How do myopia control glasses work?

Control glasses are made of control lenses, but this recent method is still little known to the French. For Dr Stéphanie Zwillinger’s COP9 team, it is important to spread the word and raise awareness in as many people as possible!

Discover in this article this way to slow down your child’s progressive myopia.

Presentation of how

control glasses work

 

Control glasses help slow down progressive myopia. They are made up of control lenses. They are prescribed by the pediatric ophthalmologist to myopic children, from 4-5 years old. These glasses are particularly recommended for young people with progressive myopia: they should be worn from the first observation of the beginning of the visual disorder, and kept as long as the eye care professional notices progression.

 

Classic glasses are based on the principle of light refraction. When light enters the eye, it must pass through several optical structures to form a sharp image on the retina, which is the light-sensitive surface at the back of the eye.

 

Myopia control glasses will act at the same time on the rays of central vision and on peripheral vision which will converge in front of the retina.

The progression of myopia is then slowed and the eye can no longer lengthen.

How do

control glasses work?

As a reminder, the main optical structures of the eye are the cornea, the lens and the vitreous humor.

 

Control glasses work by compensating for abnormal curvatures of the cornea or adding additional focusing power to strengthen accommodation of the lens. They are made up of corrective lenses that can be prescribed to children with severe myopia (greater than -6 diopters).

 

It is recommended to wear the control glasses for at least 12 hours a day, every day, in order to obtain optimal results in reducing myopia. If the use of control lenses is irregular, the results will be limited.

Control glasses are to be worn until early adulthood: when your ophthalmologist notices that the growth of your eye has stabilized, you can then move on to classic corrective glasses, contact lenses, or talk about refractive surgery, depending on your preferences. needs and medical profile.

Who can prescribe control glasses?

The ophthalmologist, such as Dr. Stéphanie Zwillinger, can prescribe control lenses, manufactured according to the prescription issued. The latter is based on measurements of the correction power necessary to correct the specific visual defect of each individual, expressed in diopters. Diopters determine the amount of correction needed to achieve clear vision.

For control glasses, changing lenses is generally prescribed when the ophthalmologist observes that his young patient is losing 0.5 diopters, or more, in at least one eye. It is therefore possible that only one control lens is prescribed.

Thanks to control glasses, a reduction in the frequency of changing lenses, and therefore new prescriptions, is also observed, thanks to the brake effect.

What are the

benefits of control glasses?

 

By wearing control glasses, young people with progressive myopia can benefit from optical correction which allows them to see clearly and sharply at different distances.

 

This improves their visual acuity, reduces eye fatigue and relieves headaches associated with blurred vision.

 

In addition, children adapt quickly to wearing control glasses and do not have any side effects. This type of control lens is similar to classic lenses, just as thin and smooth. The aesthetic aspect is not a problem!

 

It is important to emphasize that control glasses do not cure myopia, but can significantly slow down its progression.

 

Once an adult, if the myopic patient wants an alternative to glasses, it will be easier to resort to surgical treatments such as laser refractive surgery, which modifies the shape of the cornea to correct certain visual defects.

To conclude

 

Control glasses are optical devices that correct visual defects by modifying the trajectory of light rays in order to form a clear image on the retina. They are made of control lenses which will prevent, as much as possible, the young patient’s eye from stretching out.

 

These glasses offer an effective solution to obtain good vision and improve the quality of life and long-term vision of people suffering from visual disorders.
