This is an interesting phenomenon called as photic sneeze
We generally sneeze to get rid of something that is irritating the inside of our nose, such as dust, pollen, or viruses. The body uses lots of nerves and muscles to coordinate this protective reflex. Although no one knows exactly why photic sneezes happen, there are some theories. A popular one is that a sudden flash of bright light causes the nerve signal leaving the eye (along the optic nerve) to trigger a nearby nerve (trigeminal) that goes to the nose, thereby causing a sneeze. Another theory suggests that bright light causes the eye to make more tears, which drip into the nose and trigger a sneeze.

I sneeze specifically when looking at the sun, not by looking at a flourecent light or any other kind, Only the sun, and coincidence that it happens JUST when I look up, is highly doubtful. The sun is amazing, because I love sneezing.

What I want to know is how people can actually believe this. An allergy to sun is one thing, though the people I knew who had this problem usually broke out in a rash.
Sneezing comes from particles of dust or whatever flying into your nose and tickling your nose hairs basically.

It is a parasympathetic reflex that about 20% of the population shares. It is triggered by contraction of the pupil in response to abrupt exposure to bright light.

Because light is usually upwards and when you tilt your head up all the dust particles settle in your nose and you sneeze.

Oh, this one is easy: it doesn't. Seiously. I have never sneezed when looking at light. You may, but I doubt seriously it was caused by light. But, more importantly here, don't write in second person.

that is unusual, but maybe the tear formation washes the make up into the nose to which you are allergic??!!

Science is still perplexed on this one
