A multi-effect eye beautifying method and intelligent introduction system

This invention relates to the field of cosmetic technology, disclosing a multi-effect mesotherapy method and intelligent infusion system for the eyes, addressing the shortcomings of traditional eye cosmetic procedures, such as short-lived effects, low safety, and limited improvement. The system includes an intelligent infusion device, infusion products, repair products, and post-operative tools. The infusion device precisely controls the operating depth to 0.25mm, working along a specific operating path. The method stimulates collagen regeneration in the eye area through cleaning and disinfection, layered infusion, product repair, ice compresses for soothing, and post-operative monitoring. It eliminates the need for Botox or surgery, simultaneously improving issues such as upper eyelid laxity, crow's feet, eye bags, and dark circles. The effects are natural, long-lasting, and highly safe, making it suitable for promotion in non-medical cosmetic settings.

A method for quantitatively evaluating the severity of dark circles

PendingCN122271957Areduce subjective errorAccurate typingObjective assessmentDark circles under the eyes
This invention discloses a method for quantitatively assessing the severity of dark circles under the eyes, belonging to the field of objective evaluation technology in cosmetic dermatology. The method divides the eye into the upper and lower eyelids, each assigned a 50% weight. Each area is scored in three dimensions: area (A), color (D), and structure (S). A weighted total score for each eye and a combined total score for both eyes are calculated. Based on the total score, the severity is classified as mild, moderate, severe, and extremely severe. Furthermore, the percentage of each indicator is used to classify the condition as pigmentary, structural, and mixed types. This invention provides an objective, standardized, and repeatable assessment. The combination of multi-dimensional indicators improves the accuracy of the classification. It can be used for preoperative diagnosis and postoperative efficacy comparison, and is compatible with automated assessment in medical aesthetic systems, solving the technical problem of the lack of unified standards in traditional subjective assessments.

A flexible eye movement perception and tracking device and an eye movement signal processing method thereof

A flexible eye-tracking and sensing device includes a flexible nano-silver film sensor. The flexible nano-film sensor is attached to the upper eyelid and connected in series with a power supply and a voltage divider resistor to form a circuit. A sound card is connected in parallel with the flexible nano-film sensor, and the sound card is electrically connected to a computer via wires. Using the above device for eye-tracking signal acquisition, preprocessing, and recognition, real-time eye-controlled human-computer interaction is realized. Experimental verification shows that the flexible eye-tracking and sensing device can not only realize eye-tracking control of software such as virtual games and virtual keyboards, but can also be used in combination with hardware facilities such as robotic arms, so that eye-tracking control is no longer limited to virtual scenes, but can also realize the control of real-world objects.

Wakefulness estimation device and wakefulness estimation method

The present invention comprises: a face image acquisition unit (102) that acquires a face image of a subject; an upper eyelid opening degree calculation unit (103) that calculates an opening degree of an upper eyelid of the subject on the basis of the face image of the subject; an upper-lower eyelid distance parameter calculation unit (104) that, when the opening degree of the upper eyelid of the subject is smaller than a first opening degree threshold value, calculates a parameter relating to the distance between the upper and lower eyelids of the subject on the basis of the face image of the subject; an eye closure transition parameter calculation unit (105) that calculates, when the opening degree of the upper eyelid of the subject is smaller than the first opening degree threshold value, a parameter relating to eye closure transition from a state in which the opening degree of the upper eyelid of the subject is greater than a second opening degree threshold value to a state in which the opening degree of the upper eyelid of the subject is smaller than the first opening degree threshold value; a downward vision determination unit (106) that determines whether or not the subject is in a downward vision state on the basis of the parameter relating to the distance between the upper and lower eyelids of the subject and the parameter relating to the eye closure transition of the subject; and a wakefulness estimation unit (107) that estimates wakefulness of the subject on the basis of the opening degree of the upper eyelid of the subject and the result of determination by the downward vision determination unit (106).

A meibomian gland model

ActiveCN224318096UEducational modelsMeibomian glandAnatomy
This utility model discloses a meibomian gland model, including a support assembly, an adsorption element at the bottom, and a detachable demonstration assembly at the top. The support assembly is height-adjustable, allowing it to move up and down. The demonstration assembly includes an eyeball demonstration element, which is partially covered by an eyelid edge demonstration element. Several gland demonstration elements are located on the eyelid edge demonstration element. The upper and lower eyelid demonstration elements are combined to form an openable shell, enclosing the eyeball demonstration element, eyelid edge demonstration element, and gland demonstration element. The upper, lower, and upper eyelid demonstration elements are made of elastic material. The lower eyelid demonstration element forms several channels, within which extrusion demonstration elements are retractable. Pressing the lower eyelid demonstration element causes the extrusion demonstration elements to extend out of the channels. This utility model facilitates the disassembly and display of the internal meibomian gland structure, which is beneficial for teaching, observation, and research.

Cosmetic contact lens, and contact lens

PCT designated stageWO2026137638A1OptometryContact lens
Disclosed in the present invention are a cosmetic contact lens, and a contact lens. The contact lens has a spherical front surface, and a spherical rear surface configured to be worn on the eye, and the contact lens comprises an arc-shaped counterweight section, a gradient balance section, and a conventional section. The arc-shaped counterweight section is located on a lower half of the contact lens and is configured along the outer contour of the contact lens. The gradient balance section is connected between the arc-shaped counterweight section and the conventional section, and the thickness of the gradient balance section gradually decreases in the direction from the arc-shaped counterweight section to the conventional section. The contact lens has an optical portion through which the eye can see. In a top view of the contact lens, the gradient balance section overlaps with 5%-45% of the area of the optical portion. Therefore, the arc-shaped counterweight section facilitates rotation towards the lower eyelid, and the two correction ends can be pushed by the blinking of the upper eyelid, so as to be more accurately maintained in a preset position.
