All LCD displays have color differences. There is software that can help you to adjust it to some standards, but in many cases this requires specialized tools to actually see the colors and provide adjustment settings to use with the display driver software. I have two Dell displays that are "in theory" identical (though different models manufactured at different times), and I have to go into the monitor configuration settings to adjust them to be as close to the same as I can, although I never get it quite perfect! As they say, sometimes good enough, is good enough... :-)

It sounds like you need to speak with a good ophthalmologist about this, and take the laptop for them to examine. Perhaps something with the colors, or other mostly imperceptible things are going on. Just one question. Is the backlight fluorescent based, or LED based? That will affect the colors, and also if there is a subtle problem with a fluorescent bulb, it could cause this sort of eye problem. Again, the eye doctor may be able to determine if this could be causing the problem, in which case you should be able to force the manufacturer to replace the light(s) under threat of suit for causing bodily harm (product liability)...
