Optical means are currently the most commonly used method in China to control the development of myopia in children and adolescents, and optical lenses such as orthokeratology lenses, defocused RGP, and defocused frame glasses are typical representatives. Among them, orthokeratology lenses and defocused RPG are hard corneal contact lenses, which have a better effect in controlling myopia. The wearing process is mostly done by children and adolescents themselves. Hard corneal contact lenses are small, with a diameter of less than 11mm. At present, the most common clinical and commonly used glasses wearing aid for children and adolescents is the glasses wearing stick, but the problem is that children have small hands and poor grip, and the glasses wearing stick lacks a fixing device, which is easy to hold unsteadily, causing the lens to move or slip off, resulting in damage to the expensive lens, and may even cause adverse complications such as corneal abrasions in the wearer, threatening eye health, affecting children's normal life and study, and causing unnecessary economic losses.

[0003] Therefore, an adsorption-type children's hard corneal contact lens wearing auxiliary rod is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 4 As shown, this embodiment provides an adsorption-type children's hard corneal contact lens wearing auxiliary rod, including: a rod body 1, a negative pressure suction cup 2 is fixedly connected to the bottom end of the rod body 1, and a lens holder 3 is fixedly connected to the top end of the rod body 1.

[0024] When in use, the outer surface of the hard corneal contact lens is placed on the lens holder 3 along the curvature of the lens holder 3, the negative pressure suction cup 2 is adsorbed on the fingertips of the child, the child pulls open the eyelids with one hand, and fixes the lens wearing auxiliary rod through the negative pressure suction cup 2 on the fingertips of the other hand, and then the hard corneal contact lens on the auxiliary rod is brought close to the eyeball, and the hard corneal contact lens can be worn. Through the adsorption effect of the negative pressure suction cup 2, the lens wearing auxiliary rod can be stably fixed, and only one finger is needed for fixing, freeing up other fingers. Compared with the simple rod body 1 that requires at least two fingers to clamp or multiple fingers to hold, it is more flexible and convenient, and the control is more precise.

[0025] Furthermore, the entire lens wearing auxiliary rod is made of silicone material, which is conducive to the adsorption of the suction cup and is not easy to damage the hard corneal contact lens.

[0026] According to a further optimized solution, the negative pressure suction cup 2 is a circular concave suction cup, and the top center of the negative pressure suction cup 2 is fixedly connected to the rod body 1.

[0027] The round concave suction cup fits the outer surface of the fingertip better and fixes it more firmly.

[0028] According to a further optimized solution, the negative pressure suction cup 2 is coaxial with the rod body 1 , and the plane where the highest point of the mirror holder 3 is located forms an angle of 75° with the axis of the rod body 1 .

[0029] The negative pressure suction cup 2 is coaxial with the rod body 1, and the lens holder 3 and the rod body 1 have an angle of 75°. This angle coordination conforms to the angle between the finger and the eyeball when wearing, conforms to ergonomics, and is more comfortable to wear.

[0030] According to the further optimized solution, the negative pressure suction cup 2 has a diameter of 9 mm and a thickness of 0.5-1 mm.
