Abstract
Abstract The present invention is an apparatus for producing and delivering high-intensity light to the eyes of a subject to modify the subject's circadian phase. The apparatus includes a support for positioning the apparatus above the eyes of the subject, a light generator for producing a cool, high-intensity light which is radiated to the eyes of the subject, and a power source coupled to the apparatus for supplying power to the light generator. The support of the invention is preferably a visor which does not obstruct the subject's vision when positioned on the head.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
153 words
A bodily worn apparatus for producing and delivering light to the eyes of a subject for treatment of physiologic and psychiatric disorders affected by exposure to light, comprising: support means for removably positioning said apparatus on the head of the subject vertically above the eyes of said subject, said support means affording the subject a generally unobstructed visual field when said support means is positioned on the head of the subject above the eyes; at least one cool, high-intensity, light generating means including a cold cathode lamp supported by said support means for producing a cool, high-intensity light; and a power source coupled to said light generating means for supplying power to said light generating means. wherein the temperature of said cool, high-intensity light produced and radiated to said subject by said light generating means is comfortable to said subject, allowing said subject to wear said apparatus for an extended period of time.
Claim 2
Dependent Claim
153 words
A bodily worn apparatus for producing and delivering light to the eyes of a subject for treatment of physiologic and psychiatric disorders affected by exposure to light, comprising: support means for removably positioning said apparatus on the head of the subject vertically above the eyes of said subject, said support means affording the subject a generally unobstructed visual field when said support means is positioned on the head of the subject above the eyes; at least one cool, high-intensity, light generating means including a cold cathode lamp supported by said support means for producing a cool, high-intensity light; and a power source coupled to said light generating means for supplying power to said light generating means. wherein the temperature of said cool, high-intensity light produced and radiated to said subject by said light generating means is comfortable to said subject, allowing said subject to wear said apparatus for an extended period of time.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1, wherein said support means is a visor having a bill and a headband.
Claim 4
Dependent Claim
19 words

Claim 11
Dependent Claim
32 words
The apparatus of claim 1, further comprising a shield disposed between said light generating means and the eyes of said subject for filtering out harmful radiation while transmitting substantially all visible light.
Claim 12
Dependent Claim
17 words
The apparatus of claim 1, wherein said light generating means generates a light of approximately 10,000 lux.
Claim 13
Dependent Claim
23 words
The apparatus of claim 1, further comprising a means for prescribing the timing and intensity of a light treatment schedule using said apparatus.
Claim 14
Dependent Claim
24 words

Claim 15
Dependent Claim
17 words
The apparatus of claim 13, further comprising a means for connecting said apparatus to said control means.
Claim 16
Dependent Claim
114 words
A bodily worn apparatus for projecting light to the eyes of a subject, comprising: a visor having a bill which extends over the eyes of the subject and a headband which is adapted to be positioned about the head of the subject; a cold-cathode fluorescent lamp mounted on said bill of said visor for producing light; a power source disposed on said visor for supplying power to said lamp; and means for coupling said lamp to said power source; wherein the temperature of the light produced and radiated to said subject by said cold-cathode fluorescent lamp is comfortable to said subject, allowing said subject to wear said apparatus for an extended period of time.
Claim 17
Dependent Claim
114 words
A bodily worn apparatus for projecting light to the eyes of a subject, comprising: a visor having a bill which extends over the eyes of the subject and a headband which is adapted to be positioned about the head of the subject; a cold-cathode fluorescent lamp mounted on said bill of said visor for producing light; a power source disposed on said visor for supplying power to said lamp; and means for coupling said lamp to said power source; wherein the temperature of the light produced and radiated to said subject by said cold-cathode fluorescent lamp is comfortable to said subject, allowing said subject to wear said apparatus for an extended period of time.
