, rodsand cones. Cones, concentrated in the center of the retina, serve both color vision and the highest visual acuity. Rods, concentrated away from the center -- at the "sides," as you phrased it -- are responsible for night vision, for our most sensitive motion detection, and for our peripheral vision (vision of objects to the side, away from the center). Paradoxically, your night-vision is enhanced it you do not look directly at objects that are in relative darkness. If you drive at night on poorly lighted roads, for example, you can enhance your night-vision of passing cars and of the sides of the road by looking straight ahead: the rods will detect motion, objects on the periphery (the sides), and objects in relative darkness. If you were to look directly at objects in darkness, you would be stimulating the cones, in the center of the retina, and your night-vision would be less effective.
By accident i recorded my friend s wedding in night-vision or night vision mode on his camcorder. what can i do to convert the file back color?
Night vision films monochrome files, so there generally is no significant color information recorded. It is likely impossible to restore the video to full color.
What does a telescope do to improve your vision of the night sky?
It magnifies the available (ambient) light. Night-vision technology amplifies available light by as much as 40,000 times.
Which forms of electromagnetic radiation can interfere with the work of astronomers?
Light. In the form of light pollution in the night sky.
What describes the effects of infrared light in a night vision camera?
Night vision cameras convert ambient light photons into electons. Those electrons are amplified by an electrical and chemical process and converted into visible light.
Why should we use sodium lamp for light sensitive materials?
Sodium lamps only give monochromatic yellow light and so inhibit color vision at night, and cause less light pullution. You can get more details at blmall.com.
Are 'infrared light' and 'night vision' the same thing?
NO Infrared light show the heat of the body
Is night vision UV vision?
No. Night Vision equipment uses infra-red (IR) light, wavelengths of light longer (lower frequency) than visible light. Infra="below", red, or light below red light in the spectrum. UV stands for ultra (above)-violet, light that is above the violet light spectrum, so higher frequency=shorter wavelength.
If mirrors need light to work what happens if you put night vision goggles and look at a mirror?
night vision creates a light that people cant see. the mirror will still reflect the light. and because of the goggles you will see yourself in the mirror

How do night vision devices work?
Simply by intensifying the available light - from stars, ambient light, etc.
Which type of wave is used in a night vision apparatus?
infared light waves
How many unicorns does it take to change a light bulb?
None. They have night vision.
