Why our eyes blinked when we come from dark room to bright light?

 You had observed many times when you moved  directly from darkroom to bright light your eyes blinked. had you ever thought why it happens ?

   When we are in a dark room our eye pupil gets expanded to see object clearly. when come to a dark room our pupil gets expanded automatically to see the object clearly. and when we moved directly from darkroom to bright light due to increase in size of  pupil extra light go into our eyes that's why our eyes get blinked for some times. after some time it's size start decreasing.


 You had also observed that when you come from bright light to a dark room.you will not able to see any object in a dark room, but after some time you can see all the object  because it take time to increase your pupil size in dark room.

 Our pupil size always resizes depending on the light brightness.

Thanks You
