Dr. Glen worked with the Flying Samaritans to provide vision care to those in need in Mexico. After experiencing this work where used eyeglasses are measured, categorized and reused, he created a mathematical formula to help identify the closest prescription in the inventory to that needed by a given patient.
Dr. Glen earned the Academic Achievement award for Optics and was also named a Nikon Scholar while at SUNY State College of Optometry. Other awards included the Leadership Award, and membership in both Beta Sigma Kappa and Gold Key honor societies.
He served as Trustee, representing his school internationally in the American Optometric Student Association, in which he eventually served as Vice President, Editor, and President, representing over 4,000 student Doctors of Optometry around the globe.
Dr. Glen's formula for recycling eyewear was later the subject of clinical research at the University of California at Berkeley, School of Optometry. UC Berkeley is rated, along with the school where Dr. Glen completed his doctorate at the head of his class, as one of the top two schools in the world for training Doctors of Optometry.
The University Optometric Center, where Dr. Glen completed his clinical internship, is the largest outpatient eye and vision care clinic in the world.
