blue light blocking glass and the benefits

[SOL]

I was using blue light blocking glasses that only blocked 50% of the blue light. I thought they blocked 100%. Then i bought a new pair that blocks 70% to 80%. Oh my, what a difference. I tested them for 9 hours. I usually spend less time on the computer but testing is essential and the difference was like day and night I will now look for glasses that block 90% or more. As after 9 hours of usage, i did not feel any eye fatigue

I bought a SpyderX Pro to calibrate monitors for some people at work and I calibrated mine too. At first I hated it, within an hour I actually liked it. I didn't believe how blue and overly bright my monitors were set.

I'd like to try some of these glasses for computer eyestrain. I see lots on the usual sites. They are unclear (to me at least) on how much of the blue light that we are concerned with is blocked. For example, some on Joom say "All of our lenses block 100% of UVA, UVB and UVC rays, and harmful blue light to 400nm" whereas some on Amazon say "99.9% Blue Light Blocking Glasses (380-410nm)".

A random website about computers & blue light says "The typical wavelength of blue light falls between 450 and 490 nanometers", which is outside the range of both of these.

Am I getting too involved?

I have been using f.lux on the computer for a while...
