The invention provides sgRNA for knocking out zebra fish pde6a and application of the sgRNA in visual diseases. According to the sgRNA provided by the invention aiming at a specific position, pde6a of the zebra fish can be knocked out or knocked down in a targeted manner by utilizing a CRISPR / Cas9 system. After pde6a is successfully knocked out or knocked down, a zebra fish model with impaired visual functions and normal retina development is obtained, and the model also has morphological changes such as shorter body length, smaller eyes and shorter inter-ocular distance and also shows a trend of increasing the length of an ocular axis. The zebrafish model provides an experimental tool and a model basis for the research of visual function related diseases.

The application discloses a VRAR binocular 3D target positioning method based on deep learning, which comprises the following steps: collecting an eye chart video of a human eye tracking interest point Pc variation, analyzing the state when the eyes are stable, and analyzing the time required for a position change of the eye tracking interest point; a binocular 3D positioning model is constructed, including a feature extraction model based on a pupil-corneal reflection vector method, a 3D positioning model and a feature fusion module; each small eye chart change video and various features are taken as input parameters, and the three-dimensional coordinates of the interest point are taken as output parameters, which are input into a position recognition model for training and learning to obtain a trained position recognition model which is used in the practical stage; then, the position recognition model is saved and updated to a data set and used as a personal data set of a user to improve the adaptability of the personal model to the user.

The application provides sgRNA for knocking out pde6a of zebrafish and application thereof in visual diseases. By using the sgRNA for a specific position provided by the application, the pde6a of zebrafish can be targeted to be knocked out or knocked down by using a CRISPR / Cas9 system. After the pde6a is successfully knocked out or knocked down, a zebrafish model with impaired visual function but normal retinal development is obtained, and the model also has morphological changes such as shorter body length, smaller eyes and shorter interocular distance, and also shows a trend of increased axial length of the eye. The zebrafish model provides an experimental tool and a model basis for the research on diseases related to visual function.

A one-piece patient interface device for coupling an eye of a patient to an ophthalmic surgical laser system includes a tapered base having a rigid frustoconical housing for coupling to the laser system, and a flexible suction ring integrally joined to a lower end of the rigid housing for coupling to the eye of the patient. The suction ring has a circular skirt extending downwardly from a base portion, a septum extending from the base portion and disposed within the skirt, and a contact lens held by the septum to cover the central opening. When the skirt contacts a surface of the eye, the skirt, the septum, the contact lens, and the eye surface form a vacuum chamber where a vacuum may be applied to secure the patient interface device to the eye. The parameters of the suction ring are optimized to fit a wide range of eye sizes, including smaller eyes.

The invention discloses a fatigue monitoring method based on eye movement and blinking behaviors. The fatigue monitoring method comprises the following steps: step 1, carrying out eye image acquisition by adopting glasses type equipment; step 2, based on the collected eye image, performing eye movement tracking by introducing eye image quality enhancement and helmet slip compensation; 3, detecting eye scanning features based on the fixation point position obtained through eye movement tracking in the step 2, and representing the eye scanning features by adopting the eye scanning speed; step 4, detecting blink features of the user based on the eyelid ROI image obtained through quality enhancement in the step 2; and step 5, judging the fatigue state of the user based on the detection results of the step 3 and the step 4. According to the method, the problem that the monitoring accuracy is insufficient due to the fact that various blink characteristic values calculated by an existing eye movement monitoring mode are easily interfered by factors such as individual differences and environment illumination is solved, and the problem that the fatigue state of a user with natural small eyes is easily misreported is solved.

The utility model discloses an eyelash brush with a triangular iron brush rod, which comprises a blowing bottle, a cover, an inner plug, a brush rod and an inner cover, the inner cover is provided with an inner cavity, the brush rod is connected with the inner cavity of the inner cover, the inner cover is positioned in the cover, the inner plug is positioned on the inner side of the blowing bottle, the inner plug is provided with a hole-shaped structure, the brush rod penetrates through the hole-shaped structure and is positioned in the blowing bottle, and the brush rod comprises a connecting part and a brush rod main body. The brush rod body is of a triangular iron brush structure. The brush rod main body comprises a plurality of continuous spiral brush surfaces and a top end brush surface; a cutting surface is arranged on the side surface of the spiral brush surface; the multiple cutting faces are evenly distributed on the circumference of the spiral brush face. The number of the cutting faces is three. The eyelashes at small parts such as canthus, eye tails and the like can be easily touched through the tip design of the eyelash curler, the eyelash curler is particularly suitable for people with double inner parts, small eyes or shorter eyelashes, and missing coating is avoided; through multi-angle smearing of the triangular iron brush structure, the angle can be adjusted through different edge faces of the brush head, each eyelash is evenly wrapped, and the makeup efficiency is improved.

The invention discloses a canthus expanding and shaping device, and particularly relates to the field of medical cosmetology, the canthus expanding and shaping device comprises two rotating rods, the two rotating rods are both provided with grab handles, the rotating rods are provided with hollow axes, the two rotating rods are hinged through the same hollow axis, the two rotating rods are both fixedly provided with expanding seats, and the expanding seats are arranged on the two rotating rods. And the two expanding seats are far away from each other to expand the eyelids of the user. By arranging the rotating rod, the grab handles and the expanding bases, the expanding bases are close to the eyes, the two grab handles are expanded through fingers, and under the hinge action of the hollow axis, the two expanding bases are away from each other to expand the eye skin of a user, so that the effect of expanding the eye skin of the user is achieved, and the eye skin of the user can be expanded on the premise that an operation is not needed. The situation of the inner canthus of the small eye of a user is corrected, the inner canthus can be expanded to fix the inner canthus skin so as to achieve the effect of changing the size of the small eye, surgery is not needed, operation is easy, and use risks are avoided.
