Cats eye gradient thick frame glasses

Fits perfectly, not heavy as it seems to be (is metallic, not carbon fiber) but it's ok.
It's hard to use in the beginning because it filters all exactly as it says and you see different colors than original, but for long working sessions and after a few days it's easer to use

I have no understanding of how blue light works, I only bought this because my eyes felt tired all the time and I hold an office job.

Seems to work? I mean, if it's a placebo, it's a placebo that's really working for me so I'm happy with the outcome. Recommend this, since it does seem to block blue light a fair bit.
