This of course is a very incomplete answer but so are the answers red or <a href="https://stlplaces.com/blog/how-to-enable-and-use-blue-light-filters-for-eye">blue-green</a> and you should know why.</span></p><p><br/></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">Lets start with red, specifically what I will call the red light myth.</span></p><p><br/></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">I believe the myth started in the photographic darkroom.</span></p><p><br/></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">Until about 1906 most photosensitive material (plate, film, and paper) was not very sensitive to red. Some of these orthochromatic materials are still used. This allowed these materials to be dealt with for a short time under a relative bright red light because the human eye can see red if the level is bright enough. The fact that L.E.D.s (having a number of advantages over other light sources) were economically only available in red for some time has also help to perpetuate this myth.</span></p><p><br/></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">As more research about the eye was done it was found that the structure responsible for very low light vision, the rods, were also not very sensitive to red.</span></p><p><br/></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">It was assumed then that like film you could use red light, which is seen by the red sensitive cones (there are also blue and green sensitive cones to give color vision), without affecting the rods.</span></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">It takes a while for true night vision to be recovered. About 10 minutes for 10%, 30-45 minutes for 80%, the rest may take hours, days, or a week. The issue is the chemical in the eye, rhodopsin - commonly called visual purple, is broken down quickly by light. The main issue then is intensity; color is only an issue because the rods (responsible for night vision) are most sensitive at a particular color. That color is a blue-green (507nm) similar to traffic light green (which is this color for a entirely different reason). It would seem that using the lowest brightness (using this color) additional light needed for a task is the best bet to retain this dark adaptation because it allows rods to function at their best.</span></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);">Unfortunately there are a number of drawbacks using only night vision.</span></p><script async="" src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

This allowed these materials to be dealt with for a short time under a relative bright red light because the human eye can see red if the level is bright enough.

The issue is the chemical in the eye, rhodopsin - commonly called visual purple, is broken down quickly by light. The main issue then is intensity; color is only an issue because the rods (responsible for night vision) are most sensitive at a particular color. That color is a blue-green (507nm) similar to traffic light green (which is this color for a entirely different reason). It would seem that using the lowest brightness (using this color) additional light needed for a task is the best bet to retain this dark adaptation because it allows rods to function at their best.\u003C\u002Fspan\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EUnfortunately there are a number of drawbacks using only night vision.\u003C\u002Fspan\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cbr\u002F\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cstrong\u003EAmong these are:\u003C\u002Fstrong\u003E\u003C\u002Fp\u003E\u003Col\u003E\u003Cli\u003E\u003Cspan class=\"ql-ui\"\u003E\u003C\u002Fspan\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EThe inability to distinguish colors.\u003C\u002Fspan\u003E\u003C\u002Fli\u003E\u003Cli\u003E\u003Cspan class=\"ql-ui\"\u003E\u003C\u002Fspan\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003ENo detail can be seen (about the same as 20\u002F200 vision in daylight).\u003C\u002Fspan\u003E\u003C\u002Fli\u003E\u003Cli\u003E\u003Cspan class=\"ql-ui\"\u003E\u003C\u002Fspan\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EThat nothing can be seen directly in front of the eyes (no rods in the center of the retina), you must learn to look about 15-20° off center.\u003C\u002Fspan\u003E\u003C\u002Fli\u003E\u003Cli\u003E\u003Cspan class=\"ql-ui\"\u003E\u003C\u002Fspan\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EOnly motion can be detected well, therefore you may have to learn to move your eyes to detect something that doesn&#39;t move.\u003C\u002Fspan\u003E\u003C\u002Fli\u003E\u003Cli\u003E\u003Cspan class=\"ql-ui\"\u003E\u003C\u002Fspan\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EObjects that aren&#39;t moving appear to move (autokinesis). This has probably led to a number of plane crashes.\u003C\u002Fspan\u003E\u003C\u002Fli\u003E\u003C\u002Fol\u003E\u003Cp\u003E\u003Cbr\u002F\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EIf you need to see directly in front of you or see detail you need red. Like many myths the red light myth has some basis in fact. The red truth?\u003C\u002Fspan\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cbr\u002F\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EWhy red? The center 1.5% of your retina (the fovea) which provides you with most detailed vision is packed almost exclusively with red sensitive cones.\u003C\u002Fspan\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cbr\u002F\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EThis is the same area that has no rods and is responsible for the night blind spot. There are fewer total green sensitive cones than red. The number of blue sensitive cones is very small compared to green and red.\u003C\u002Fspan\u003E\u003C\u002Fp\u003E\u003Cp\u003E\u003Cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);\"\u003EWhich is just as well since the lens in the human eye cannot focus red and blue at the same time. And using green really only changes perceived brightness because of the way the signals are processed in our neural pathways.

or military operations. To prevent disturbing your night vision, follow these guidelines:Choose a red or blue light headlamp: These colors are dimmer and have less impact on night vision compared to white light headlamps. Red or blue light won&#39;t trigger the same response in your eyes as white light does, allowing you to see better in the dark.","how-to-use-a-headlamp-while-preserving-night-vision",117205,"How to Activate Red Light Mode on A Headlamp?","blog\u002F24d42322-4e97-4e97-aba0-63365ef4d28c\u002F65c7a5554d5683bc6bcd68c1.png","To activate the red light mode on a headlamp, you need to follow a few simple steps. First, locate the power switch or button on your headlamp. This switch is typically located on the side or top of the lamp.Once you have identified the power switch, turn on the headlamp by pressing or sliding the switch into the &#34;On&#34; position. Depending on the model, you may need to press and hold the switch for a few seconds.","how-to-activate-red-light-mode-on-a-headlamp",107783,"How to Enable And Use HDR on A Gaming Monitor?","blog\u002F95aee549-316e-4adb-8e18-e02c52d8192d\u002F656dcd8c5cd93fee1cdde9bb.png","To enable and use HDR (High Dynamic Range) on a gaming monitor, follow these steps:Check monitor compatibility: Verify if your gaming monitor supports HDR.
