A visual field observation training lens is disclosed, along with corresponding training eyewear. An associated method for training visual observation toward a designated field of view is provided.

An eyewear with an adjustable indication of vision field comprises an eyewear frame having a right side and a left side opposite the right side, a shade positioning assembly attached to one of the right side and the left side of the eyewear frame, and a shade attached to the eyewear frame at the shade positioning assembly. The eyewear frame has a pair of lens areas positioned between the right side and the left side and adapted to be aligned with a pair of eyes of a user. The shade is formed of a transparent material. The shade is movable along the shade positioning assembly to a plurality of positions among which the shade covers a varying amount of one of the lens areas.

The present invention relates to a system for user adjustable optical field of view alteration. The system includes a support member, an optical system, and an adjustment system. The support member releasably secures the system to a user's face, including a frame over the user's nose and two temples extending back from the frame over the user's ears. The optical system is positioned on the frame substantially in front of the user's eyes. The optical system displays an altered field of view to the user's eyes that is different that the direct field of view seen by the user. The adjustment system adjusts the altered field of view by rotating a portion of the optical system with respect to the support member about an axis of rotation.

A system and method for user-initiated occlusion of vision includes an electrically or electromagnetically controlled lens disposable in front of one of the user's eyes. The lens may be controlled by a trigger device including a sensor that may be activated by various motions of the user's body. The trigger device may communicate with the lens wirelessly. The lens may be incorporated in a wearable apparatus or head gear having a variety of forms.

The present disclosure relates to a pair of noise reduction glasses for video shooting. A frame of the glasses is provided with at least one camera unit, and an image processor is electrically connected to the camera unit and a main control unit respectively and is configured to process an image signal from the camera unit and transmit it to the main control unit; and a WiFi module is electrically connected to the main control unit and is configured to be wirelessly connected to an external terminal and transmit an image captured by the camera unit in real time. In the present disclosure, the camera unit is provided on the frame, and the WiFi module is added to transmit a real-time image, so that other users can watch a real-time scene in front of the noise reduction glasses for video shooting through a live broadcast by means of smart terminals, which meets the needs of the users for live viewing, supervision, teaching and recording, and the convenience of use is improved. In addition, the glasses of the present disclosure collect external shooting noise through a sound pickup, and then form noise-reduced audio through a sound pickup and noise reduction circuit and output it to a noise reduction earphone to realize an active shooting noise reduction function, which provide effective protection for the shooter's hearing.

A customizable eyeglass system for use in any remote situation, and which is ideal for use in third-world countries or areas where electrical power and typical machinery for manufacturing eyeglasses is lacking. The system includes a frame with receivers for the temples to connect into and lock into place. A pair of customizable lenses is connected to the front of the frame. The lenses can be rotated to dial in the correct prescription for the patient and then locked into place as well. Thus, the invention corrects near and distance vision while also correcting astigmatism. If adjustments need to be made, the patient can easily unlock the lenses, rotate them to a proper orientation for proper sight, and then lock the lenses into place again. The replacement lenses can be used with optical enhancement scopes such as telescopes, firearm scopes, and binoculars.

An eyewear with an adjustable indication of vision field comprises an eyewear frame having a right side and a left side opposite the right side, a shade positioning assembly attached to one of the right side and the left side of the eyewear frame, and a shade attached to the eyewear frame at the shade positioning assembly. The eyewear frame has a pair of lens areas positioned between the right side and the left side and adapted to be aligned with a pair of eyes of a user. The shade is formed of a transparent material. The shade is movable along the shade positioning assembly to a plurality of positions among which the shade covers a varying amount of one of the lens areas.

An optic focusing cover. The optic focusing cover includes a cylindrical body with openings at both ends. A corrective lens is disposed within the cylindrical body such that it covers the entire opening. The corrective lens is capable of further magnifying the telescope. A cap is attached to a first side of the cylindrical body, the cap is capable of going from an open to a closed configuration. A second end of the cylindrical body is configured to be accepted by a telescope.

Aiming glasses can be used for finding a line of aim when shooting firearms and pneumatic weapons, as well as in archery, billiards, golf, and curling. The aiming glasses include an optical part in which aiming guides can be moved and rotated relative to a frame in order to align the center of the guides with the visual axis of the eye, which passes through the center of the fovea and the target, and to vertically orient the guides. The results are improved at aiming accuracy and greater versatility of the aiming glasses for use in different types of sport. A further technical result is that of enabling a sportsperson to cultivate a reproducible afterimage of the aiming guides at the start of a line of aim.

Embodiments include a disposable shooting target. The disposable shooting target can include a substrate, a first ink layer, a second ink layer, and a third ink layer. The first ink layer can contact the substrate. The second ink layer can be disposed over the substrate. The second ink layer can include a first color that defines a first portion of a target image. The second ink layer can also include a second color that defines a second portion of the target image. The third ink layer can be disposed over the second ink layer. The third ink layer can be partially translucent. The third ink layer can partially obscure portions of the target image. Other embodiments are also included herein.
