Night Vision: The Case for Red in the evening

Moving about when it's dark without troubling sleeping individuals is an ability that can be handled utilizing red lighting. At night this was an important development because night vision would be required to see out through the periscope.

All panel indications were changed from white light to red light. In the ceiling fluorescent light components there were 2 tubes-- one white and the other covered in red. Changing to the red tubes would darken all the areas on the ship-- especially in the Control Room.

By moving to red lighting in the ship our eyes promptly started to adjust. This is called "night vision.".

In the back of each eye is a "retina" including rod and cone cells (photoreceptors) that are light delicate. These cells react to light going into through the eye's pupil. Rods react to low light levels.

The rods can allow you to see the ambient light of an overcast night without any moonlight. The cones reply to the ambient light of a night with 50 % moonlight all the method to complete sunshine.

How Night Vision Works.


In bright light the rhodopsin particles divided into 2 other particles (retinal and opsin) avoiding the rods from displaying night vision. The cones are no longer beneficial in the dim light and the rods at first do not have sufficient rhodopsin for night vision, so we are briefly night blind. In a couple of minutes, night vision comes to us and we can see in the poorly lit environment.
