Measurement of UV-A Radiation in Car Windows to Better Understand the Risks of Cataract and Skin Cancer

 

uvcardThis study published in the prestigious medical journal JAMA Ophthalmology in May 2016, the first of its kind in the United States, looks to build awareness of the risk UV-A damage from driving motor vehicles but also has relevance to other types of windows (homes, schools, office buildings, etc) that make people vulnerable to the effects of the sun.

Dr. Brian and his daughter analyzed 29 automobiles from 15 manufacturers and tested the UV-A blockage from both the front and side windows and found that the average percentage of front windshield UV-A blockage was 96% which was 25% higher than the side-window UV-A blockage. According to Dr. Brian, “Our study found that front windshields offered consistent protection as they are constructed with a clear layer of plastic. The reason for this is to make the windshield “shatter-proof” in the event of an accident. This plastic layer largely contains the UV-A protection. Side windows generally do not have this layer.“

A BRIEF NOTE ABOUT DR. BRIAN

Throughout his highly respected career, cornea specialist Dr. Brian has never wavered with his integrity and dedication to always do the best for each and every patient - even in the face of adversity and peer pressure. Case in point: when he developed a procedure to treat a cornea condition known as Keratoconus. While other eye surgeons were entrenched in performing invasive and painful cornea transplants, Dr. Brian invented a new non-invasive procedure that prevented needing cornea transplants. He was shocked by the medical establishment being unwelcoming to his innovation because, as he later found out, his new procedure was preventing other eye surgeons from performing their lucrative cornea transplants. Dr. Brian persisted, went against the grain and didn’t give up because he believed in himself and in his procedure as it was in the best interest of patients. Eventually, he crossed paths with U.S. Olympic bobsled driver Steven Holcomb who had Keratoconus and became so depressed over it that he tried to commit suicide. Luckily, he survived. The United States Olympic team and his coaches found Dr. Brian and sent Steven to see him. Dr. Brian restored his vision to 20/20 which enabled Steven later win a historic Olympic gold medal for United States in bobsled - the first in 62 years! As a result, Dr. Brian was later invited to give a prestigious TEDx talk about his integrity and dedication to patients. You can watch his moving and inspiring TEDx talk here.
