BPI Winter Sun™
Chase The Winter Blues Away!

Helps your patients feel better neurologically
Following the recent developments in the diagnosis and treatment of Seasonal Affective Disorder, BPI introduces its Winter Sun™ to help chase the blues away.

Seasonal Affective Disorder
As described by Norman E. Rosenthal, M.D. in his book 'Winter Blues', Seasonal Affective Disorder (SAD) is a condition which can cause severe depression in its victims depending upon the time of year. For these people, according to Dr. Rosenthal, “Seasonal transitions trigger extreme changes in mood and energy, and produce sadness and despair.” So far the greatest form of relief has come in the form of Light Therapy which artificially extends the amount of “day light” to which a SAD patient is exposed, thereby imitating the longer days of the happier, summer months.

Antidepressant effects
In addition to the amount of light exposure, studies have shown that the color of the light is important in determining antidepressant effects. According to researchers at the National Institute of Mental Health in Bethesda, MD, green light, to which the eye is most sensitive, has been proven to be most effective in treating SAD patients. With this in mind, Dr. Herbert Wertheim of Brain Power, Inc. proposed the use of BPI’s Winter Sun™ lenses as a means of optimizing the antidepressant effects of any light exposure.

BPI Winter Sun™ lenses
Winter Sun™ lenses have a light, golden-yellow tint with the highest UV protection available, so they can be worn indoors or out, at all times. Since 1982, Winter Sun™ glasses have been worn with positive results in Sweden, Norway and many other areas of the world where the winter season brings short days, long months and an atmosphere primed for depression. The warm, transparency of Winter Sun™ was designed to offer clarity to the viewer by bringing all colors into the eye’s most comfortable range of light, as outlined by the researchers in Bethesda. In this way, the lens keeps the eye safe from the sun’s harmful rays and improves vision while being of psychological benefit to all, not just those afflicted with SAD.
