Questions & Answers

Q: What is the function of the pupil?

The pupil's function is to regulate the amount of light that enters the eye by dilating or constricting based on the surrounding lighting conditions.

Q: What controls the size of our pupils?

The size of our pupils is controlled by the muscles in the iris and the intensity of the light present. The muscles adjust the pupil size to regulate the amount of light reaching the retina.

Q: What causes pupils to dilate?

Pupils dilate in response to low light conditions. This allows more light to enter the eye, improving visibility in dimly lit environments.

Q: Why do pupils constrict?

Pupils constrict in bright environments to limit the amount of light entering the eye. This prevents the eyes from being overwhelmed by excessive light.

Summary & Key Takeaways

  • The pupil is a hole in the center of the iris that allows light to enter and be focused on the retina.

  • Two factors, the muscles in the iris and the amount of light present, control the size of our pupils.

  • Pupils dilate in low light conditions to allow more light in and constrict in bright environments to limit the amount of light entering.
