Description
The Light for Night Vision app allows you to use your smartphone as a flashlight of red color light during your session of astronomical observation.
When observing at night with a telescope, you adapt your eyes to the dark environment to perceive a faint celestial object in the field of view of your telescope’s eyepiece. As your eyes become accommodated to night vision, the pupils open widely to collect more light. You may occasionally want to check with a celestial map in the dark, or you may need to illuminate your finders and around to operate the telescope, a camera, and so on. In that situation, the illumination light of a white light flashlight will contract the pupil if it is used. As the result, you will have to wait a short while until the eyes are accommodated to the dark again.
The Light for Night Vision app helps you to keep the ability to see in reduced illumination in the dark by turning the screen on your smartphone into a red light flashlight. The intensity of the red light illumination can be varied brighter or dimmer by swiping up or down on the screen. The brightness setting adjusted is saved for next time use.

Excellent for my astronomy uses. Can check charts without ruining night vision.

Very simple but effective full screen red light. Really easy to adjust intensity.

Oh wow, no kidding, that's cool. Will see tonight if there are any ads that break up the red, but that was super simple. I thought I needed to click bright up or bright down, but you just swipe and control brightness super smoothly.

Pretty dumb description says it turns your flashlight to red light not your screen on your phone and still stupidly doesn't do anything else but that wow....lame

Overthinking ruined this app. Perfect before update, now can be unintentionally/too easily switched from red to white light. White light spoils dark adaptation, please make this feature more hidden or difficult to access (or best yet, go back to previous version without unneeded white light option). Please? Really, please?

It doesn't work, I tried it with NVGs. If it did work, it defeats the purpose. I have a 1000 lumen flashlight supposedly that can shine a mile away, is that night vision? No. It's a light.
