Why were my eyes dilated?

Question

I hadnt been to the opticians and i dont do drugs .yet my pupils were at first really tiny and then they went HUUGE !! I read somewhere that being aroused can make this happen - sounds strange though . Is this the reason? or is there another explanation ?

Answer 1

There are plenty of explanations but the simplest is how much time elapsed before you noticed larger pupils and what was different about the lighting in the room when you looked in the mirror a second time.

Answer 2

You might have really fancied the optician, but its more likeley that the dimmer light for looking at your eyes caused it.
