Great review of our Vein Finder glasses in the Journal Emergency Medical Services

Oh Say Can You See ... That Hard-to-See Vein?
Seasoned paramedics excel at gaining IV access on the sickest patients, in the worst conditions and often in a moving ambulance. Attaining that expertise takes practice and persistence--with a bit of patient discomfort along the way. The new Vein Finder Glasses from VINO OPTICS 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! The Vein Finder Glasses 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.
