The researchers examined the effectiveness of FL-41 lenses (Blue-tinted and brown-red) on a group of 20 children diagnosed with migraines. At the end of the day, both lenses frequently reduce the migraines of these children.
  • The late 2000s: Prior to the late 200s, Dr. Bradley Katz believed that the FL-41 could be improved. His inspiration led to the new discovery of cells in the eyes, which contribute to the study of photophobia.

However, in the late 2000s, he altered the designs of the lens making them rose-hue and lighter. He also carried out research using the new lens on patients with blepharospasm (BEB). A condition that caused involuntary squeezing of the eyes. The experiment showed positive results. As the patients see improvement in their condition and squeezing of the eyes rapidly decreases. 

  • 2010: Doctors at Harvard University carried out research on migraine and all other kinds of headaches. From their findings, they figure out the effect of light on blind people and those suffering from migraines. The doctors also buttress the assertion that FL-41 could reduce migraines. 
  • 2016: Dr. Bradley Katz keeps improving the FL-41 lenses. His new lenses can help block harmful rays without distortion and darkness.
