What is penlight?
Penlights are tiny spotlights that resemble the pens we use on a daily basis for writing.
Penlight is a useful examination tool for doctors, particularly for small body parts like the mouth, nose, ears, and eyes.
They frequently employ it for the pupil test, a physical examination technique used to determine whether pupils contract or remain dilated in response to light.
The most popular tool for measuring pupil diameter now has a light source and is a penlight.
One pupil contracts in reaction to light, whereas the other either doesn't contract at all or contracts more slowly.
