The invention belongs to the technical field of liquid crystal display, and particularly relates to a liquid crystal lens and liquid crystal glasses. The liquid crystal lens includes an electrode unit and a liquid crystal layer, and liquid crystal in the liquid crystal layer is equivalent to a Fresnel lens of which the focal length is adjustable under the effect of the electrode unit. According to the liquid crystal lens and the corresponding liquid crystal glasses, through the control over the electrode unit, liquid crystal in a liquid crystal box achieves effects equivalent to a concentric circle of the Fresnel lens, and the glasses are thin, light, small and exquisite in structure, can be matched with different vision changing situations of the human eyes, are used for solving various vision problems such as shortsightedness, farsightedness, astigmatism and presbyopia and become a kind of glasses capable of being worn permanently, so that people overcome troubles of changing glasses; further, even entertainment functions such as emotion hints can be added, and more abundant communication means are provided for people.

An apparatus and method for treating floater problems of the eye. In some embodiments, a magnet is non-invasively held in place against the face, and in particular, over the lower eyelid of the patient over an extended period of time, in order to control the position of the floaters and to stimulate the eye to better focus. In other embodiments, the device is included in eyeglasses that hold the magnet next to the lower eyelid. In some embodiments, the magnet is placed next to the lower eyelid. In some embodiments, the magnet is replaced by or supplemented with electrical stimulation. Some embodiments use a permanent magnet, while others use an AC or DC electromagnet. In some embodiments, a tapping device or heating device is included. The electro-magnetic force, tapping, and / or heat are controlled with a chip, circuit, and / or switch. In some embodiments, the device is placed under the skin.

A method is provided for the treatment of vision problems in a subject suffering from one of various forms of albinism, including, for example, oculocutaneous albinism types OCA1a and OCA1b, as well as ocular albinism type 1, resulting from mutations in the GPR143 gene, as well as the OCA2, OCA3 or OCA4 genes, by administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of the compound (2-[2-nitro-4-(trifluoromethyl)benzoyl]cyclohexane-1,3-dione), also known as NTBC for a sufficient period of time. The administration of NTBC is believed to increase the amount of pigmentation in the subject and alleviate certain symptoms caused by lack of pigmentation in the eye tissues. Also described are methods of use of NTBC for increasing the pigmentation of a subject for cosmetic purposes, by administering to the subject a therapeutically effective amount of NTBC.

The invention provides a face shield for sports activities. The face shield comprises a facial covering shield, a plurality of foam pads, a nose shield portion and a pair of detachable straps. The facial covering shield has a pair of eye openings. The pair of detachable straps around the cheek and the forehead are fully adjustable and provide a comfortable and secure fit for the user. The nose shield portion protects the user's nose from injuries. The plurality of foam pads includes a pair of forehead pads and a pair of cheek pads, and, the plurality of foam pads are removable and reusable and can be adjusted to desired position to create perfect fit for the user's face. The design of the face shield is more unique and fits on the top of the forehead and leaves plenty of space and protects the eye portion and reduces and eliminates vision problems.

The present invention discloses glasses with an integral type nose support. The main features are as follows: the front end of a beam of the central part of a frame is provided with a forwardly-protruded horizontal plate, the lower part of the horizontal plate is provided with a vertical frame, the front end of the vertical frame is not provided with a wallboard, left end, right end and rear end wallboards of the vertical frame are connected together to form a guide groove, and the guide groove is internally provided with the integral type nose support capable of moving up and down; the front part of the lower end of the integral type nose support is provided with a lower nose support, the front part of the lower nose support is provided with a nose-bridge-shaped groove which is backward lean inclined from the upper end to the lower end, and the nose-bridge-shaped groove gradually increases from front upper direction to rear lower direction; the groove surface of the nose-bridge-shaped groove is provided with cloth with soft nap, and the cloth with soft nap is firmly bonded with the groove surface of the nose-bridge-shaped groove by universal glue. When in wearing, the integral type nose support directly hangs and supports on a nose bridge, the frame may not slide down to hang on two side wings of a nose, and may not press skin of the two side wings of the nose to damage the skin, vision problems are solved, and at the same time, no wound is caused, and the glasses are beautiful and comfortable, and can improve demeanor and temperament.

The invention is suitable for the field of the communication technology, and provides a password input method and device based on a touch screen. The method comprises the following steps of: when a preset operation for triggering password input is detected, obtaining a touch operation input by a user through the touch screen; according to the touch operation, determining the display mode of a virtual keyword, wherein the display mode of the virtual keyword comprises an amplified display mode; and when the display mode is the amplified display mode, obtaining a preset password; and according to the preset password, determining contents displayed by the virtual keyword corresponding to the amplified display mode. By use of the method, the problem that password input speed and accuracy is lowered since unnecessary troubles are generated for old people or groups with vision problems to input passwords because data on a password input interface is overmuch and the positions of fixed keys are randomly regulated can be solved.

The invention is applicable to the technical field of display content processing, and provides an adjusting method for display content. The adjusting method for display content comprises the following steps: snapshotting human face pictures of a user using electronic equipment at preset time intervals; calculating the difference between percentages of human facial contour interior pixels accounting for human face pixels in two adjacent human face pictures; when the absolute value of the difference between pixel percentages is larger than a preset threshold value and no any input operation is received during interval preset time, building a focal length setting display area; receiving a command for dragging to-be-displayed content to the focal length setting display area; amplifying the to-be-displayed content which is dragged to the focal length setting display area. The method well solves the condition that an old man / woman with a vision problem has poor user experience with electronic products.
