A light source is situated on a headgear device and placed to direct light toward the pupil of the eye at an intensity that causes the iris to constrict, resulting in a smaller pupil. This prevents the light scattering due to ophthalmic surgery or eye injury from entering the eye, thereby reducing or eliminating visual aberrations.

Meanwhile, the design of the adjusting sheet can enable medical personnel toquickly distinguish the upper position and the lower position and to improve the nursing working efficiency of the medical personnel.

Isolated, mammalian, mature bone marrow-derived, lineage-negative hematopoietic stem cell populations (Lin-HSCs) containing endothelial progenitor cells (EPCs) are capable of repairing retinal vascular and neural networks in the eye. Preferably, at least about 20% of the cells in the isolated Lin-HSCs express the cell surface antigen CD31. The isolated Lin-HSC population has utility for the treatment of ocular vascular diseases. In a preferred embodiment, the Lin-HSC population is obtained by: extracting the bone marrow of an adult mammal, isolating multiple monocytes from the bone marrow, using biotin-conjugated lineage populations directed against one or more lineage surface antigens These monocytes were labeled with antibodies; monocytes positive for lineage surface antigens were removed from various monocytes, and then the Lin-HSCs population containing EPCs were recovered for isolation. Also provided are isolated Lin-HSCs transfected with a therapeutically useful gene for gene delivery into the eye in cell-based gene therapy. Also described are methods of making the isolated stem cell populations of the invention, and methods of treating eye diseases and eye injuries.

A biosensor for the detection of an analyte such as ascorbic acid is provided. Also provided is a device comprising the biosensor. In addition, methods of detecting analytes such as ascorbic acid in a sample, and methods of a point-of-care diagnosis of eye disease and eye injury are provided.

The invention provides an eye protection display method based on an intelligent terminal and the intelligent terminal. According to the eye protection display method, different eye protection modes can be configured according to different scene modes of different application programs; by monitoring the running time of the scene mode, when the running time of the scene mode meets the set duration,the eye protection mode is started autonomously, and the problems of eye fatigue and eye injuries caused by the fact that a user faces improper display hues for a long time are avoided.

The invention relates to an ophthalmic disease nursing device and belongs to the technical field of medical equipment. The ophthalmic disease nursing device comprises a nursing device body and a power supply box, a power interface is formed in the right side of the nursing device body, a heating pad is arranged on the ophthalmic nursing device body, a main control console is arranged on the front upper side of the heating pad, eyeshade supporting rods are arranged on the right side of the main control console, an eyeshade supporting rod inclined strut is arranged on the left side of each eyeshade supporting rod, eyeshade rotating shafts are arranged on the upper sides of the eyeshade supporting rods, eyeshade connectors are arranged on the eyeshade rotating shafts, eyeshade connecting rods are arranged on the eyeshade connectors, eyeshade fixing sheets are arranged on the eyeshade connecting rods, and an eyeshade is arranged on the eyeshade fixing sheets. The ophthalmic disease nursing device is complete in function and convenient to use. When ophthalmic disease nursing is performed, operation is flexible, use convenience is achieved, eye injury recovery can be effectively promoted, eye injury early warning can be given out in time, and the burden on medical staff is relieved.

The invention discloses an intelligent mobile terminal, an eye protection method for the intelligent mobile terminal, and an apparatus with a storage function. The eye protection method comprises thesteps of obtaining real-time image information by the intelligent mobile terminal; performing data conversion on the image information to obtain facial pixel information; through the facial pixel information, judging whether a distance between a face and the intelligent mobile terminal is smaller than a preset distance or not; and if the distance between the face and the intelligent mobile terminal is smaller than the preset distance, starting an alarming function. Through a specific algorithm, the distance between the face and the intelligent mobile terminal can be judged more accurately, sothat the problem of eye injury caused by short-distance use of equipment by users is solved and the user experience is improved.

A spectacle frame and a manufacturing method thereof. The spectacle frame comprises a frame, a bridge of the nose, nose pads comprising support leaves and support arms, and a pin head. The support leaves are made of a soft material, in a closed hollow shape, or has smooth edges. The spectacle frame can effectively reduce eye injury to a user during working or exercise.

Embodiments of the invention provide apparatuses, methods, and systems for projecting images into a projection zone, while having the capability to detect the presence and movement of objects in the projection zone and to interact with those objects, according to programmed interactions. One of the programmed interactions may be to detect objects in the projection zone and avoid projecting light onto them. The capability to detect and avoid objects in the projection zone may allow for the use of high intensity light images including laser light images around people and animals without the risk of eye injury. Another programmed interaction may be to project an illuminated image around people and objects in the projection zone to emphasize their presence and movement.
