If you don’t feel confortable when looking at a computer screen for a long time, this article might interest you.
During the last four years I had serious vision problems related to artificial light emission.
To solve this situation, I built a screen that doesn’t emit artificial light. Instead, it filters the ambiant light coming from the front.
The screen has similar performance to a normal computer screen however it needs to be positioned in a well enlightned room. You simply have to plug the screen to an HDMI cable like an external monitor.
