Few weeks ago my wife have bought a dress with crazy texture. (See picture).
After few minutes watching her in this dress, I have a headache and feel dizzy. I think there is something in it's image's patterns overloading my parts of brain that process visual information.
Consider a situation, when clothes like this are used as camouflage for urban warfare. But they made it more advanced.
The first variant is the sneaky version, that make the observer subconsciously loose focus on target wearing this camo, and observer's opponent can easily blend to environment.
The second variant is active combat camouflage: watching it for few seconds can blurry your vision, disorientate, made vomit. Even if you use binoculars, surveillance cameras, infrared vision, all this image patterns makes you dizzy.
So, consider in 198x years, two armies are fighting each other in urban close quarters combat, they have modern for this time weapons and gadgets - automatic rifles, grenades, tanks, hand-held walkies-talkies, and other stuff.
But one side has this camo.
So, how the other side can deal with it?
UPD1: army, that uses this camouflage, is not affected by it. They have probably spent their childhood wearing these clothes, and are comfortable with looking at textures like this.
UPD2: The story occurs in Europe of 198X years of our world with slight alterations in history that occurred in the beginning of 19th century - there is still the Soviet Union, USA, East and West Germany, France. The technology level is near the same as ours in the 1980s - the IBM XT PC is the dream of hackers, internet = arpanet and bbs boards. So, no Google Glass or high quality augmented reality gadgets.
Army, that use this camo, is the invading one. I do not want to spoil the plot and explain how does it appeared, but they are almost ordinary humans, they use the weapons bought from USSR. They aim to conquer and control few major cities in Europe. It is not the ordinary army, it is some sort of special forces, so the usage of such camouflage was a great surprise to their enemy.
