      Can control of "Involuntary" functions be harmful?

      I can control my iris contraction/dilation of each eye individually. These multi-unit smooth muscles are considered an involuntary muscle group. Involuntarily reacting to light changes.

      It would be nice to know if this is harmful, because since I’ve learned to control them they will sometimes react on their own without light changes due to passing thoughts. Almost like my brain is continuing to test its control over the function.

      I doubt it is dangerous, after all there are many drugs routinely used in medicine that dilate or contract the iris, letting in too much or too little light to the eye. The only symptom usually is the temporary loss of acute vision as long as the pupil size is not optimal.

      Also, the brain keeps constantly altering the pupil size according to emotions and other phsyiological factors. If you stare your eyes in the mirror, you will notice the size of pupils constantly adjusting. This happens with all people.

      I’m sorry i think i misunderstood, did you just say that you can control the contraction and dilatation of your iris voluntarily??? Voluntarily as in "OK, pupil, contract! Good boy!Here’s a cookie."???

      yeah
      i think its a bit harmful. 🙁
      it won’t if you are clever enough and know when to do what and secondly i suggest you should stop testing if you can control them or not.
      but its a good achievement 😉 🙂
      harmful, why?
      okay just imagine excess of light entering the eye and you don’t let it contract. what would happen? think about the rods and cones

      So, do you think it is or isn’t harmful? 😆
