Simple Blue light considered dangerous.........................

[Chris Ryser]

Simpla Blue Light might be damaging to eyes

Nearly every eyecare professional (ECP) is familiar with the harmful effects of ultra-violet (UV) light. Not as many are aware that blue wavelengths of light are now being indicated as harmful to the eyes, too. Blue light, or more correctly the blue and violet portions of the visible spectrum, have been indicated as causing harmful effects to the eyes, similar to those of UV. Blue light also tends to scatter in the ocular media, especially in senior patients. This scatter reduces clear vision. The solution to this problem is to supply lenses that absorb blue wavelengths of light. Many manufacturers now provide this treatment with their plano and Rx sun lenses.

Chris, thank you for presenting this information. High Enegy Visible light is that very light you are referring to. I thought the small article in the SunSkills newsletter was excellent.

According to a white paper written in July, 2001 by J.M. Gallas, Ph.D., CEO of Photoprotective Technologies, HEV is of greater concern for AMD and loss of contrast sensitivity as one ages. One of the reasons discussed is that as a person ages, they produce fewer anti-oxidants that protect the retina/macula area (in addition to every other part of the body). Thus the need for addition of more antioxidants to our diet, which is only one of the reasons for our ocular vitamins, and changes in multivitimin requirements as we age.

This is a subject that I am extremely interested in, and beleive that we, as eyecare professionals need to be concerned with not just refraction of light (as in bending through lenses) but the filtration/absorption of the lenses as well. The materials, coatings and/or tints must all be included in order to offer protection to our patients.

The paper is very interesting, and was written as a result of the introduction of the Sun Rx Melanin lens by Vision-Ease. That lens has been basically replaced by the Coppertone lens, and I haven't researched the technology as much, yet, but intend to. Gary Falk, an optiboard member here, may have more information to share at this particular moment in time.

If I get time, and can offer more information, I'll post more.;)

Chris, can you repeat that link? I can't get it to work. Thanks!

I thought I'd go there and find all sorts of scientific studies about blue light but all I saw was one sentence stating blue light was considered harmful. The rest was all ads for sunglasses.

Barry is doing a ce on this very thing and vision ease has product out there to help (i don't work for them just enjoyed the ce)

the ce is also at 2020's mag

Here is a White Paper we have on the subject!

[chip anderson]

Do de folks that make this claim make blue-blockers or any other lenses?

[harry a saake]

so maybe we go back to the sixties and realize dr william crookes was right after all

Gary,

This is a great paper. I'll ask for permission to use the information from Vision Ease in an upcoming course.

Thanks,
Diane

As you are looking at me..............................

We do not make lenses..........but were the first lens dye producer to come up with a one step blue light blocking color in 1984. A further step was that it could be tinted over to look esthetically nice like, amber, chocolate brown and green.

Crazy-bout-optics and I both attended the seminar, very insightful and highly recommended.

Hi all! This is my first post here, and I currently work with Dr. Gallas here at PPT. We are still in business and promoting melanin lenses of all types including RX lenses as well. Feel free to drop me a line if you need further information. We can still be found at www.melaninproducts.com and www.pptworldwide.com :D

Whilst blue light has been implicated in retinal problems it may be better in some cases to ignore this as the effect of blue blockers can be be problematical in other ways.
Clinical judgement and knowledge is required (far too complex for a post)

Is it just me, or did the bird of paridise just take a big dump on my head??

[chip anderson]

Don't know what life would be like, surely not as pretty without the color blue. Think of life under brown skies, we already have enough brown water. All lovely ladies with beautiful blue eyes turned to another color, pure sacrilidge.

Band filters do change colours significantly - unlike broad spectrum tinted lenses. But colour constancy etc needs to be factored in.

Notch filters may also be used, but that is another matter.

How about the head lights on the newer cars ??, the one's that have a clearer, blue affect. When I'm driving towards a car that has those, no matter how far away they are, they give you a little head ache and make ya squint. Are those blue light? anyone know??, I think they should ban those..

Just my take, Ginny:)

Are they like the "Blue Light Specials" that KMART use to have?

;):cheers::cheers::cheers::cheers::D

[chip anderson]

Just last week I was driving and a lot of blue lights started flashing, I was innundated and stopped. Then this man in blue emerged from the blue light and wanted to give me a ticket! Seems my tag was expired.

Beware dem blue lights, dey can be expensive.

Ha Ha,

My question as bumb as it is, really is because I don't know, if they are harmful or not, I certianly won't look away, I might wreck the car, boy, my Husband would say " now tell me again, why did you wreck the car??:hammer::hammer::hammer::hammer:

[Ginster]

Thats ok Fezz. no offense taken, and Chip the blue men emerging from the blue lights can be pretty costley, we all have to watch out for the blue men, even in Vegas there a great act to see. WOW. we could go on and on about the blue effect, sorry to the origional poster for taking this in another direction.. And Fezz, I don't know how to PM or reply to a PM yet. Thanks though, your very thaughtful.:)

Ginster: I had a reading card showing the Midolothian highway many, many years ago. Always wondered where it was. Is there a Midolothian hiway leading to your location?

Theres a Midlothian Parkway, The main drag is Highway 287, that used to be called Midlothian Highway many, many years ago, the old timers tell me.Like 30 to 40 years ago as it runs through down town Midlothian, theres buildings here from 1865.

Thanks for asking, Ginny:)

Coppertone lenses discussed in the white paper presented earlier are not Blue blockers. As many of us know blue blockers greatly distort color. Coppertone HEV polarized lenses allow a small controlled portion of blue light to pass through which gives them excellent color perception.

Which makes them not full blue blockers ...............................

I did love my full blue blockers during the time I was waiting to have my cataracts removed.........what a soothing effect compared to any other color.
