Do I need to lie down to sleep with OK glasses, and can I wear OK glasses during the day?

In order to ensure that the position of the lenses in the eyes is relatively correct and does not affect the corrected vision of the next day, it is recommended to lie down when sleeping. Specifically, you can go to Aier Eye Hospital, a professional ophthalmology department that can be fitted with orthokeratology lenses, to receive relevant examinations. [**Make an appointment with an ophthalmologist number source].

In general, there are some requirements for the sleeping position when starting to wear OK glasses. The principle of orthokeratology lens is to use the pressure of the eyelid to change the distribution of corneal epithelial cells through the force of the lens, cornea and tears, so as to shape the cornea, achieve a function similar to a concave lens, and correct vision.

Therefore, at night when children wear OK glasses, they should not sleep with their eyes pressed on the pillow, nor should they wear an eye patch or hood because their eyelids are pressed. This pressure is transmitted to the OK lens, which may cause the OK lens to deviate and affect the effect of the corneal plasty. So put on OK glasses for the first time and sleep on your back as much as possible.

As long as you wear it for a day or two, its shape is basically stable. In the back, if the child sleeps dishonestly, turning his head and feet while sleeping, or sleeping on his side, the impact will not be great.

If you want to know more about it, we recommend consulting Aier Eye Hospital. Aier Ophthalmology has established leading overseas ophthalmology institutions such as Asia Medical in Hong Kong, Mingwang Eye Center in the United States, and Europe. The internationalization of the company is conducive to the company's deep integration of international advanced medical service concepts, as well as the most cutting-edge technology system, whether it is a high-end service model, or advanced medical technology and management experience, can be grafted, the company to better develop domestic high-end medical services to promote the company, build a world-class scientific research, talent, technological innovation platform, global resource integration advantages further revealed.

According to Shijiazhuang Aier Eye Hospital, the principle of orthokeratology lens is to use the pressure of the eyelid to change the distribution of corneal epithelial cells through the force of the lens and the cornea and tears, so that the cornea can be reshaped and vision corrected.

<> wear glasses on the first night, try to lie down and sleep.

The pressure of the eyelids is very important, so it is OK to wear it at first, and there are requirements for sleeping position.

On the first night of wearing OK glasses, children should not sleep with their eyes pressed against the pillow, nor should they wear eye patches or sleep with their heads covered, because this will put pressure on the eyelids. This pressure is transmitted to the lenses, which can deviate and affect the effectiveness of orthokeratology.

Therefore, the first time you wear OK glasses, you should sleep as flat as possible. As long as you wear it for a day or two, the shape is basically stable. Later, if the child does not sleep honestly, the head and feet are reversed when he falls asleep, or he sleeps on his stomach and sleeps on his side, the impact will not be too great.

Adhere to good habits of healthy eye use.

In addition, children who have been fitted with OK glasses still have to follow the principle of combining movement and static, alternating near and far vision during the day

1. Two hours of outdoor activities every day;

2. Do not contact electronic products such as mobile phones, tablets, and learning machines early;

3. Avoid lying on your side to read, reading for a long time in weak or strong light, and achieve the correct posture of "one inch, one foot and one fist";

4. Use your eyes at close range for 30 minutes, stop and look into the distance and rest for 3 to 5 minutes;

5. Pay attention to balanced nutrition and eat less sweets and beverages.

Otherwise, the degree will still rise slowly.

It doesn't matter what position you sleep in while wearing the OK glass, as long as you can ensure that the OK mirror does not fall off.

Hello, it is better to lie flat, the effect will be better. Hope.

Sleeping on your stomach will be unevenly stressed, which will affect your vision the next day.

Orthokeratology lenses.

Spectacle lenses made of breathable rigid contact lens material, commonly known as RGP material, RGP is the abbreviation of Rigid Gas Permeable, that is, "breathable rigid material". It is developed on the basis of PMMA, a hard material that is not breathable. The "OK mirror" that is often seen in the market.

In fact, it is orthokeratology lenses.

Devise. Orthokeratology lenses are a special type of RGP lens. Ordinary RGP lenses are used to correct vision.

Shaped lenses, on the other hand, are used in "orthopedics", i.e., to improve vision by changing the shape of the cornea.

The inner surface of the "corrective" RGP lens is parallel to the surface of the cornea, and the luminosity of the lens is adjusted by changing the outer surface of the lens. The opposite is true for "orthopedic" shaped lenses. Its outer surface is relatively simple, and its inner surface is relatively complex.

The inner surface of the lens is no longer parallel or anastomosed with the cornea, but creates some gaps between the cornea of the lens, using the action of tears to achieve an "orthopedic" effect.

The correct way to wear OK glasses is to wear them at night, the wearing time can not be too long, and you can basically take off the glasses during the day after wearing them at night, if the eyesight is still not good during the day, it is recommended to replace the lenses or replace them with frame lenses. If you need glasses, it is recommended to go to Beijing Meier Eye Hospital. Click to test if I am suitable for myopia surgery.

OK lenses can be worn during the day, OK lenses are also known as orthokeratology lenses, using breathable rigid contact lens material, that is, spectacle lenses commonly known as RGP materials, RGP is the abbreviation of English Rigid Gas Permeable, that is, "breathable hard material". It is developed on the basis of PMMA, a hard material that is not breathable. The "OK lenses" that are often seen on the market are actually orthokeratology lenses.

Orthokeratology lenses are easy to use. Just wear it at night while you sleep and your vision will return to normal the next day. Patients with myopia within 600-800 degrees can quickly achieve above visual acuity within 1-2 weeks.

1. Why do you choose to wear OK glasses at night? Because the amount of tear secretion in the cornea increases during sleep at night, and the function of corneal epithelial cells is affected, we need to keep the lenses as clean and dry as possible when using them during the day and avoid using them for long periods of time.

2. Why do you choose to wear OK glasses at night This is because during the day we don't get enough rest, and because of the biological clock, we are more likely to fall asleep, covering the ridge but when we carefully convert the light into strong light, our eyes will become very tired, so during the day we should pay attention to adjusting our sleep time.
