Abstract
A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.
Claims19
In combination with a camera used by a person, said person having a sighting eye and a nonsighting eye, an improvement comprising:
- (a) a partial shielding means for occupying a portion of the nonsighting eye's field of view sufficient to:
- (i) cause the image in the portion of the sighting eye's field of view transmitted through the camera's sighting aperture to dominate and suppress the image in the corresponding portion of the nonsighting eye's field of view, and
- (ii) maintain unobstructed, usable vision in at least a portion of the nonsighting eye's medial field of view;
- and
- (b) a supporting means for supporting the partial shielding means before the nonsighting eye.
A partial eyeshield, for use by a person in conjunction with a single eye sighting device, said person having a sighting eye and a nonsighting eye, comprising:
- (a) a partial shielding means for occupying a portion of the nonsighting eye's field of view sufficient to:
- (i) cause the image in the portion of the sighting eye's field of view transmitted through the single eye sighting device's sighting aperture to dominate and suppress the image in the corresponding portion of the nonsighting eye's field of view, and
- (ii) maintain unobstructed, usable vision in at least a portion of the nonsighting eye's medial field of view;
- and
- (b) a supporting means for supporting the partial shielding means before the nonsighting eye.
A method of using a single eye sighting device, for a person, said person having a sighting eye and a nonsighting eye, which method comprises the steps of:
- (a) positioning the single eye sighting device before the sighting eye;
- and
- (b) positioning before the nonsighting eye a partial shielding means for occupying a portion of the nonsighting eye's field of view sufficient to:
- (i) cause the image in the portion of the sighting eye's field of view transmitted through the single eye sighting device's sighting aperture to dominate and suppress the image in the corresponding portion of the nonsighting eye's field of view, and
- (ii) maintain unobstructed, usable vision in at least a portion of the nonsighting eye's medial field of view.
