What is the principle of the control of myopia with the American Vision Membrane Shaping Lens? Want

Guidance: Orthokeratology lenses are orthokeratology lenses designed with a special inverse geometry, and their inner surface is composed of multiple arcs. The uneven distribution of the lens and the tear layer, the resulting hydrodynamic effect changes the geometry of the cornea, and is worn on the front of the cornea while sleeping, gradually flattening the curvature of the cornea and shortening the eye axis, thus effectively preventing the development of myopia, and is known as "the technology that can control and correct myopia by sleeping".

Orthokeratology lenses should be worn in a regular eye hospital and confirmed to be suitable after examination, otherwise, it will cause irreparable damage to the child's eyes. The Ophthalmology Diagnosis and Treatment Center is the ophthalmology center of the national public tertiary hospital, with a complete medical system, top-notch equipment, a complete optometry examination system, and clinically experienced doctors. In order to solve the problem of myopia in adolescents, it has spent a huge amount of money to introduce Christie and Dream David orthokeratology lenses from the United States, which has solved the myopia problem for many children, so that they do not need to wear glasses at all, which solves the troubles of parents.

There are more than 4,800-10,000 orthokeratology lenses**, depending on the patient's power, the brand selected and the material.

It is advisable to go to the hospital for effective counseling.

The American science and technology film shaping lens is a lens with a five- to six-arc inverse geometric design, which is powered by aerodynamic cutting technology, with extremely high finish and high material permeability. By wearing it at night while sleeping, the shape of the cornea is temporarily changed by the fluid dynamics of tears, etc., so that the curvature of the cornea is flattened, the refraction is changed, and the normal vision is achieved, and the progression of myopia is controlled.

Since 1998, the United States has a history of more than ten years in China, and it can be said that it is the forerunner of orthokeratology lenses in China, and many people wear them. Quality, Effect, Safety and Reliability! The level of trust is high!

Do you know how "orthokeratology lenses" can control myopia?

By wearing it for 8-10 hours when sleeping at night, the orthokeratology lens gradually flattens the curvature of the corneal ** area, which has the effect of defocus control, thereby effectively preventing the rapid development of myopia and temporarily improving the naked eye vision during the day, which is known as "the technology that can control and correct myopia while sleeping".

Orthokeratology is a new technology for non-surgical correction of myopia, which has good results in myopia correction and prescription control. It is designed according to the wearer's corneal geometry and refractive power, and is made of highly oxygen-permeable material for eye measurement, so it can maintain good naked eye vision as long as it is worn at night. It is the most effective for the correction of myopia in children and adolescents, and it is an advanced technology that effectively controls the progression of myopia for a long time.

Adolescents with myopia below 600 degrees can consider orthokeratology lens technology, which can control the development rate of myopia within 50% or even 30% of conventional glasses, and is especially effective in preventing the development of myopia in adolescents.

At the same time, orthokeratology only needs to be worn for 8-10 hours at night when sleeping, and the distance vision will be significantly improved during the day, which is very convenient to wear and use (Medigo orthokeratology lenses).

Well-known brands include Medigo Plastic Lenses, which are national chains.

In myopia, the eyeball is elongated, and orthokeratology lenses use external force to force the eyeball to temporarily press the eyeball to a normal level, so that the vision remains normal for a day.

Do you know how "orthokeratology lenses" can control myopia?

Through a series of examinations (corneal thickness, intraocular pressure, corneal curvature, corneal topography, etc.), corneal curvature greater than 46 can not be worn, in the case of suitable wearing, orthokeratology lenses are made by the curvature of the cornea is reduced, in short, the cornea is flattened, through overnight wearing, myopia will be reduced, and the next day is not to wear glasses.

Hello! Orthokeratology lens is a new type of juvenile myopia prevention and treatment glasses, it is through a physical shaping method, through a reasonable, programmed special design of a hard and resistant orthokeratology lens, at night, it is worn on the surface of the eye, and then the cornea is deformed according to the reasonable shape we set, through the change of corneal shape can make the original myopia, astigmatism some problems of adolescents be particularly and effectively corrected, The purpose of wearing glasses at night is to make the cornea of myopia become mildly myopic or become a cornea that is not myopia, during the day, teenagers due to the change in the shape of the cornea, so myopia is reduced or disappeared, if long-term use can make myopia be controlled to a certain extent, it can also play a role in prevention and myopia effect.

At present, this is a new technology for the prevention of myopia aggravation in the latest foreign research, especially for the control of myopia in adolescents.

2. What is the principle of orthokeratology lenses?

Generally speaking, soft things will deform with hard things, the cornea of our eyes is relatively soft, and the hardness of the corneal lens is higher than the hardness of the cornea, so in the process of wearing the glasses, the cornea will gradually change its shape through physical methods, this phenomenon is actually the principle of the invention of orthokeratology lenses by ophthalmic scientists.

Orthokeratology lens is a new type of juvenile myopia prevention and treatment glasses, which is a kind of rigid orthokeratology lens through a physical shaping method and a reasonable and programmed special design. At night, wear it on the surface of the eye, and then make the cornea deform according to the reasonable shape we set, through the change of the shape of the cornea, the original myopia, astigmatism and some problems of teenagers can be particularly and effectively corrected, so that the purpose of wearing glasses at night is to make the myopic cornea become mild myopia or become a cornea that is not myopia; During the day, adolescents due to the change in the shape of the cornea, so myopia is reduced or disappeared, if long-term use can make myopia to a certain extent, it can also play a role in prevention and myopia effect.

Hello, orthokeratology lens is a highly oxygen-permeable and awakening function of corneal correction contact lens, which can gently reshape the elastic cornea, so that the first part of the cornea tends to be flat, so as to change the refractive state of myopia, improve distance vision, and restore the purpose of clear state.

Physical principles, myopia defocus principle, eyelid pressure, surface tension.
