What Do Nurses Use A Penlight For?

When nurses and Doctors shine a pen light into your eyes they are checking for the reaction they have from the light. This is crucial in deciphering a patients health. A non reaction from the pupils to light for instance means that the patient may very well have serious brain injury or trauma.

The other aspect of checking a patients eyes is to check that both eyes react the same way. If the light is being shine onto both eyes simultaneously then the eyes should act uniformly.

Lastly pen lights are used to look at the whites of the eye and condition vessels around the eye. All these pen lights can be specifically used in the healthcare professional realm.
