Does having dilated pupils increase your field of vision?

What does having dilated pupils imply for your vision?

No. Field of vision is determined by the placement of your eyes (if they were back further on the side of your head, you'd have a larger field of vision, but a smaller area of binocular vision). Pupil dilation increases the amount of light hitting the retina, but it doesn't increase field of vision, magnification, etc. It's akin to turning up the brightness of the light source on a microscope.
