Pupil Size? 5 Best Medical Pen Lights 2019 [Disposable To High Quality]

Best Medical Pen Lights

Why A Medical Penlight Instead of a Flashlight?

The Look: For most of the tests that a doctor, a nurse, or an EMT would perform, any flashlight would work. Since doctors and nurses are in a professional setting and usually want to have something that does not look like the typical tactical flashlight, medical penlights are a top choice. The best medical penlights look professional rather than rugged and are usually available in colors other than black. For those looking for pediatric penlights you can find penlights in many colors and some of the disposable penlight packs even come in a rainbow pack. There are also pens with lights available, but they do not usually have as good of a flashlight.

The Size: A medical pen torch is designed for the medical professional so they are easy to fit in a pocket or have attached to a clip board.

The Low Lumen Setting: Many non-medical flashlights do not have a setting low enough for the everyday checkup. It is nice to have a very low lumen setting so patients do not feel like they are being blinded. With that said, the downfall of most of the cheaper medical diagnostic penlights is that they only have a low setting, so they are almost useless in most other circumstances. If you do not care about a low lumen setting, check out our best penlight article.

The Pupil Gauge: Many doctors, nurses, EMTs, or paramedics probably do not need a pupil gauge, but it might be nice to have. Many lights that are dedicated medical penlights have a pupil gauge printed on the side of them. For those of you that are not sure what this is for, I will explain a little later.

Uses For A Medical Pen light

Pupillary-Light-Reflex-optThe Pupil Test: The reason why doctors, nurses, and EMTs carry flashlights is to do a pupil test. So, what can the pupil test tell us? First, doctors look to see if your eyes constrict if a light is shown in the them. The doctors or nurses will keep track of how much constriction you have with a pupil chart. Second, does the swinging flashlight test, moving the flashlight from eye to eye every few seconds to check that both eyes, have the same response and that your eyes both react regardless of which eye has the flashlight in it. This is called the consensual constriction test. A light test can also be used to diagnose and discern the severity of a concussion and is often used with patients that are passed out to check reflex and brain function. Using a pen torch for the eye examination is easier than a large light.

Looking through drawers/cabinets/closets: Doctors and nurses have to keep track of so much stuff that they are often looking through drawers, cabinets, and closets to find what they need. It is important to have a small flashlight handy for these small tasks.

Going into patients rooms without turning on the lights: Doctors and nurses are constantly going through patients rooms in the middle of the night while patients are sleeping. A nice respectful doctor or nurse would use a flashlight to get around instead of turning on the lights at 3 a.m. A little bit of courtesy goes a long way with patients that are already having a bad day.
