Five features:
1, through the Optical imaging principle, a set of color images and a set of different spatial frequencies of the grating, checkerboard grid as a visual standard in front of the patient for regular periodic back and forth movement, so that the function of the eye regulation system (mainly ciliary muscle) to get full exercise in order to lift the spasm of the ciliary muscle muscle flesh, so that it gradually restore its own regulatory function.
Luminance of 100-180LUX. According to the principle and requirements of visual physiology, the retina of the human eye accepts the luminance of 100-180Lux as the most suitable, too bright and too dark can not be, too bright will burn the retina, too dark will cause visual fatigue. Hengtong YP-9 takes into account the quantitative issue of brightness.
Suitable motion rhythm for ciliary muscle: 1 time/20 seconds. The ciliary muscle needs to be exercised to restore its function. Exercise ciliary muscle should also be in line with the physiological characteristics of the ciliary muscle, the instrument in the visual standard back and forth speed must be set according to the physiological characteristics of the ciliary muscle, can not be too fast, too fast to keep up, too slow to achieve the purpose of exercise.
2, with a specific spectrum (500-600 wavelengths of yellow light) to stimulate visual cells.
The use of a specific spectrum of yellow flashing light points, so that the macular area photoreceptor cells get highly excited, increasing the quantum of incident light in the eye, in favor of the recovery of the functional depression of the photoreceptor cells.
3. High-intensity scintillation light increases the incident light quanta to improve the functional recovery of form deprivation amblyopia and wasting macular area.
4, the use of high-definition achromatic composite coated lens
Hengtong YP-9 used for the object of myopia and amblyopia of young people, in addition to the principle of optical imaging, in order to ensure the quality of the image, the light as far as possible through the lens, the use of high-definition achromatic composite coated lens, so that the system imaging range and clarity is greatly enhanced.
5, can be in the patient to see the most clear when the frame, clear imaging in the retina. Hengtong YP-9 has a grating, checkerboard picture (visual standard) by combining the newly assembled replacement frequency scintillation light source, which is conducive to improving the time characteristics and spatial characteristics.
Product Name: Hengtong YP-9 Third Generation
Product Category: Eye Care Instrument
Introduction: Hengtong YP-9 is suitable for the prevention and treatment of myopia, strabismus, refractive error and visual deprivation amblyopia in young people, and it is the necessary therapeutic instrument for myopia, refractive error amblyopia and amblyopia whose diagnosis is not clear.
They are the ones who blew it up, and personally I think that one is a piece of junk. This is the most recent information I have collected on the Internet, I hope to help you;
First of all: because the glasses are placed directly on the eyeballs, although there is a potion to wash, but there is always something that can not be washed clean, I had a few hundred dollars to buy a pair of to wear, but soon I threw it away, I strongly recommend not to wear contact lenses.
Surgery: the general age of eighteen years old, more than 1,000 degrees to do laser surgery is more appropriate, low degrees can also be done, but the principle of laser surgery is to cut the cornea thin, can be a person has the function of restoration, like wounds will heal themselves, the cornea will be regenerated after the thinning of the cornea, and the low degree of recovery sometimes luminosity will be back to the original level, or even deeper. Anyway, I and a lot of people around me do not dare to go, but there are people to go to the successful (that is my classmates) but do not know how to develop in the future can not be said, as if I heard people say that now has been prohibited to do the operation, and so on and so forth, anyway, I do not dare to go.
Secondly:
One, push the manipulation (eye exercises)
Take a sitting or supine can be, the two eyes naturally closed, and then in turn massage points around the eyes. The points should be taken accurately and gently, so that the local area feels sore and swollen.
1. Knead Tian Ying point: use both thumbs to gently knead and press the Tian Ying point (below the eyebrow, outside the upper corner of the eye socket).
2. Squeeze and press the eye point: use the thumb of one hand to gently rub and press the eye point (the root of the nose next to the inner canthus of the eyes) first downward, then upward to squeeze
3. Rub the Sibai point: use the forefinger to rub and press the Sibai point in the central part of the cheeks (the lower margin of the eye sockets is just below the center of the straight down a cross finger).
4. Press the solar plexus, wheel scraping orbital: use the thumb to press the solar plexus (the middle of the tip of the eyebrow and the outer corner of the eye backward at a cross finger), and then use the curved second section of the forefinger inner side of the light scraping orbital circle, from the inner upper - & gt; outer upper - & gt; outer lower - & gt; lower inner, so that the orbital periphery of the save bamboo fish waist, the Silk Bamboo empty, pupil liao, after the ball, Cheng Sue and other acupoints are massaged. For pseudomyopia, or to prevent the deepening of myopia is beneficial.
Two, ironing eyes method
This method is best to sit and do, the whole body relax, close your eyes, and then quickly rubbing each other's palms, so that the heat, while hot with both hands to cover both eyes, heat dispersion of the two hands after the violent take away, the two eyes are also at the same time with the strength of an open, so 3 to 5 times, can promote blood circulation in the eyes, enhance metabolism.
Three, eye breathing condensation method
Pick the air fresh place, or sitting or standing, the whole body relaxation, two eyes flat look ahead, Xu Xu will be full of gas inhalation, the eyes then widen, stop for a moment, and then will be slowly exhaled, the eyes also slowly closed, and continuously do 9 times.
Four, eye method
Select a quiet place, or sitting or standing, the whole body to relax, remove distractions, two eyes open, head and neck immobility, the only turn eyeballs. First, the eyes stare right below, slowly turn to the left, and then turn to stare right above, to the right, and finally back to stare right below, so that the first clockwise turn 9 circles. Then let the eyes turn from gazing below, to the right, to above, to the left, and back to below, so that, again, 9 turns counterclockwise. Do this 4 times total***. Each time you turn, your eyeballs should be as far as they can go. This eye-rotation method can exercise the eye muscles, improve nutrition, make the eyes flexible and free, bright.
Fifth, distant gaze:
Find a 10 meters away from the grass or green trees: green due to shorter wavelengths, imaging in the retina before, prompting the eye to relax the eye regulation, eye ciliary muscle relaxation, reduce eye fatigue. Don't squint or blink, remove distractions, concentrate and stare intently for 25 seconds to recognize the outline of grass or leaves. Next, hold the palm of your left hand slightly higher than 30 centimeters in front of your eyes, and look at the palm prints one by one, from head to tail, for about 5 seconds. After looking at the palm prints and then gaze at the distant grass or leaves for 25 seconds, and then look at the palm prints again. 10 minutes to repeat 20 times a day, three times a day to do, vision loss is very strong to increase the number of training.
Here there is also hot water to wash your eyes or use a hot pad to compress your eyes and temples.
