> there is no good evidence that filtering blue light with spectacles...

That's likely referencing this recent review[1]. The products referenced don't actually reduce blue light by much, which you can confirm in the studies. The lenses look transparent, not amber in many cases. Which makes sense because they're meant for all day use, but it's just a marketing thing.

If you bought glasses in person in the last 10 years, they probably tried to upsell a blue light or "screen strain reduction" filter.

It's a stretch to hold this as evidence that blue light doesn't affect us.

Used to have extreme migraines. Any exposure to Fluorescent light would leave me mentally disabled within 10 minutes. So I could enter any grocery stores. Or go into work. Blue light filter glasses did little to nothing.

I got some FL-41 glasses that covered top and sides. I would be fine for about 2 hours under those lights. Eventually light leakage would get to me. But it made a drastic difference.

Fascinating, I would have thought it was the flickering of fluorescent that was getting you. I know CGA / EGA monitors with 60hz refresh rates really bothered me and gave me headaches and it was miserable to program at that time for me. It’s interesting that FL-41 glasses help you, I’m glad to hear you’ve found something that helps. That sort of pain awful and functionally frustrating.
