Eyeglasses are one of the most common types of glasses on a daily basis. Eyeglasses with a beautiful appearance can not only correct refraction, but also play an aesthetic role. A pair of eyeglasses usually consists of the main parts such as lenses, rims, nose pads, stilts and temples.
The materials are mainly metal, plastic or resin, natural materials, etc., and are divided into full-rim, half-rim, rimless glasses and other types.
A complete pair of eyeglasses usually consists of the main parts such as lenses, rims, nose pads, stumps, and temples, as well as foot covers, leaf screws, hinge screws, etc.
1. Lens: also known as the mirror core, it is the painting core after mounting, which is suitable for clamping in the frame, so it is called the mirror core. Its form can be horizontal or vertical, and it is a simple and convenient mounting type. Lenses can be divided into plastic lenses, special lenses, space lenses, and glass lenses according to different materials.
2. Lens ring (frame): The assembly position of the lens, with metal wire, nylon wire and screws, with grooves or drilled holes to fix the lens, it affects the cutting of the lens and the shape of the glasses.
3. Nose bridge: connect the left and right lens rings or directly connect with the lenses. The bridge of the nose is placed directly on the nose or supported by a leaflet.
4. Nose pad: including the leaf stem, the leaf box and the leaf support, the leaf support is in direct contact with the nose and plays the role of supporting and stabilizing the frame. Some cast-molded plastic frames can be made without leaf stalks and boxes, which are connected to the bezels.
5. Pile head: the connection between the lens ring and the temple, which is generally curved.
6. Temples: The hook is on the ears, which can be moved, connected with the pile head, and plays the role of fixing the lens ring.
7. Hinge: a joint connecting the pile head and the temple.
8. Locking block: tighten the screws and tighten the locking blocks on both sides of the lens ring opening, so as to fix the role of the lens.

First, understand what type of myopia you have. Myopia is divided into true myopia and pseudomyopia.
In the case of pseudomyopia, vision can be restored to a certain extent by taking proper rest and correct eye exercises, avoiding overuse of the eyes.
In the case of true myopia, proper rest and correct eye exercises can relieve eye fatigue and prevent myopia from progressing, but not restore vision. True myopia can be corrected with ultra-fast all-laser surgery, but not everyone can have laser surgery. The patient needs to be at least 18 years old, have no diseases and inflammation in the eye, and have sufficient corneal thickness, etc.
Before the operation, the regular eye hospital will give the patient a very detailed examination to ensure the effectiveness of the surgery and the safety of the patient.
If you don't want to have surgery, you can consider wearing orthokeratology lenses, which not only correct your vision, but also control the progression of myopia very well. Moreover, orthokeratology lenses are very convenient, you only need to wear them when you rest at night, and you can see clearly without glasses during work and study during the day.
Most optometry in optical stores is a simple computer refraction, which can detect the prescription, but the refraction is not accurate and comprehensive, and it is not sure whether it is true myopia. At the same time, wearing glasses with inaccurate prescription can harm the eyes and deepen myopia.
It is recommended that you go to the hospital for dilated refraction (the use of cycloplegic agents to refraction the patient while at rest) to determine whether it is true myopia or pseudomyopia, and then determine the plan to restore vision.
1. Pseudomyopia: due to frequent incorrect use of the eye, the ciliary muscle continues to contract and spasm, and the lens is also in a thickening state. In this way, the parallel light from the outside enters the eye, and after the atrial refraction of the thickened lens, the focus falls in front of the retina, and it is naturally not clear to see things in the distance. >>>More

First, go to a formal institution to do an eye examination for the child to see if the child's eyes are true myopia or pseudomyopia. If it is pseudomyopia, there is a possibility of recovery, and you can take your child outdoors to participate in activities or practice eye muscle training exercises such as playing table tennis. If it is true myopia, it means that the eye axis has grown, and there is no possibility of recovery, and only the progression of myopia can be controlled. >>>More
