An active lens cover for a device, such as a smart phone with a dual lens camera. The camera lens that faces the user and the camera lens that faces away from the user are not directly behind each other, but are slightly offset. The active lens cover is advantageously in the shape of a “U”, which allows a single cover to be used to protect both lenses. The offset arrangement of the two lenses allows the facing lens be exposed by sliding the lens cover in one direction, and the away lens to be exposed by sliding the lens cover in the opposite direction. When the lens cover is slid to expose the facing camera lens, the camera phone automatically turns ON and enters a pre-selected operating mode. When the cover is slid in the opposite direction to expose the away camera lens, the camera phone automatically turns ON and enters another pre-selected operating mode. The housing of the U-cover includes at least one sensor that tells the device's CPU what hardware to activate. In the preferred embodiment, the user is able to seamlessly switch between transmitting a video feed from either camera during a telephone call.

There is provided a binocular device, including a rigid mechanical body supporting two image sources (2, 4), one for each eye (6, 8) and two lensing devices (12, 14), one for each eye, the lensing devices having a first surface adjacent to the image sources and an opposite, second surface, each of the lensing devices projecting an image (16, 18) of one image source onto an infinite focal plane, and electronic means permitting modification of an image generated to an eye for adjusting the binocular alignment of the images. A method for aligning a binocular device is also provided.

The invention discloses a pair of bifocal contact lenses: one lens for dominant eye and one lens for non-dominant eye. Both lenses have an optical zone divided into a superior zone and an inferior zone. The superior zone of the lens for dominant eye is for distance vision correction while the inferior zone is for near or intermediate vision correction. The superior zone of the lens for non-dominant eye is for distance or intermediate vision correction while the inferior zone is for near or intermediate vision correction.

The embodiment of the invention discloses a binocular camera calibration method and device, an unmanned aerial vehicle and a storage medium. The calibration method comprises: controlling two lenses ofa binocular camera to obtain a first image and a second image in the moving process of a movable object; obtaining original parameters of the binocular camera; calibrating the binocular camera basedon the original parameter, the first image and the second image to obtain a first calibration external parameter; and acquiring position information of the binocular camera, and calibrating the binocular camera based on the position information, the first image and the second image to obtain a second calibration external parameter. A first image and a second image can be obtained in the moving process of the movable object. Calibration is carried out after the position information of the binocular camera is acquired, manual setting of a calibration plate is not needed, the relative position between the movable object and the calibration plate is not needed to be changed to calibrate the binocular camera, the calibration process of the binocular camera is simplified, manual operation is notneeded, and the calibration efficiency of the binocular camera is improved.

A pair of eyeglasses includes a frame, two lenses, two first magnets, two temples, and two fasteners. The frame includes two lens-holding portions and two magnet-seats. The lenses are held by the lens-holding portions, respectively. The first magnets are disposed at the magnet-seats respectively. The temples are connected with two sides of the frame respectively. The fasteners, each having a second magnet, are pivoted on the frame, and are rotatable with respect to the frame, so that the respective first magnet and the respective second magnet attract each other to fix the respective lens.

An automatic focusing mechanism of camera is composed of external frame including the hollow first cylinder with a circular hole, the first lens fixed to external frame and arranged coaxially with said circular hole, coil surrounding the first cylinder, the hollow second cylinder containing the first cylinder in it for relatively and coaxially moving, the second lens fixed in the second cylinder and coaxial with said circular hole, and an elastic part for linking the first cylinder with the second one. When a current flows through said coil, the second focus distance between both lenses is generated. If there is no current, the first focuse distance is held.

A system and method for collimating light emitted from a light source, such as a light-emitting diode (LED), is provided. The system and method includes two lenses, both lenses having a positive power for converging the light rays. In one example, the first lens is a hemispherical ball lens and the second lens is configured such that one surface conforms to the exiting surface of the first lens. The exiting surface of the second lens may be, for example, a Fresnel lens or an aspherical lens. In another example, the first lens may be a hemispherical or a hyperhemispherical ball lens. The second lens has an outer circumference having two aspherical surfaces. The inner portion of the second lens is in direct contact with the first lens. This configuration creates a dual-channel collimator.

The enhanced visual field prism optical apparatus includes a pair of eye glasses frames having the users prescription provided therein, if needed, and an enhanced field prism rotatably supported in front of at least one of the lenses of the frames. For binocular vision, a prism is rotatably supported in front of both lenses of the frames.

A pair of personalized eyeglasses comprises two lenses; a lens frame having a lens retaining portion for retaining the two lenses and two supporting rods extending from two sides of the lens retaining portion; and at least one texture area; texts on the texture area being on the lens frame or the lenses, or concaved into a surface of the lens frame or the lenses; or protruded from a surface of the lens frame or the lenses. The texts are at least one of names of users, address of users, ID numbers of users, phone numbers of users, birthdays of users, and data about the user's personal profiles; or the texts are about greeting, alerting, congratulations, anniversaries; or the data shown on the texture area is a section of article.
