In the healthcare industry, the ability to quickly and accurately find veins is critical. From inserting IVs with medication to drawing blood for lab diagnostic tests, the veins of the body are essential to nearly every medical profession.
In both emergency situations and clinical environments finding a patient’s veins may be difficult. This can be due to illness, dehydration, age, or excessive weight.
Vein finders were created to help those who work in healthcare find their patient’s veins quickly and accurately by mapping out the locations of the veins. Vein finder glasses are more portable than the typical vein finder and can be worn all day long, which can be handy when emergency situations arise with little time to hunt down equipment.
They are also useful in clinical training in order to show students the physical locations of veins before they begin to practice. The best vein finder glasses are comfortable enough to be worn for long periods of time and are durable to the rigors of healthcare work.

Best Vein Finder Glasses to Purchase for Medical Professionals:
Originating from the lab that discovered that an enhanced color vision allows humans to see blood under the skin and patented by two scientists, the VINO OPTICS Vein Finder Glasses is the top of the line in Oxy-iso technology.
With Oxy-Iso technology, oxygenation signals under the skin are amplified and isolated by the tinted lenses and enhanced to be shown as fluorescent. The tinted lenses are even powerful enough to help out those who are red-green colorblind. They have the added benefit of being able to fit over the frames of prescription glasses as well as having anti-static, anti-fog, and anti-scratch coating.
- The patented design was created by scientists from Caltech and Princeton.
- The tinted lenses are strong enough to assist those with red-green colorblindness and enhance the veins under the skin.
- These glasses are able to fit over regular prescription glasses while still remaining comfortable.
- They provide UV protection and have anti-fog, anti-static, and anti-scratch coatings.
- The VINO OPTICS company offers a 30-day refund or replacement guarantee.
What is a Vein Finder?
Vein finders are a medical device that assists healthcare workers in finding the location of veins. This is performed with various technologies, but it is commonly done with infrared or LED light. This is based on the fact that light is absorbed differently by blood than by surrounding tissues.
For example, when an infrared light is projected onto the skin, the light is absorbed where there is blood or veins, and thus the veins are shown as a darker color in contrast to the rest of the skin.
Vein finders can help healthcare workers establish IVs, easily draw blood, perform cosmetic procedures that require the location of veins, and efficiently perform blood infusions.
What Are the Types of Vein Finders?
While there are numerous different types of vein finders, they each tend to fall into one of three categories. These categories are an infrared light projected vein finder, an infrared light screen display vein finder, and a LED transmitting vein finder.
An infrared light projection vein finder is the most popular vein finder in use today. It uses infrared light to create a map of the veins and then projects that map back onto the skin. This process gives the healthcare worker a map of the veins in a particular area. Many vein finders of this type come with a stand or support to hold the device in place so that no one else is needed strictly to handle it.
An infrared light screen display vein finder is similar to the infrared light projection vein finder in that it uses infrared light shown onto the skin to highlight the blood and veins. The difference comes in where the map of veins is displayed. This vein finder includes a screen that the vascular map can be displayed on.
This is good to use when in clinical training or another event that requires several people to need to see the veins at once.
Then there is the LED transmitting vein finder. These vein finders come in compact sizes and are suitable for individual clinical use. They use the bright light from the LEDs to illuminate the skin in order to see the vein better when rolled over it. This type of vein finder also is used, after finding the vein, to stretch the skin, close the vein, and lift it to prevent the vein from rolling.
What Are Vein Finder Glasses?
Vein finder glasses employ the use of tinted lenses to highlight the veins in the body and make them stand out against the skin. They make once hidden veins appear florescent so that healthcare workers can find them easily.
This type of vein finder can be more useful to those in healthcare than other devices because they can be worn regularly without a problem and can function as protective glasses. With vein finder glasses, there is no need to lug equipment around.
All that is needed are bright lights in the room being used. As a secondary benefit, vein finder glasses have been shown to help those with red-green color blindness to see all the ranges of color.
How Do Vein Finder Glasses Work?
Human color vision has been found to have evolved into seeing the oxygen fluctuations that occur in the blood. This is due to the red-green color variations in our vision that pick up on the oxygenation signals that the blood gives off.
Vein finding glasses work with these visual variations by amplifying the color that the oxygenation signals that veins give off. This is done by the tinted lenses blocking certain narrow bands of light that translate to visual noise when trying to see fluctuations in the blood’s oxygen levels.
Vein finder glasses can help nurses, EMTs, doctors, and phlebotomists accurately find veins quickly and painlessly. They help to raise confidence in both the healthcare worker and the patient by making IVs, blood work, and infusions effortless.
All-day comfort, as well as additional protection from UV rays, fog, and scratches, are important things to keep in mind when trying to find the best option for vein finder glasses for you.
