Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
72 words
A method for relaxing the accommodation of the eye, said method comprising: flashing a source of light to produce a light output, placing a lens between the eye and source of light at a distance other than the lens focal length with respect to the source of light, refracting the light output with said lens to form a nonfocused visual stimulus, and directing said non-focused stimulus onto the retina of the eye.
Claim 2
Independent Claim
72 words
A method for relaxing the accommodation of the eye, said method comprising: flashing a source of light to produce a light output, placing a lens between the eye and source of light at a distance other than the lens focal length with respect to the source of light, refracting the light output with said lens to form a nonfocused visual stimulus, and directing said non-focused stimulus onto the retina of the eye.
Claim 3
Dependent Claim
49 words
A method as in claim 1 wherein said directing step comprises passing at least part of said non-focused stimulus through an aperture towards the eye to increase the eye''s depth of focus and thereby make attempted eye accommodation less effective in changing the non-focused image on the eye''s retina.
Claim 4
Dependent Claim
79 words
ApparAtus for relaxing the accommodation of an eye, said apparatus comprising: source means including a flashing source of light, a lens located between the flashing source of light and the eye, said lens being spaced a predetermined distance substantially different than one focal length of the lens with respect to the flashing light source to thereby defocus the image of the light source for generating a non-focused visual stimulus, and means for directing said stimulus onto the eye''s retina.
Claim 5
Dependent Claim
79 words
ApparAtus for relaxing the accommodation of an eye, said apparatus comprising: source means including a flashing source of light, a lens located between the flashing source of light and the eye, said lens being spaced a predetermined distance substantially different than one focal length of the lens with respect to the flashing light source to thereby defocus the image of the light source for generating a non-focused visual stimulus, and means for directing said stimulus onto the eye''s retina.
Claim 6
Dependent Claim
17 words
Apparatus as in claim 3 wherein said flashing source of light produces a green colored light output.
Claim 7
Dependent Claim
22 words
Apparatus as in claim 3 wherein said means for directing comprises: an aperture disposed between the eye''s position and said source means.
Claim 8
Dependent Claim
28 words
Apparatus as in claim 5 further comprising a lens disposed between the aperture and the eye''s position for focusing the aperture substantially within the pupil of the eye.
Claim 9
Dependent Claim
94 words
Apparatus for relaxing the accommodation of an eye, said apparatus comprising: a flashing light source for producing a light output, an optical lens disposed at a position other than its focal length with respect to said flashing light source for refracting said light output into a non-focused image thereof, and an aperture disposed between the eye and said optical lens, whereby the eye views said non-focused image through said aperture to thus increase the eye''s depth of focus and make attempted eye accommodation less effective in changing the non-focused image on the eye''s retina.
Claim 10
Dependent Claim
94 words
Apparatus for relaxing the accommodation of an eye, said apparatus comprising: a flashing light source for producing a light output, an optical lens disposed at a position other than its focal length with respect to said flashing light source for refracting said light output into a non-focused image thereof, and an aperture disposed between the eye and said optical lens, whereby the eye views said non-focused image through said aperture to thus increase the eye''s depth of focus and make attempted eye accommodation less effective in changing the non-focused image on the eye''s retina.
Claim 11
Dependent Claim
38 words
Apparatus as in claim 7 further including another optical lens disposed to focus said aperture substantially within the pupil of the eye whereby the eye effectively views the non-focused image through the aperture directly at the aperture location.
Claim 12
Dependent Claim
17 words
Apparatus as in claim 7 wherein the light output from said light source is green in color.
Claim 13
Independent Claim
75 words
A method for relaxing the accommodation of the eye, said method comprising: producing a flashing light output from a light source, refracting said flashing light output to form a non-focused image thereof, and placing an aperture between the eye and the non-focused image whereby the eye views the non-focused image through the aperture which increases the eye''s depth of focus, making attempted eye accommodation less effective in changing the non-focused image on the eye''s retina.
Claim 14
Independent Claim
75 words
A method for relaxing the accommodation of the eye, said method comprising: producing a flashing light output from a light source, refracting said flashing light output to form a non-focused image thereof, and placing an aperture between the eye and the non-focused image whereby the eye views the non-focused image through the aperture which increases the eye''s depth of focus, making attempted eye accommodation less effective in changing the non-focused image on the eye''s retina.
Claim 15
Dependent Claim
18 words
A method as in claim 10 further comprising: imaging said aperture substantially within the pupil of the eye.
