LightBulb: The app that protects your eyes

LightBulb: Protect your eyes from the screen!

How many hours do you spend looking at the screen every day? Whether you're working on your computer, browsing the web, or watching videos, your eyes are constantly exposed to bright light from your screen. This light, especially blue light, can cause eye strain, headaches, and trouble sleeping. The solution? LightBulb - a smart app that automatically protects your eyes!

🔍 What is LightBulb?

LightBulb is a free program for Windows that works like "protective glasses" for your screen. It automatically changes the colors of your screen depending on the time of day:

            Morning & Afternoon: Bright, vibrant colors for better work

            Evening & Night: Warmer, reddish colors that don't strain the eyes

Think of it like natural sunlight: in the morning it's cool and bright, in the evening it becomes warmer and more relaxing. LightBulb does exactly the same with your screen!
