The Vein Finder Glasses are an ingenious way to improve your IV access skills. They're designed by Caltech and Princeton scientists to enhance visibility of veins even under adipose tissue -- and they really do work! They are best used in bright sunlight at first so you can notice the difference with the glasses and without. Once you see the difference you can then use them with a bright flashlight and have nearly the same visibility.

The vein finder glasses have been a huge hit! I have done so well with them that my patients family members are asking for nurses to use them! I have even hit veins that no one else in the hospital could hit. This includes the anesthesia team!

My boyfriend is red-green colorblind, and after 30 years he is now able to see the full spectrum of colors which he has never experienced. He received the lenses yesterday and he has not taken them off aside from when he slept. Again, thank you so very, very much.
