## Description

Night: Blue Light Filter is a Chrome extension designed to reduce exposure to blue light emitted by electronic devices. Blue light, with wavelengths between 380-500 nm, is known to cause eye strain, disrupt melatonin production, and negatively impact sleep cycles. Prolonged exposure can also increase the risk of age-related eye diseases such as Macular Degeneration.

This extension offers an easy and fast way to block and adjust the intensity of blue light emitted from your screen, helping to protect your retina and improve sleep quality. Additionally, it is optimized to save your device's battery life while enhancing your viewing comfort during night-time use.

Users appreciate the app's effective blue light filtering, simplicity, and developer responsiveness. However, many report major issues like unresponsiveness of phone controls during filter use, the app turning itself off unexpectedly, lack of brightness control, and non-functional schedule settings.
