The NightVision Light is an illumination app (variable light intensity) that is best suited for operations in the dark. You can light close at hand softly with either red color light or bulb light according to your intentions. Red color light mode protects your night vision. There might be occasions that you need to confirm with a star map or check the settings of your telescope or camera in the dark with a flashlight. However, white color light of the flashlight spoils your dark-adapted eye because the pupil of your eye shrinks by it. In this reason, it is necessary to take a preventive measure against it by using a red color light of low illumination that allows for maintaining your vision in the dark. The NightVision Light app turns the screen to illumination in red color to protect your night vision. Bulb light mode prevents the reddish foreground from "star-scape" photos caused by the red color light. It is very effective to apply the red color light for operations in the dark to avoid affecting your night vision. However, amount of light received by the sensor of your camera is good enough and the red color light may cause a reddish foreground (fogging in red) in the "star-scape" night photography. To avoid this phenomenon, the bulb light model is newly applied. The intensity of the bulb light is variable. ## Key features - Variable light intensity - Red color light mode - Bulb light mode - Preserves night vision - Prevents red foreground in photos - Suitable for stargazing ## Recent user reviews (10 of 21) All indexed reviews: https://appshunter.io/ios/app/nightvision-light/id1081761997/reviews.md ### 3/5 — Not useful as a reading light *2026-04-25, version 1.2.1* Super simple, which I appreciate. No ads or selling. However the screen dims after a short time (based on my phone settings) so it is no good as a night light for reading books. Would rather a version that could override auto dimming. ### 1/5 — Still Not A Night Light! *2025-12-07, version 1.2* Get It Right App Devs! ### 1/5 — Terrible *2025-03-18, version 1.2* Worst app I’ve ever seen in my entire life. The little that is supposed to do is completely unusable and it’s not safe because there’s no privacy ptotection ### 1/5 — Perfect EXCEPT FOR... *2024-12-30, version 1.2* This app is one of the best I've used or seen in years however, the fact that the manufacturer has for so long failed to provide basic and essential privacy information is a HUGE problem. Well, APPLE is partly at fault here for releasing this without enforcing its disclosure requirements on this, this manufacturer truly has no excuse for failing to give customers this info given the amount of time this thing has been on the market. A customer is left to then conclude the app may be a means to hack and phish 😉... ! ### 5/5 — Pleasantly Simple *2024-12-25, version 1.2* I was looking for a simple low-light emitter that was easy to adjust and preferably displayed the time. This app ticks both of those boxes. ### 5/5 — Perfect! *2024-07-02, version 1.2* Goes really dim without altering iPhone brightness. Also no fiddling with buttons etc. just up down swiping anywhere adjusts brightness which is handy when stargazing etc and preserving night vision. Simple and effective. Great app! ### 5/5 — Amazing - does 100% and not more *2024-05-28, version 1.2* This app does exactly what I need, that I use as a torchlight at night where I can quickly quickly and easily adjust the brightness by swiping up and down It also shows the date and time, which I don’t need but it is also not in the way. You can change the colour to one single other choice, which is standby small button which I’ve never accidentally so again I don’t mind that it’s there. Love simple and it does the one thing aim to do exactly right ### 5/5 — Great Red Camping Light *2023-09-20, version 1.2* Thanks for this easy, super effective red light! It’s free and super well designed. Enjoy. ### 5/5 — Simple Red Light for iPhone *2023-06-20* Thank you for the free app! Interface is smooth and intuitive. Great job! ### 5/5 — Brightness level in app only!! *2022-11-28, version 1.2* The brightness of the red light changes the screen display in app only. Other apps would change the brightness on my actual phone. The red can go soo dim. Perfect for using my phone in the middle of the night as a flashlight. This was exactly what I was looking for!!! ## Frequently asked questions about NightVision Light ### What is NightVision Light primarily used for?
