What Light Is Best For Finding Veins?

If you’ve ever had blood drawn, you may have noticed that the phlebotomist always seems to have a hard time finding your veins.

To make the process easier, they often use a light to help them see your veins better. But what kind of light are they using?

There are actually several different types of lights that can be used to find veins.

  • The most common type is a transilluminator, which is a handheld device that uses a bright light to illuminate the skin. This helps the phlebotomist to see the veins beneath the surface of the skin more clearly.
  • Another type of light that can be used is called a Near-infrared vein finder. This device uses infrared light to detect the veins beneath the skin. It often works better than a transilluminator, but it can be more expensive.

Which Light Works Best for Finding Veins

Though both of the above-mentioned lights can be used to find veins, the near-infrared vein finder is often considered the best option. The reason for this is that near-infrared light is absorbed by hemoglobin, which is what gives blood its red color.

This absorption causes the blood to appear darker than the surrounding tissue, making it easier to see according to Find It Health. Near-infrared light is also scattered less than other types of light, so it produces a sharper image. Finally, near-infrared light is less likely to cause skin irritation than other types of light, making it more comfortable for patients.

Pros and Cons of Using Infrared Light for Finding Veins

As with any medical device, there are pros and cons to using infrared light for finding veins.


  • On the one hand, infrared light can penetrate through clothing and creams, making it ideal for locating veins in patients with dark skin tones or who are heavily clothed.
  • Additionally, infrared light is less invasive than other methods of vein detection, such as x-ray.


However, despite being a useful medical device there are also some drawbacks to using infrared light.

  • First of all, it is not always accurate, and veins can be missed if they are not directly under the light source.
  • Additionally, infrared light can be harmful to the eyes, so special care must be taken to avoid direct exposure.

Overall, infrared light is a useful tool for detecting veins, but it should be used with caution.

How to Choose the Best Infrared Vein Finder for Your Needs

If you’re looking for an infrared vein finder, there are a few things you should keep in mind to make sure you choose the right one.


One of the most important things to consider is accuracy. You’ll want to make sure that the device you choose is able to accurately detect veins.

Field of View:

Another thing to consider is the field of view. This is the size of the area that the device can see. A larger field of view is better, as it will allow the phlebotomist to see more of your veins at one time.

Ease of Use:

You’ll also want to make sure that the device is easy to use. It should be lightweight and easy to hold, and it should have a clear display.


Finally, you’ll need to consider the price. Near-infrared vein finders can be expensive, so you’ll want to make sure you choose one that fits your budget.

What Makes Infrared Light Vein Finder Stand Out of the Crowd

There are a few things that make infrared light vein finders stand out from the crowd:

  • They are less invasive than other methods of vein detection
  • They can be more accurate than other methods
  • They have a larger field of view
  • They are easy to use
  • They are affordable

Because of all these factors, infrared light vein finders are often considered the best option for finding veins than most the other methods.
