Why are my pupils big?
My students tend to have large low-lit areas a bit, but not so much. I can not explain. I am a healthy cross-country skiing, wrestling and track. I think it might be the case because I saw someone here say they are healthy. I think people who are in athletics, the cause slow heartbeat that can withstand strenuous activity, and his eyes are opened to take in the light. idk
The student's role is to regulate the amount of light falling on the back of the eye. In situations of all students under the light-dilate to let in more light so that your eyes can decipher images you are viewing. In very bright student of contracts to limit the amount of light that makes the eye. You are normal.
