Feeling dizzy when looking at display

Question

Hi there, I am now on my third Mac. This is the first one with a LED display (Macbook Pro with matte display) I noticed that I feel dizzy after working with my Mac (every time now for a month). I did not think much about it until I read in a national paper that all LED lights were exchanged in a government building. All people working there were feeling dizzy and complained about headaches.
Is there anybody who has the same "issues"? Comments will be highly appreciated.

As eww points out, Apple have only ever used LCD displays in their notebook computers. The recent difference is that Apple have changed to backlighting the LCD screen using LEDs. Formerly, florescent lamps were used, sometimes referred to as CCFLs (cold cathode florescent lamp).
Both CCFLs and LEDs, as used in LCD backlighting, are strobed as a means of dimming control. But with the differences in operating characteristics, the strobing is more pronounced with LEDs when compared with CCFLs, and that seems to have pushed a small percentage of the user population over the tipping point with respect to experiencing some form of discomfort using the notebook screen.
bluebirdnl, one thing you might try is running the screen at full brightness using the built-in brightness controls and then controlling dimming using a program like Shades as was referenced by another poster in this thread. That would eliminate the strobing effect, and you could see if that is the source of your sensitivity or not.
