>>108709898Blue light messes with your circadian rhythm, it's not going to cause that except indirectly by her not getting enough sleep. She needs eye drops and she needs to fucking blink more and look away from the screen now and then.
Everyone please remember the 20/20/20 rule while watching (or doing any screen activities): Every 20 minutes look away for 20 seconds at a target at least 20 feet away.
