Among the medical must-haves for phlebotomists, nurses, caregivers, and other medical professionals are infrared vein finders.
Using these simple vein light devices will help you save time, reduce wastage of materials like needles and syringes, and avoid the trauma, stress, and pain that patients with hard-to-find veins experience when you are trying to stick them. Examples of these patients include babies, children, the elderly, and those with dark skin.
In this vein finder review, we present the most affordable infrared vein finders as well as the best paramedic vein glasses on the market. But first off, some background.
What are the Benefits of Vein Finders?
If you usually perform cannulation or venipuncture, you know that some people have veins that are difficult to detect.
According to various statistics, medical professionals that do not use a vein light are likely to take patients through most sticks. Patients that go through most sticks are stressed and experience a lot of pain. Moreover, the safety of the procedures reduces with each additional stick. For this reason, nurses and other medical professionals should use vein finders.
Below are the benefits of using vein finders:
- Helps to save time
- Reduces wastage of midline trays, PICC, syringes, and needles
- Reduces unnecessary stress and pain on both the patient and caregiver
- Infrared vein light devices are painless and non-invasive
- Makes veins to be more visible 
How Do Vein Illuminators Work?
You can easily see the veins of most people. However, in others, the veins can be difficult to see. For example, you may struggle to see the veins on people with dark skin or those with fatty tissue.
Infrared vein finders work by emitting infrared rays through LED bulbs. The hemoglobin and Oxygen molecules in the blood readily absorb the infrared light. 
When you plan an active infrared vein locator on the skin, the blood veins become visible to the naked eyes because the hemoglobin absorbs the infrared light and becomes darker in appearance.
Check the video below of the Veinlite vein finder to see how it makes it easy to see veins that are difficult to detect.
Guide to Buying a Vein Finder
Before buying a vein finder, there are a number of things you should keep in mind. In particular, consider the following:
Do you need to illuminate facial veins?
Some portable vein light devices cannot illuminate the small facial veins. If you will be illuminating facial veins in the course of your work, you would need a device like the Vivolight vein finder.
Should you buy a vein finder for babies/children or adults?
Generally, the best vein finders on the market can be used for both adults and children. However, some devices are specifically designed for use on children or adults only.
For example, the Wee Sight Transilluminator is an excellent vein finder for neonates. This tiny vein finder has fewer LEDs and would be perfect for use on toddlers and babies. The device is one of the best vein finders for pediatric nurses.
