I have been having issues with my eyes for since 2020. Previously vision was 20:20. I have been to the Optician half a dozen times, paid for Eye Specialist who diagnosed acute allergies, spent thousands on eye drops, scratched my Cornea twice and it literally is an ongoing issue that is still pending resolution. Thing is, I have just had 3 weeks off work and my eye's had returned to as close to normal as they have been in as many months. This is my first week back at work and by day 3, the issue had returned which in retrospect identified that my eye problems align with the timing for when my employer upgraded our monitors to the U2417H Dell models. 

I have just read the white paper which stated the following: 
WARNING: The possible long-term effects of blue light emission from the monitor may cause personal injury such as digital eye strain, eye fatigue and damage to the eyes.

Is there some sort of screen protector that mitigates this? I am somewhat dumbfounded that eye care specialists, doctors and even our OHS dept has not worked out the problem is the monitor. Need urgent guidance please as the disruption to daily life not to mention related expenses is exasperating.
