Without these glasses and the light, I was struggling with tasks required for my job
I am a Neonatal Nurse Practitioner and use them for placing umbilical lines in premature infants.
As I have gotten older, I was having trouble putting in umbilical lines (a special IV catheter in the vein & arteries) and intubations (placing a breathing tube in the trachea) on premature infants. I am also a quilter. I found out about the lens from my dental hygienist and the next month just happened to go to a quilt show in Hampton, VA and you had a booth there. I tried them out and they are wonderful! Without these glasses and the light, I was struggling with tasks required for my job. The light is a must for anyone who purchases these also!
