Warm Regards

Please do not look at this for too long without blinking, you may go blind.

It is becoming dark.
My eyes can see
But I follow the light
So I do not have to be
Lost in the night sky

The heat
Oh, the heat
Does not leave me beat
But, alas, the cold destroys me

I warm the faces of the world
I sing with the blowing wind
I watch the day become unfurled
Then I travel to the next morning

Who am I?
You cannot look at me for too long, I can damage your eyes
The sun am I!
Am I the sun?
Yes
