Hey gang, I'm doing some research on this here company: https://www.migraineshields.com/
I've been tasked with comparing the blue light blocker they use(BluTech, i guess?), that being said, is anybody familiar with them? How does it compare to say, a Prevencia?
Do they use a specific lens to help mitigate migraines? (Besides from the blue blocker, which I'm not really sure about).

Thank you!
