Question 1: Is the "eye protection lamp" a "magic weapon" or a "placebo"?

Pointing to the online shopping App, search for "eye protection lamp", the emergence of the product will certainly let the parents pick the eye. The price of eye protection lamps on the market ranges from tens of dollars to thousands of dollars, a strange parameter, so people are dazzled.

Shen Yeyu introduced, when selecting eye protection lamps for children, one of the most important principles is that the relevant parameters should be in line with national standards.2018 implementation of the national standard GB/T9473-2017 "reading and writing homework desk lamp performance requirements" for reading and writing homework desk lamps, color rendering, color temperature, blue light hazards, stroboscopic flicker, illuminance, illuminance uniformity, and other indicators have clear requirements.

When parents choose eye protection lamps, they should try to choose eye protection lamps without strobe. Shen Yeyu explained that every flicker, the child's pupils will follow the contraction, dilation, invariably increase the burden on the eyes, the eyes will feel fatigue. Try to choose the color of the light is slightly yellowish in white. Good eye protection lamps simulate sunlight to form an artificial simulation of white light. Normal home use is generally an artificial light source, while the outdoors are continuous light will not cause an increase in myopia.

Question 2: Will the plastic lenses become inflamed and infected or thin when worn on the cornea?

Once myopia occurs, parents in order to prevent their children's myopia continues to progress or progress too fast, keratoplasty lenses have become the first choice of many parents, but at the same time, there are parents who wondered, plastic lenses to wear to the cornea, will there be inflammation and infection or thinning of the cornea?

Shen Yeyu explained that the chances of serious complications from wearing keratoplasty lenses in the clinic are very low. He explained that the corneal reshaping lens is reverse geometry "multi-arc" design, through the physical effect of the cornea central zone flattening, to achieve the effect of temporary reduction of myopia, to achieve the role of daytime with clear vision. At the same time, the second arc of the lens forms the peripheral retina's farsighted out-of-focus state, effectively slowing down the growth of the eye axis, to achieve the effect of slowing down the growth of myopia in young people. If your child's eyes are stinging and tearing, stop the medication in time and go to the hospital for treatment, and you'll be back on your feet in no time.

Question 3: Are low-concentration atropine eye drops safe?

Low-concentration atropine eye drops are 0.01% atropine eye drops, which is a kind of medicine that effectively slows down the development of myopia and is favored by many parents. Since there is no finished 0.01% atropine eye drops in the clinic, many parents choose to buy them overseas.

Shen Yeyu said, he does not advocate self-purchase and use of drugs, myopic children should be combined with his situation to use drugs carefully. The principle of low concentration of atropine eye drops is to act on the choroid under the eye, so that its vasodilatation, increase the thickness of the eye wall to slow down the development of myopia. Whether long-term use will cause other future ocular changes is still under observation. In the clinic, even when faced with a situation where use is necessary, doctors need to monitor the medication on a regular basis, not only to look at the development of myopia and the length of the eye axis, but also to look at changes in the accommodation function, to keep the side effects to a minimum.

Question 4: Is it necessary to check the eye axis every time my child has a vision test?

Usually, as a child's body develops, the eye axis grows. The length of a normal eye is about 18mm at birth, 22.8mm at 3 years old, and 23.5-24mm in adults. Myopic people's eye axes are usually larger than 24mm. The longer the eye axes are, the higher the myopia, so many parents like to stare at the eye axes when they have a vision checkup.

Shen Yeyu said, the eye axis of the big data standard value, can only be used as a reference, although there is a mean value, but its standard deviation is quite large, for each child, look at the eye axis alone, there is no meaning. To systematically observe the child's developmental status, do not focus on a particular indicator to judge, in general, adolescents and young people within 50 degrees per year increase in refractive status is a standard of stability.

When wearing framed glasses, you need to go through a standard medical optometry with glasses. Including the degree of myopia, astigmatism and axial, as well as the most easily overlooked by parents of the pupillary distance. The size of the pupillary distance determines whether the line of sight can pass through the center of the lens, and if the line of sight is shifted, a prismatic effect will result in strabismus. It is important to remember that the first optometric examination should always be done in a hospital with dilated pupils.

Scientific use of the eyes, remember the "three twenty" rule:

Although the students, office workers, the old comrades of the eyes of the hard work of the different ways, but in general, regardless of the adults and children, caring for the eyes, eye protection, basically all the common method. The. The "three twenty rule" is the eye protection law, that is, more than 20 minutes of close eye use, to look at distant objects more than 20 meters away for more than 20 seconds. This can effectively relieve the burden of eye regulation, thus avoiding the increase in myopia caused by prolonged over-regulation.

Shen Yeyu said that true myopia is irreversible. He suggested that myopic children or teenagers every three months to six months to carry out an optometry, the degree of change in the 25 to 50 degrees within the normal range, if the degree of change is required to dilate the pupil of the optometry, do not blindly dilate the pupil of the optometry.
