I'm torn. On one hand it doesn't seem prudent to block blue light ALL the time. On the other hand I seem to remember reading that cumulative blue light exposure is predictive for macular degeneration.
Note - Jack Kruse is controversial, so I'm not promoting this as fact, just that I personally think it has merit worth looking into. Do your own investigation.
Dr. Jack Kruse would say to block blue frequencies (the specific ones are in the 430-480nm range as I recall) all the time indoors. But not to block them outdoors. I wear these clipon's
all the time indoors (these block everything <490 nm). In fact Jack noted that in the 1920's an ophthalmologist published that his cataract surgery patients with metabolic disease got better after the operation (because of they eye's exposure to UV A frequencies). He said when he presented this to an ophthalmologist group, several came up and told him they'd experienced the reverse recently, as the lens inserts all block UV. So Jack said some of his followers needing the operation getting lenses maid in Germany that do not block UV.
Jack's perspective is we should get exposure without eye covering within the first hour of sun and also at noon to optimize circadian rhythm. We do need all the frequencies, but as presented by the sun, not the blue spikes of our screens, CFLs & LEDs, which are not balanced by the rest of the sun's natural spectrum.
He looks at himself as a "mitochondriac." He is easier to listen to at first than read. He notes that some of people who read his blogs are docs, so they are intentionally very technical. I initially found him "out there, " but as I've followed up, his physics based approach likely has merit, IMO. Here are some links - it takes work to delve into this. This interview
is perhaps a decent overview.site
, and podcasts.
Jack is controversial, & he would say that getting light, water & magnetism right is more important than food. Not that food doesn't count, but if you get the other's right, then you can be looser on food.
