Descripción
Night Vision is designed to help preserve your scotopic vision (vision under low-light conditions) by reducing the blue and green components of your monitor's output, leaving mostly red, which aids in preserving biological night vision.
Your eyes' photo-receptors consist of rods and cones which are found in the retina, and convert light into electrical signals which are sent to the brain to form an image. Cones create our color vision and are only active in high-light levels. Rods are much more sensitive in low-light conditions, but not to color. Within your rods is the chemical rhodopsin which allows night vision. When exposed to bright light, Rhodopsin bleaches and takes around 5-10 minutes to regenerate. The rhodopsin contained withing the rods is less sensitive to the color red, and this color is often used to help preserve scotopic vision.
Night Vision operates by reducing the gamma values of your computer's three video output channels (R,G,B), particularly the blue and green channels, which allows your monitor to appear dimmer, leaving mostly red. Because it works at a hardware level across your entire screen, the benefits are not limited to only a single application. The effect can be switched on and off at any time, and adjusted to suit the ambient lighting conditions.
Astrophotographers, and video astronomers often resort to placing red cellophane over their computer monitor in an effort to achieve similar results. The Night Vision application performs this function much more easily, and with more adjustability.

Crashes on launch (MacOS Monterey)
"An exception of class NilObjectException was not handled. The application must shut down."
It worked briefly, the red effect was nice. If the author isn't interested in updating the app, they should issue refunds and list the last actual known working OS.
I think it works
I was hesitant to buy this because of the negative reviews, but there were so few overall I thought they might be skewed too heavy in one direction.
Here's what I found:
1. After installing the app, I couldn't find the menu bar icon. I think that this is because my computer is in dark mode and the icon is white. It was too hard to see against the light gray background.
2. Another reviewer here said that the application immediately crashes with some null pointer exception. I found that this is true if the option to play a sound is turned off when the view mode is toggled. Completely uninstalling the app and all preferences (especially the one regarding the sound preference) and then reinstalling and leaving the sound option alone seems to keep it alive.
Otherwise I think this thing does exactly what I want it to do and I'm really pleased to find it. I think that with a few design tweaks and a couple of well-placed null checks that this app would spread like wildfire across the couple thousand people that would use something like this. Many thanks to the developer!
Thanks red light homie
I got this app for my older Mac and I enjoy having the white lit display in my (2009 Macbook pro) not murder my eyes.
Thanks for the simple app design and integration.
