When I was doing the new trial (mostly its Extreme version) I feel a some discomfort but couldn’t tell exactly why.

Then I did M5S and M6S a bunch as tank last week and felt ok, although yesterday evening I played them with friends and I was RDM. After an hour I started getting bad headaches and had to ask for extra breaks. I’m suspecting that the flashing lights of M5S and the bright colours of M6S ended up being too much for me when I also had RDM’s big attacks happening, because I didn’t feel as much discomfort if I looked away from my screen during my burst windows, and I haven’t had this problem playing RDM in other content, or when doing M5S/M6S as GNB instead.

This has never happened to me before when playing this game, and I wasn’t sick yesterday and am feeling completely fine today. I started playing this game in 5.5 and started raiding in 6.2. However there are times if I’m playing other games, or am watching tv, or am at concerts, where I can have discomfort or headaches because of bright lights.
I want to highlight this post because this is a textbook example of how the lighting in this game impacted me and other players who have brought up this issue here and in other threads. It's not like staring at the sun where the pain is immediate and you reactively look away. The effect when playing the game is subtle and sustained over a long period of time. If you play games or work with computer screens regularly, you might not even think to question it. Out of nowhere your head hurts (and keeps getting worse). You might feel sick to your stomach. You might start making mistakes for no apparent reason and play worse than you normally do.

I do have light sensitivity so when I started feeling sick when running Vanguard, I was able to identify the culprit quickly - the sirens and flashing lights are obvious. The Arcadion fights are so brightly lit already and amplified by the flashy new effects. Bright on bright on bright may not consciously click as something wrong when you're focused on trying to clear the fight, but your eyes are still processing that visual information. For some people, it's overwhelming. For the people who have spoken up here and in other threads, it's game-breaking. If you're reading this and thinking this sounds familiar, please go easy on yourselves.

But as stated in this quoted post, I'd also never reacted that badly to something in-game before. This has been an issue with previous duties but it has gotten significantly worse in DT and specifically 7.2. Players need ways to mitigate this if they want to keep playing this game, and it has to be something implemented by the devs and not mods.
