What Causes Unusual Eye And Pupil Control Abilities?

Hi. I developped some weird ability, and I'd like to know if it's common. I gained quite a great amount of control over my eyes. My pupils, actually. I can alter their sizes, and even their shapes (only a little bit) just by self control. I feel like I have a muscle to play around with it, and the more I train it, the more control I gain over it. Right now, I'm able to do a weird trick, which enable me to view in a kinda Imax 3D by pulling colors, or something like that, but everything being mega blurry. I read that the university of Helsinki is doing a research on voluntary eye control without the use of emotions. If you could tell me it's possible, I'd contact them. I just showed my dad, and he kinda freaked out. Thanks, and sorry for my low level English.
