New Android App Makes it Easier to Use Your Phone While Stargazing

The red filter on the Sunset app doesn't ruin your night vision.

Ever have to take a call while stargazing, or do you use astronomical apps on your phone, only to have the white screen ruin your night vision? A new app called Sunset is a screen filter that essentially adds a dimmed red-color filter onto an Android device’s screen so you can use your smartphone during those extra dark moments and not lose your dark-adapted night-vision.

The app’s description says it best:

Sunset is a screen filter adds an additional layer of dimming color to help soothe your eyes during those extra dark hours. Perfect for astronomers/stargazers looking to preserve their night vision, late night smartphone users, and movie theater texters. Sunset goes darker than Android’s brightness settings to provide your eyes with that extra layer of comfort.

Sunset is easy to use, too. Just select a color theme, choose the maximum intensity, and hit start. The color themes are specifically designed to help your eyes in different environments, as there are several other color options.
