NightVision Light: Keep Your Night Vision Intact
NightVision Light is an Android app developed by 株式会社 ビクセン that turns your smartphone screen into a red-lit flashlight, perfect for astronomical observation at night. This app is designed to help you maintain your night vision while using a telescope or operating other equipment in low-light environments.
When observing celestial objects with a telescope at night, it is essential to adapt your eyes to the dark environment to perceive faint objects. However, there are times when you need additional light to check a celestial map or illuminate your surroundings. Using a white flashlight can contract your pupils and disrupt your night vision.
NightVision Light solves this problem by providing a red-lit flashlight on your smartphone screen. The intensity of the red light can be adjusted to your preference by swiping up or down on the screen. This allows you to maintain your night vision while still having the necessary illumination. The brightness setting is even saved for your convenience in future uses.
Overall, NightVision Light is a useful tool for astronomers and anyone who needs to preserve their night vision in low-light situations. With its simple yet effective functionality, this app is a valuable addition to your smartphone's utility toolbox.
