Does your iris shrink if tired?
Yes, the iris can appear to shrink or constrict when a person is tired. This is primarily due to the pupillary response, where the pupils may become smaller (miosis) as a reaction to fatigue or low light conditions. However, this change is more about the size of the pupil rather than the iris itself physically shrinking. Overall, tiredness can influence the size of the pupil, affecting how the iris appears.

When light rays pass through your pupil, the muscle called the iris (colored ring) makes the size of the pupil change depending on the amount of light that's available.

Likewise, if there is very little light available, the pupil will enlarge to let in as many light rays as it can. Just behind the pupil is the lens and it focuses the image through a jelly-like substance called the vitreous humor onto the back surface of the eyeball, called the retina.
