There is another kind of "light" therapy... It has to do with color.
Chiros typically use that type.
I have heard of this, but don't know much about it:

These SAD light visors were designed to provide light in the proper wavelength,
and with NO UV...and at certain strength (LUX) to stimulate the receptors
in the retina for melatonin. This resets your biological clock. The one I have was made by Physician Engineered Products (designed by doctors).

You know I used to use BlueBlocker sunglasses.. they turn everything orange.
Now those were weird, but they really helped with glare, and they sharpened
images while driving. Really nearsighted people, like having the blue removed.
Now I use Eagle Eyes type, and the color distortion is less. I have to drive ALOT...so I don't like arriving at work, to a visual task job, tired already!

I have not had any problems with the weird green, since the first day. The first day was a "shock" I have to admit.

Also I bumped up my B-complex to 100mg 3 times a week, in addition to
my P-5-P once a day. You need the B's for making neurotransmitters, esp
B6. This I am sure is helping with rapid responses. Perhaps it would be slower without the vitamins. (there is no mention of vitamin support in the directions---I thought that up myself).

The green does set off a complimentary pink reaction, so when wearing the visor, white fields look pinkish. But you know, the 1/2 hr goes by really
quickly...I just log on here, and poof...they shut off in no time!
The horrible stiff neck/upper back I was having, seems to be melting away as well...this low grade pain was very wearing for me..and discouraging.

This being old all of a sudden is a bummer... truly a bummer!
At least my sense of humor is returning!
And my husband OFFERED to come with me shopping and then go to
a nice gourmet lunch too...how rare is that? Help me shop?
