Can computer or phone use cause retinal damage? i use blue light filters on both devices. i work as an infosec specialist so i need to use these devices all the time?

No.Your retinas are safe. They tend to produce Computer Vision Syndrome:Dry eyes, blurred vision, headaches, eye strain for long time at the screen.Anti glare screens are beneficial.Use the 20-20 Rule:take a 20-second break to view something 20 feet away every 20 minutes. Prior refraction problems without correction tend to worsen,be sure you’re up to date on that.Use an ergonomic chair.

The light emission from a smartphone or computer monitor is just not strong enough to cause retinal damage, and the blue filters might provide comfort and do no harm. On the other hand, laser pointers are known to cause retinal damage, so avoid them and ask presenters to use red lasers as pointers, not the green ones which are too strong.
