Blue Light Filter - Night Mode 1.5.8

Eyes feel tired during night reading on the phone? Have trouble sleeping after long periods of watching a phone screen?

This fatigue and sleep disturbance are caused by blue light. Blue light emitted from phone and tablet screens falls within the visible light spectrum (380-550nm) that affects circadian rhythms. Scientific studies have shown that exposure to blue light can harm retinal neurons and suppress the secretion of melatonin, a hormone that regulates circadian rhythms. It has been proven that reducing blue light can significantly improve sleep quality.

A blue light filter can help reduce blue light by adjusting the screen to a more natural color. By activating night mode on your screen, you can alleviate eye strain and improve comfort during nighttime reading. Additionally, the blue light filter provides eye protection and promotes better sleep.

Features:

• Reduce blue light
• Adjustable filter intensity
• Power-saving
• User-friendly
• Built-in screen dimmer
• Eye protection from screen light
