LightBulb

Looking for a way to ease the strain on your eyes during those long hours in front of your PC? LightBulb might just be the solution you need. Developed by indie programmer Alexey Golub, this free, open source tool helps dynamically adjust the gamma levels of your monitor based on the time of day shifting colors seamlessly from morning to afternoon, and into the night.

If you’ve ever used tools like F.lux or CareUEyes, you’ll find LightBulb works on a similar principle: it reduces blue light exposure by warming up your screen’s color temperature as the day goes on. The result? A softer, orange toned display that’s easier on the eyes, especially after sunset. Plus, it’s super simple to set up no tech expertise required. The interface is clean, intuitive, and lets you customize settings without any hassle.

Whether you’re working late, gaming, or just browsing, LightBulb helps create a more comfortable viewing experience, adapting in real time to support your natural sleep cycle and reduce digital eye fatigue. Give it a try your eyes will thank you!
