I have been getting a burning sensation in my eyes, like a heat wave and then i feel nauseated. what can cause this?

Surface problems: Burning in the eyes usually is due to dry eyes or a lid condition known as blepharitis. It is safe to try warm compresses over the eyes when it burns and use of artificial tears sold over the counter. If it persists, an eye doctor may prescribe prescription strength medications, so see an ophthalmolgist if the above doesn't work.
