Abstract

A system for exposure of eyes of a user to light is disclosed. That system comprises: a head mountable housing and at least one array of light emitting diodes disposed within the housing proximate to the eyes, and whereby light emissions are transmitted to the eyes. A controller is coupled to the light emitting diodes, and controls the intensity, duration, and sequences of the light emissions. Also provided is portable electrical charge storage cell, disposed within the housing, whereby an electrical current is supplied to the at least one array of light emitting devices.

Claims

1. A system for exposure of eyes of a human subject to light, said system comprising:

a head mountable housing;

at least one array of light emitting devices disposed within said housing proximate to said eyes, and whereby light emissions are transmitted to said eyes;

a controller coupled to said light emitting devices, whereby intensity, duration, and sequences of said light emissions are controlled; and

a portable electrical charge storage cell disposed within said housing and whereby an electrical current is supplied to said at least one array of said light emitting devices.

2. The system of claim 1 wherein said light emissions have wavelengths between about approximately 480 and 520 nanometers.

3. The system according to claim 2 wherein said light emissions have a peak wavelength of 500 nanometers.

4. The system according to claim 1 wherein said cell comprises a lithium polymer cell.

5. The system according to claim 1 further comprising an ambient light sensor coupled to said controller.

6. The system according to claim 5 wherein said controller is configured to adjust the intensity of said light emissions based upon data from said ambient light sensor.

7. The system according to claim 1 wherein said array is a plurality of said light emitting diodes disposed along a line.

8. The system according to claim 1 further comprising at least one lens disposed within said housing between said at least one array of light emitting diodes and said eyes.

9. The system according to claim 1 wherein said light emissions are directed by shields, disposed in said housing, to a region of the face of said subject encompassing said eyes.

10. The system according to claim 9 wherein said light emissions are substantially uniformly distributed over said region of face.

11. The system according to claim 9 wherein said region has adequate area to accommodate a variety of users having various inter-eyeball distances.

12. The system according to claim 9 wherein a distance between said light emissions may be adjusted.

13. The system according to claim 1 wherein said portable electrical charge storage cell is a battery.

14. An apparatus for photo-effective treatment of a subject, said apparatus comprising:

a casing;

first and second light emitting arrays;

a controller unit whereby the light emitted from the array is regulated;

a sensor whereby ambient light levels are measured, said sensor communicating with said controller unit;

a portable electrical charge storage cell disposed within said casing and whereby an electrical current is supplied to said first and second light emitting arrays.

15. The apparatus of claim 14 wherein said first and second light emitting arrays comprise light emitting diodes configured to emit light having a wavelength between 480 and 520 nanometers.

16. The apparatus according to claim 14 wherein said cell comprises a lithium polymer cell.

17. The apparatus according to claim 14 further comprising an interfoci distance adjustment.

18. The apparatus according to claim 17 wherein said interfoci distance adjustment comprises first and second racks disposed so as to move in opposing directions when actuated by a pinion disposed between said first and second racks.

19. The apparatus according to claim 17 further comprising a sliding track by which said arrays may be symmetrically repositioned.

20. The apparatus according to claim 14 further comprising an ambient light sensor communicating with said controller.
