Nausea with MacbooK Air Retina

So i just picked up today a Macbook Air w/Retina and it gives me major Nausea. I also have a 16 inch MacBook pro no nausea. I cant modify the refresh rate on the MacBook air, i can on the pro. I have been looking for solutions as i want to carry the lighter device. How can you modify refresh rate, on the MacBook air? What settings can be used to eliminate it? No i don't have medical issues, it is only happening on the air and i was just at the eye doctor and did my annual check up. That seems to be what everyone says, you have a medical condition.
