Helps with headaches.
I have had my Felix Gray's since 2018 and since starting to wear them I have seen a significant improvement in eye-strain and migraines. I was experiencing watery eyes and a strained eye feeling which made it hard to focus my eyes at time, and I attributed this and an increase in migraines to constant screen viewing - if I'm not on my laptop I'm probably on my phone and vice versa. If I forget to wear them for a week or two, I can tell a difference. About to order a second pair, after I get an actual eye exam to make sure blue light is the only cause.
