Abstract
Abstract An method for displaying to an observer a field of light, controllably variable in terms of color, size and intensity and a method of varying the color, size and intensity of the field of light in order to achieve a therapeutic effect in the observer. The field of light is displayed first at a long wavelength, low intensity small area, and slow pulse rate, and then at a relatively short wavelength, high intensity large area, and high pulse rate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
69 words
A method for achieving a therapeutic effect in an observer, comprising the steps of directing towards said observer's eyes a pulsing field of light controllable in terms of wavelength, intensity, area, and pulse rate in a sequence commencing with a relatively long wavelength, low intensity, small area and slow pulse rate and progressing to a light field of relatively short wavelength, high intensity, large area, and high pulse rate.
Claim 2
Independent Claim
69 words
A method for achieving a therapeutic effect in an observer, comprising the steps of directing towards said observer's eyes a pulsing field of light controllable in terms of wavelength, intensity, area, and pulse rate in a sequence commencing with a relatively long wavelength, low intensity, small area and slow pulse rate and progressing to a light field of relatively short wavelength, high intensity, large area, and high pulse rate.
Claim 3
Dependent Claim
28 words
The method of claim 1 further comprising the step of displaying to said observer immediately after said sequence, a field of light of intermediate wavelength, area and intensity.
