I don't know about the damage to eyes, but I can confirm problem with not getting "sleepy feeling" while using a computer late at night. And the solutions for me was a software that gradually changes the color scheme of the operating system to be more red and less blue. I'm using it since almost a year and it significantly helped with going to sleep earlier. I simply get sleepy at 22-23, even when doing stuff on a computer. Before installing the software I could sit for hours and notice it's already 02:00 and I'm not sleepy, just tired.
