An intelligent intraocular and extraocular muscle sensitivity exercise training instrument which is disposed with an ocular head (1) consisting of a front shell (11), a middle shell (12) and a back shell (13), and a control device (2) electrically connected to the ocular head (1), as well as an intraocular muscle exercise bar (3) electrically connected to the control device (2). The beneficial effects are as below: in addition to supplementing the field of portable intraocular and extraocular muscle training instruments, it is also convenient for students to put it in their school bags for use at any time thanks to its intelligent operations and foldable structure, it overcomes the shortcomings of the above-mentioned pure extraocular and intraocular muscle sensitivity training instruments. Therefore, it is bound to have a profound effect on myopia control, dyslexia remediation, eye healthcare, and memory improvement among teenagers.

An electrical skin treating appliance has an elongate hollow polymeric housing with front and rear portions. The front portion contains a reservoir for receiving and containing water. The rear portion has one or more controls. The housing contains an ultrasonic mist generator for converting the water into a fine mist and dispersing the mist from the housing. A sonically-vibratory spatula extends from the housing at a junction of the front and rear portions and is adapted to scrape the outermost surface of a user's skin. The housing contains an oscillation generator for selectively causing ultrasonic vibration of the spatula, and the one or more controls are adapted for selectively energizing, only one at a time, the mist generator and the oscillation generator.

The present disclosure provides improved methods and apparatus for evaluation of an individual's cognitive performance in a fast-paced, visually dynamic environment. The apparatus may comprise a display configured to present a plurality of stimuli to the subject, and a processor coupled to the display, the processor comprising instructions to determine a subject's visual perceptual skills, memory and learning skills, and response command and control skills. The methods and apparatus described herein can evaluate key cognitive processes that underlie split-second decision-making in visually dynamic environments. The results can provide comparison of cognitive skills across individuals performing in a specific environment, as well as evaluations of more targeted sets of cognitive processes for specific positions in an environment that might require unique sets of skills.

Disclosed herein is an optical device for restoring eyesight, which includes a first tube configured such that a first convex lens having a first focal length is installed to an inner peripheral surface of a fore-end thereof, a second tube inserted into the first tube so as to move forward and backward within the first tube while a first concave lens having a second focal length and a second concave lens having a third focal length are installed to an inner peripheral surface of a fore-end thereof, a third tube configured such that a third concave lens having a fourth focal length and a fourth concave lens having a fifth focal length are installed to an inner peripheral surface of a fore-end thereof, a fixing unit for fixing the second tube to the third tube, and a fourth tube fixed to the fixing unit to cover the second tube.

A method and system for treating a desired volume of tissue using HIFU or other energy modality includes ablating a pattern of elemental treatment volumes each having a volume that is greater than that of the focal zone of the HIFU transducer but smaller than the overall volume of the desired treatment volume. In at least one embodiment, the elemental treatment volumes are arranged to form a shell which partially or wholly encapsulates the desired volume of tissue, which then necroses in situ. The elemental treatment volumes are created by distributing HIFU energy in multiple doses with repeated passes of the focal zone of the HIFU transducer in a trajectory over or along a perimeter of each elemental treatment volume.

In a method of strengthening pathological muscles, the patient is subjected to a therapeutic strengthening exercise for strengthening a target muscle. The method begins at the start of the strengthening exercise in response to exacerbation of symptoms exhibited by patient. The symptoms exhibited by the patient during the strengthening exercise are minimized by a series of steps including adjusting an intensity of the strengthening exercise, limiting a range of motion of the strengthening exercise, dividing evenly a prescribed number of sets and repetitions corresponding to the strengthening exercise, dividing unevenly the prescribed number of sets and repetitions corresponding to the strengthening exercise, varying a speed at which the patient is subjected to the strengthening exercise, modifying a position of the patient for the strengthening exercise, matching a mode of the strengthening exercise to the modified patient's position, and switching between primary, secondary and tertiary actions of the patient's target muscle.

An eye massager includes an eyeshade and a head band connected with the eyeshade. The eyeshade is provided with two massage boards, and the two massage boards are arranged symmetrically and move synchronously. The eyeshade includes an eyeshade casing, the two massage boards are located on an outer wall of an inner side of the eyeshade casing, and the eyeshade casing is provided therein with a driving assembly configured to drive the two massage boards.
