Yes you can see the ON without dilation. Likely you went in for a "medical" exam rather than a "complete eye exam" that includes dilation/refraction.
Use the search feature and read about "Dry eye treatment"

So if I had optic nerve swelling, he would have seen it by just looking into my naked eye. What is the ON? Why do they dilate them?
I thank you for your quick response. Bless you
Sorry, I realize was ON is. Would he see edema or papplimona (sp) with the naked eye?
ON swelling doesn't cause eye to burn. The naked eye is not much help for most of the eye exam the structures are just too small
