I wear blue light filtering glasses for working at my desk. You can order them with varying intensity, and there’s some visible differences with higher strength, but often you don’t really notice the difference after a while.
The idea with them isn’t necessarily to filter out all blue light, it’s to filter out some of it, to hopefully reduce some of the strain over a long period, not necessarily to block all blue light at once. It’s also useful on nights when I’m working before bed, because one thing they have proven is that blue light fucks with sleep cycles.
They’re not safety goggles, they’re more like sun screen. It’s gonna get through, but not as much, and that makes a difference over long time frames.
