Hi John... any plans to do a video on blue light?
Thank you!
LOL
No, no, and aw hell naw.
That's like doing a video on religion or politics...
A billion opinions and almost no actual facts/real studies to work with.
I leave blue light to a personal choice.
Perhaps the Talking Heads said it best:
I'm checking them out
I'm checking them out
I got it figured out
I got it figured out
There's good points and bad points
But it all works out, you know I'm a little freaked out

Just between us - not like I'd post this on a quasi-public forum or anything - but - I think anyone being honest must reach the same conclusions.
If you stand to profit from the whole blue light = death ray thing then it gets so much easier to believe...
I don't really stand to profit from it, I would put most of the people I work with in high end AR anyway. But if they are on the computer for long periods of the day I usually go with the high end AR with blue-light protection. Whether it works or it doesn't isn't, it won't hurt their vision. I haven't seen anything that says blue light AR coatings are worse than non-blue light coatings at preventing glare or increasing visual acuity.
I don't think you need to take a strong stand on it either way, go with what the customer wants. I show the customer the blanks of both coatings, and explain that it blocks around 30% of the blue light. I find men especially seem to not like the reflection of the blue light coatings and tend to go with the other options.
I do think there is something to be said for what Barry is saying, the psychosomatic response is strong. If people think blue light will reduce their eyestrain it may very well do that. Whether that's because blue light works or it doesn't who knows. I would definitely like to see some long term studies before I start saying things with authority though, I 100% agree with that.
What blue light coating do you offer? Is there a spectral transmission chart showing it blocks 30% of blue light? What wavelength range are you counting as "blue light"? Seems like that would be an awfully orange viewing experience.
I think you would be hard pressed to find any thinking optician who would say "I can 100% prove to you there is and never will be any harm from blue light!". No one is saying that. But the burden of proof lies with those making the claims of efficacy, and so far no proof has been provided.
Now, we all know placebo is a real thing. So my question is, would you, or any blue light prescribing doctor(you know the ones, they write it on every single Rx), be comfortable just telling your patients the lenses you are making them reduce eyestrain, are better for computer work, etc. (whatever the current claim of blue light lenses are), while making them lenses that are non-blue light lenses.? Just the same AR that you would use for anyone opting out of the blue light lenses. I think a lot of people would have a problem with this, patients and ECPs. I would guess that some would see it as lying to the patient and even unethical. I see no distinction between:
Making blue light lenses for people that have no scientific evidence for their claims, and telling the patient they are beneficial.
and
Making non-blue light lenses for people, and telling them they are beneficial against blue light.
For the record I would not do either of these things.
Come on John, are you sure you don't want to make a video about blue light? It would be so much fun. Comedy? Tragedy? War Epoch?
I honestly tell people I work with that we don't have any long term studies to show how harmful blue light is, we suspect that it isn't good but there isn't the science there to say for sure one way or another. If they still want the blue light then fine, but I am not pushing it or trying to talk someone out of it either. And I don't stand to make a profit either way, I charge the same for both high end AR coatings.
I am pretty apathetic to both sides of this.
We have plenty of people coming in specifically to buy blue light lenses, I am not talking them out of it. If they are convinced it works why would I?

I tell people what I believe the truth is, which is we don't have any long term studies that show how harmful blue light is. Is that factually wrong? I let people draw their own conclusions from that fact. I am not going to try and dissuade them from their opinion. They could very well be right, I don't have the facts to say either way.
When people bring up blue light I also make a mental note to talk to them about sunglasses.
I run a business, I don't see why you cannot be both a sales person and an optician.
I think blue light is more "dangerous".... outside than in front of a pc or a smartphone.. better a good quality pair of sunglasses?
