Blue light and eye damage I've done some research about light therapy, and it seems that while blue light does have some success with SAD and with mid-winter energy drain, it also at high brightness levels can degrade the retina which is the major cause of age-related macular degeneration. Light therapy is generally within the 470-525 range, but only that above 500nm is safe to eyes. Does anyone know the frequency # of this product?

So it is less than the 500m the other poster mentioned above ... so you're saying this is a bad thing, right? I sure don't want to hurt my eyes.

Also, there is a program called F.lux which is free and will change the tint of your computer monitor and android phone /tablet when the sun sets (you can even set it to switch gradually). This is perfect for those of us who still need to use a computer at night but also need to sleep at a reasonable time after it.

I realize this is rather too late but it may help others... The light given off by the GoLite is in the 440-480nm range. Its peak output, that it to say the brightest wavelength, is at 464nm. White light also contains these wavelengths, but along with other colors which aren't necessary for melatonin suppression. This is how the GoLite can be less bright overall (in terms of a lux measurement) than other sad lights.

The issue is UV light. https://www.macular.org/ultra-violet-and-blue-light quotes 400nm as the cut off.

This blu lite seems to actually work. I noticed a difference the first day at 15 minutes low intensity. This is the third day. The previous days I experienced an upsurge in energy. Felt focused. Got stuff accomplished. I am 66 suffer from SAD but also avascular-necrosis. Conscequently I am normally not too mobile. The past two days I have been extremely mobile. Today, I sort of craved the 30 minute session with the lite. I hardly even notice that it is there. Placebo? I don't think so. There has got to be some physical effect going on here. I just hope it is not damaging to my eyes, even though one would not look directly into it. I am a believer. This blu lite seems to actually work.

Looks like R. Jensen answered your question. I can only add that I checked with my eye doctor to ensure it was safe for my eyes and he said no problem since it was in the blue green spectrum. It has worked wonders for my SAD issues! I just went to Costa Rica and was able to get over jet lag and adjusted to the new time zone very quickly.

I pulled out the package insert, and it appears to function only in the blue wavelengths of around 425-500. It states "the Syrcadian Blue provides maximum therapeutic intensity, while minimizing the normal side effects experienced with high brightness, full spectrum light therapy. Full spectrum side effects include blinding glare, headaches, dizziness, and even nausea'. Hope this helps you!

It's bluish compared to an incandescent. It's not as blue as natural sunlight (whose color temperature is 6000 k, but is actually "cooler" perceptually than "warm" white , which is the color of incandescents and halogens -- yellowish -- and is 2700-3000k). This light is probably around 4000k, which, compared to an incandescent, is cold and harsh. It says 3000k on the box but that's -- to put it nicely -- inaccurate.

The low winter sun seems to be shortening the daily light life span. I hope it will return to normal after the winter. I have about 6 mos. on it thus far and until now was satisfied with the light's performance.

Yes, as long as it is 10,000 lux or greater it is recommended for treatment of SAD. It has helped me throughout the winter season. 30 minutes, daily in the am -Sit under at a 90 degree angle. It has been a life saver.

I keep it on in the mornings while at work. If it is dark outside, I immediately turn it on. You only need 30 min per day. I keep it about 3 feet away from me in the corner of my eye. It doesn't interfere with my vision at all. The bulbs are fluorescent, and I'm on my second season now with it. It really and truly does work, will give you more energy waking up and knock the blues away through the day. Warning! Don't use it at night as it may keep you awake.

As far as I can remember, my B-Cure emits a fixed wavelength of 808 nm. It seems to work well. Other laser companies say a combination of 660 and 905 nm can address deeper tissues. It's hard to know what works best.The green LED contact light periodically fails on mine (it's "on" this week), but, the red glow of the actual laser is still fine (visible in a dark room) - after 15 months of use (twice daily at 35 minutes per session) on my right knee.-Brian

The instructions say not to use it more than once a day. It is probably because the lights may harm your eyes more than they would harm your skin though. Using once daily in the am worked over the course of a week with noticeable improvement seen in two days for us.

I spoke with my optomistrist, and she indicated that she knew of no eye condition that would prevent a person from using this type of light. She actually encouraged it. She did recommend that each person check with their own eye doctor, and if there was any discomfort at all, to discontinue use. She also advised against staring right in the light, but rather, let it shine on the side of your face.

I would have to say yes, each color light is effective for different things.I want to add that the red and yellow lights have helped a lot with my seasonal depression as well. I try to do a daily rotation using all colors. I'm extremely satisfied with my results.

Certain wavelengths of light have beneficial effects on the skin and can be harnessed for therapeutic applications. Light wavelengths are often referred to using their associated color and include blue (405-470 nm), green (470-550 nm), red (620-660 nm) and near infrared (NIR) (700-1000 nm) lights.

OMG! Too Much! In the instructions it says only one light per (25 min) session and to let your skin heal for 24 hours in between sessions. Since I have acne and rosacia, I use the blue light primarily, then I use the red light for collagen production, every third night. I don't have hyerpigmentation anymore, so I do not use the aqua light. More is not prudent with this technology. You can create more damage by inducing inflammation. Be patient and use one light per night. The acne results you will see within a few nights... The other two lights, you will see beginning results around a month (on average and based on other customers and friends). Good Luck! OMG! Too Much!

I am very sorry, I don't know the answer to your question. I do not notice any difference in my eyes when I take this product. It was prescribed for me because I have age related "dry" macular degeneration. This product has been shown to help delay the onset of "wet" macular degeneration which is seriously bad for one's eyesight. I am 79 and have had "dry" macular degeneration for approximately 12 years. When my eyes are dry, I use an artificial tear product by Bausch & Lomb. Wish I could help you but only know about how this applies to me. I would think that ICaps wouldn't hurt but certainly do not know if they would help.

As far as I am concerned, EyePromise Restore is the best product on the market to restore the macula. My numbers went from .05, which is extremely low, to .49, normal being .50, in 18 mos. My eye care provider and I are so very happy with the results and I cannot recommend it more highly. Thank you for your interest. I wish you the best.

It doesn't appear to be very blue. It seems like the lower brightness settings have very little to no blue, and blue increases a little bit as you raise the brightness settings. I know the blue thats found in computer screens disrupts my sleep, and I haven't found that to be the case when I use this light (even when used as a night light). The higher settings, I've found, do give you energy similar to sunlight...Tried out the alarm this morning, it works like a charm

Some things require more independent, organic treatments and vitamins and so on. But macular degeneration is bad news, the kind of thing where you are better off probing deeper into the medical establishment and clinical trials. The only folks I know of who found a "miracle" on that one were folks who found a good but complicated clinical trial. For milder eye aging, Costco sells a product a bit like OcuVite but far more credible... I forget the two ingredients... much more of the "L" ingredient in Ocuvite, and a good amount of the "X" or "Z" ingredient. No time to look it up this morning. A little orange bottle at Costco. (Not Lutein and CXananthan? Somehting like that.) Some things require more independent, organic treatments and vitamins and so on.
