Do your eyes feel tired when you look at your mobile phone at night? Do you have trouble falling asleep after looking at your phone for a long time? Blue Light Filter is here to help. Developed by Sun25, this free Android app aims to reduce eye strain caused by blue light emitted from mobile phone and tablet screens.

Scientific research has shown that blue light, with a wavelength range of 380-550nm, can disrupt circadian rhythm regulation and potentially lead to eye diseases such as age-related macular degeneration (AMD). Additionally, exposure to blue light suppresses the secretion of melatonin, a hormone that affects sleep-wake cycles. By reducing the amount of blue light emitted from your phone screen, Blue Light Filter can effectively alleviate eye fatigue and improve sleep quality.

With Blue Light Filter, you can easily adjust the light on your phone screen to a warmer and softer tone, mimicking the natural light at sunset. By switching your phone to night mode, you can significantly reduce the amount of blue light reaching your eyes, providing a more comfortable viewing experience at night. Say goodbye to tired eyes and restless nights, and start enjoying the benefits of reduced blue light with Blue Light Filter.
