My eyes hurt after i spend more than 2 hours on 'Boards'!

Hi, not to be mean, i really like Boards, but i find it little too dark. If i spend some time here on Boards, i notice some disruption and tiredness in my eyes, specialy when going back to white pages like Youtube, Facebook and such.

Maybe lighten up a little the colours, i don't know what i can suggest but right now it's quite irritating.

Thanks.

Edit: 2 hours was sarcasm btw, it needs only like ~20min for that to happen, sadly.
