Q - I wanted to ask that when I sometimes play video game I suffer from irritation fatigue and agitation does that screen helps if I play and put it on my tv ( use ps4 and xbox 360 and I have a cellphone that's the only thing that is wireless..)?
Both the PS4 and the Xbox emit constant RF radiation for the WIFI communication and for the wireless remote control.

It is most likely that that the iphone you are using also emit almost constant RF radiation when the Data connection, WIFI and Bluetooth are turned ON.
My guess is that the headaches you experience while playing is caused by the above RF radiation.
In order to minimize the exposure I guesses to use the PS4 when the remote controls are connected via USB to the PS4 (never tried it on PS4, on PS3 it worked) and turn off the WIFI connection.
Regarding the XBox, I don't know how to operate it with minimized radiation emission.
In addition, turn of the WIFI, 3G/4G data and Bluetooth on the iphone or just put it on "flight mode".
If the headaches are caused by the RF radiation, you should feel better when all the wireless is off.
If you still feel something, then and only then , the LCD screen protection might help (http://www.4ehsbyehs.com/rf-protection/LED-LCD-screen-protection-film)
The EMF emission form the screen is usually just a fraction of what you get from all the above devices.
You can buy an EMF meter and see the radiation your self - http://www.4ehsbyehs.com/emr-meters/cornet-ed78s
I hope this info helps.
