My right eye was giving me lots of trouble(muscle around my eye) so I bought some Computer Glasses , orange tint and they cleared it up
If you want a nonscientific estimate- about half of people think it makes a difference, the other half doesn’t notice any change. It seems to be fairly subjective and you have to try it to know if you like them. The newer ones don’t have any yellow tint to them so at least it doesn’t mess up your color perception.
How about a black light blocking...oh never mind.
I remember the vids of Hillary wearing these glasses. Then...all of a sudden...YT took down medical academic studies of using these glasses for the use of Parkinson’s.
I had the lenses remade, in a different lens material to try to solve the refraction problems, and I instructed that I didn’t want any blue-blocking filter. They tried hard to sell the blue filter, making it sound like LED screens would make you go blind without it, but I still told them no. Yet, when I picked them up I noticed in the mirror that the lenses had a slight purple tint (which is what others see if you have a blue-blocking coating).
Ultimately, I kept those lenses because the refraction was much better and I was tired of going back. The blue filtering is more subtle than the original pair, but still introduces a slight yellow tint. Makes it impossible to calibrate my TV without removing my glasses.
I think it’s just a fad, and an excuse to pad sales with an additional charge.
My eyes are my only health problem, and my eye doc says “no more than 5 hours/day online. So I’d be very happy if those glasses actually work.
Anyone know?
I sort of rely on the fact that millions of years of evolution has the supposed problem covered. That and squinting.
well it is true that certain wavelengths are more harmful to your eyes, and some are more beneficial.
but as this is discussing a product for sale, there’s always a certain amount of hype behind it
just dont know about these particular glasses’ quality
at the same time, people now use red light therapy devices on theirneyes to help improve their vision
The following example article would have us believe that there is a problem with blue light versus eye health. Corrections, insights welcome.
"When researchers exposed the retinal to blue light, it triggered a reaction in which the retinal releases reactive oxygen species (ROS), poisonous chemical molecules that killed photoreceptor cells.” — Noel Kirkpatrick, Why Blue Light Is 'Toxic' to Your Eyes, Aug. 2018.
Until you click on them, the headlines here on FreeRepublic are blue.

Blue Blockers do help.
I remember a claim from several years back that CRT displays caused cataracts. I wonder what ever became of that. Science not settled?
It became so prevalent that the industry started to clamp down on false specs. At least from their competitors.
The specifications for cinema quality light sources are different than for what most of us can afford, and consumer projectors utilize many settings to bring a warmer, more cinematic viewing experience from a cheap projector.
There are multiple white papers and medical studies that will show whatever you want them to show, to back up a marketing perspective or ad campaign.
But the shorter wavelengths of light, especially wavelengths below 460 angstroms, become purple and then into the ultraviolet. It's these wavelengths that have been demonstrated to cause cellular damage.
Just as infrared wavelengths cause sunburns.
And yet I read books on my Kindle Fire in bed and fall to sleep.
