Hello fellow eye-strain sufferers,
I am a photographer and as many of you here I suffer from eye-strain induced by modern displays, which makes my job really difficult. I go to art exhibitons quite often and I have noticed something completely unrelated to displays, that causes very similar if not the same problem in me.
Below are attached photos of large scale paintings and digital art, that caused me very similar symptoms few seconds after trying to look at them.

The first is a painting of 1025 different colors, often differing in only very small gradients, but none is the same. It is large scale and when standing close, unescapable. The amount of colors seemed uncomprehensible to me and I could not fix my eyesight on any given part of it, causing me eye-strain like from LED displays.
The paintings followed with other examples of color-sensory overload:

This one was expecially painful, however locking my eyes onto a spot where light was reflected, I experienced somewhat of a relief (meaning matte displays probably do the same comparede to glossy ones).

What is funny is, the artist realizes it himself, stating:

What I find really interesting about this is, that it is completely unrelated to LED displays or light. The eyes simply cannot rest, drifting from one color to the other, until they get really tired really soon and head-ache and migraines follow.
I think this is an interesting experiment, because it separated things like PWM etc. and is a sole example of what a color-overload can do to you. Funnily enough, my friend did experience the same problem, however is unaffected by displays.
My theory is maybe some people here are really sensitive to too many colors in one place, and this might constitute one of the pillars of the problem we all have.
I am very interested to hear what you think about this.
