This pic needs the other eye included, so we can see if the pupil is equal, constricted, or dilated compared to the other eye. It's also impossible to tell whether the ptosis is one sided.

Assuming it's unilateral ptosis and miosis, however, I'd say Horner's.

EDIT: MAYBE Brushfield spots in the outer iris, indicating Down Syndrome?

Could you please answer how the picture of the eye can tell you a person is a non-smoker without any environmental factors, please?

I think Ycut was clarifying that this isn't in the context of a smoker or an environmental exposure. It was to offer context, not some deduction based on the image alone.
