Abstract: 1. An interactive light field device, comprising: a transparent lens; a matrix of light carrying devices positioned on or in said transparent lens, said matrix of light carrying devices being essentially transparent to a human eye; a light sensor connected to said matrix of light carrying devices for sensing light reflected from said human eye; a light source for generating light to be delivered to said human eye by said light carrying devices; means for coupling said light carrying devices to said light sensor and said light source; and means for projecting light from at least a portion of said light carrying devices in said matrix of said light carrying devices into said human eye at an acute angle less than 90 degree  with respect to a pupil of said human eye. 2. The device of claim 1 wherein said light carrying devices in said matrix are selected from the group consisting of optical fibers and optical wave guides, 3. The device of claim 1 wherein said light sensor is selected from the group consisting of a photo detector array and a charge coupled device. 4. The device of claim 1 wherein said light source is selected from the group consisting of white light emitters and light emitting diodes. 5. The interactive of claim 4 wherein said light source includes light emitting diodes which can emit colored light selected from the group consisting of red, green, and blue. 6. The device of claim 1 wherein said light source emits light at a wavelength ranging between 500 nm and 560 nm. 7. The device of claim 1 further comprising a means for pulsing said light source. 8. The field device of claim 1 wherein said means for projecting light is selected from the group consisting of a prism positioned in a light delivery path at an end of a light delivery device and an angular formation at an end of said light delivery device. 9. The device of claim 1 wherein said light source and light sensor are positioned in an arm connected to said transparent lens, and further comprising a power supply positioned in said arm for providing power to said light source and light sensor. 10. The device of claim 1 further comprising a computer controller connected to said light source and said light sensor for controlling the intensity and duration of light delivered by said light source and analyzing light detected by said light sensor. 11. Eye-wear having an interactive light field, comprising: a frame; a transparent lens positioned in said frame; a matrix of light carrying devices positioned on or in said transparent lens, said matrix of light carrying devices being essentially transparent to a human eye; a light sensor connected to said matrix of light carrying devices for sensing light reflected from said human eye; a light source for generating light to be delivered to said human eye by said light carrying devices; means for coupling said light carrying devices to said light sensor and said light source; means for projecting light from at least a portion of said light carrying devices in said matrix of said light carrying devices into said human eye at an acute angle less than 90 degree  with respect to a pupil of said human eye; and an arm connected to said frame for holding said frame on a human head. 12. The eye wear of claim 11 further comprising a temperature measuring device for measuring a temperature of said human eye. 13. The eye wear of claim 12 wherein said temperature measuring device includes a temporal temperature sensor and an infrared temperature sensor. 14. The eye wear of claim 11 wherein said light source and said light sensor are positioned in said arm, and further comprising a power source for said light source and said light sensor. 15. A method for subjecting a human eye to an interactive light field, comprising the steps of: placing a transparent lens in front of a person's eyes; projecting light from a matrix of said light carrying devices positioned on or in said transparent lens into said human eye at an acute angle less than 90 degree  with respect to a pupil of said human eye; and detecting light reflected from said human eye. 16. The method of claim 15 further comprising the step of pulsing said light during said projecting step. 17. The method of claim 15 further comprising the step of determining a position of a pupil of said human eye. 18. The method of claim 15 further comprising the step of analyzing patterns of detected light from said detecting step. 19. The method of claim 15 further comprising the step of providing an alertness or sleepiness warning in response to said patterns of said detected light.
