Try all the glasses. You will feel differently with each color. If for example you have a headache, try each color until you find one that takes it away. You may not like a particular color, but this may be the color you need, so try them all. It is up to you to decide what you need, and you really are the best judge of that.
Color is nothing more than light energy.
You only receive the affects of the color while you are wearing it. Once you stop wearing it you are no longer affected by it. Color Therapy Eyewear in no way intends to suggest that these glasses be used us a substitute for Licensed Medical Care. In cases of physical, emotional or mental illness, always seek professional medical assistance. Knowledge is our greatest ally.
