Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
109 words
A reflective system for use in viewing one's own facial areas in the vicinity of the eyes, comprising first mirror means for collecting and reflecting rays of light emanating from said facial areas, second mirror means for collecting and reflecting said rays of light reflected from said first mirror means, third mirror means for collecting and reflecting said rays of light reflected from said second mirror means, and said first, second and third mirror means being mutually positioned with said third mirror means substantially facing said facial areas, with said first mirror means below said third mirror means, and with said second mirror means above said first mirror means.
Claim 2
Dependent Claim
109 words
A reflective system for use in viewing one's own facial areas in the vicinity of the eyes, comprising first mirror means for collecting and reflecting rays of light emanating from said facial areas, second mirror means for collecting and reflecting said rays of light reflected from said first mirror means, third mirror means for collecting and reflecting said rays of light reflected from said second mirror means, and said first, second and third mirror means being mutually positioned with said third mirror means substantially facing said facial areas, with said first mirror means below said third mirror means, and with said second mirror means above said first mirror means.
Claim 3
Dependent Claim
29 words
A reflective system according to claim 1 wherein said first mirror means is larger than said second mirror means which is in turn larger than said third mirror means.
Claim 4
Dependent Claim
18 words
A reflective system according to claim 1 wherein at least one of said mirror means is a magnifier.
Claim 5
Dependent Claim
61 words
A reflective system according claim 1 comprising a case, said first and second mirror means being hingedly connected to said case for swinging movement into a collapsed position over said third mirror means with one of said first and second mirror means at least partially disposed between said third mirror means and the other of said first and second mirror means.
Claim 6
Dependent Claim
24 words
A reflective system according to claim 4 comprising means incorporated in said case for holding said mirrors in fixed relative positions during use thereof.
Claim 7
Dependent Claim
22 words
A reflective system according to claim 4 comprising means for adjusting the angular position of one of said mirrors in said case.
Claim 8
Dependent Claim
76 words
A reflective system according to claim 1, comprising a case, first hinge means connecting said first mirror means to said third mirror means for swinging movement of said first mirror means between a fixed operative position and a collapsed position over said third mirror means, and second hinge means connecting said second mirror means to said third mirror means for swinging movement between a fixed operative position and a collapsed position over said third mirror means.
Claim 9
Dependent Claim
30 words
A reflective system according to claim 7 wherein said first and second hinge means comprise abutment means for setting said first and second mirror means in said fixed operative positions.
Claim 10
Dependent Claim
20 words
A reflective system according to claim 7, comprising means snap-fitting at least one of said mirror means to said case.
Claim 11
Independent Claim
190 words
A method of observing one's own eye while manipulating an opthalmic contact lens thereon, comprising the steps of positioning a first mirror to one side and in front of said eye at an angle such that light rays reflected from said eye are reflected from said mirror at an angle of less than ninety degrees from the angle of incidence, positioning a second mirror above and in front of said eye at a position to intercept and reflect said rays reflected from said first mirror away from said eye at an angle of less than ninety degrees from the angle of incidence, positioning a third mirror between said first and second mirrors in a direction facing toward said eye and intercepting said rays reflected from said second mirror, and observing the image of said eye and said lens reflected to said third mirror by said first and second mirrors while manipulating said lens in said eye, whereby said eye is observed from a direction different from the line of sight of said eye, thereby facilitating the holding of the pupils in an elevated position during the manipulation of said lens.
Claim 12
Independent Claim
190 words
A method of observing one's own eye while manipulating an opthalmic contact lens thereon, comprising the steps of positioning a first mirror to one side and in front of said eye at an angle such that light rays reflected from said eye are reflected from said mirror at an angle of less than ninety degrees from the angle of incidence, positioning a second mirror above and in front of said eye at a position to intercept and reflect said rays reflected from said first mirror away from said eye at an angle of less than ninety degrees from the angle of incidence, positioning a third mirror between said first and second mirrors in a direction facing toward said eye and intercepting said rays reflected from said second mirror, and observing the image of said eye and said lens reflected to said third mirror by said first and second mirrors while manipulating said lens in said eye, whereby said eye is observed from a direction different from the line of sight of said eye, thereby facilitating the holding of the pupils in an elevated position during the manipulation of said lens.
Claim 13
Dependent Claim
26 words
A method according to claim 10 wherein p1 said rays of light are reflected from said mirrors at acute angles relative to the angles of incidence.
Claim 14
Dependent Claim
26 words
A method according to claim 11 wherein said line of sight is displaced from the line of observation by an angle between about 30° and 35°.
