Abstract: children especially need to pay attention to eye health. The time of continuous close eye use should not be too long. Every 40 minutes or so, you should overlook or close your eyes for 10 minutes; Usually to ensure adequate sleep, work and rest; Balanced diet, reasonable nutrition, etc. Special attention shall be paid to the rational use of eyes to avoid excessive use of eyes and adverse visual stimulation.
true myopia is irreversible. At present, there is no good method in medicine to completely inhibit the progress of juvenile myopia. It can only be corrected by some auxiliary instruments, such as frame glasses, corneal shaping glasses and so on.
corneal shaping lens is a kind of corneal shaping lens designed with special inverse geometry. Its inner surface is composed of multiple arc segments. The lens and tear layer are unevenly distributed, and the resulting hydrodynamic effect changes the geometric shape of the cornea. When sleeping, it is worn in the front of the cornea, gradually flattening the corneal curvature and shortening the ocular axis, so as to effectively prevent the development of myopia. The effect of visual acuity correction is very obvious, especially the control of the growth of myopia in adolescents is obviously better than other methods, Known as “sleep can control and correct myopia technology”.
doctors also stressed that although corneal shaping lens has many advantages, its fitting is a comprehensive and complex work and a medical behavior. You must go to a professional ophthalmic hospital and go through a series of strict ophthalmic examinations before fitting.
children’s myopia is deepening, which may be because these points are not done correctly.
I. predict the development process of children’s myopia.
everyone is hyperopia at birth, that is, the eye axis is short, and the imaging of external objects is focused behind the retina. With the growth of our age and physical development, the eye axis will also grow. Slowly, the light will focus on the retina, that is, facing the eye. However, for some reasons, the eye axis of some people is too long, and the light cannot focus on the retina, but in front of the retina, which is what we usually call myopia. The premature depletion of hyperopia reserve by
means that the eyeball develops too fast, that is, the length of the ocular axis at this time has been greater than the normal physiological value. Therefore, monitoring children’s axial development speed and hyperopia reserve consumption is an effective method to detect children’s myopia tendency and prevent myopia as soon as possible. Experts from
suggest that from the age of 3 to 6, a comprehensive optometric examination should be conducted once a year, and a refractive development file should be established. Regular ophthalmic examination should be conducted every year, so as to find out the changes of children’s eyes in advance, predict the future development trend, make targeted prevention and treatment, and help children’s eyes grow healthily.
2. Change unhealthy eye habits
we all know that too much mobile phone play, hiding in the quilt, reading, etc. will lead to myopia. Too much close eye use will lead to myopia because of ciliary muscle fatigue. When using the eyes closely, the ciliary muscle is in a tense state, which is equivalent to that we have been carrying a heavy object, resulting in excessive fatigue of the ciliary muscle and weakening of the regulation ability.
therefore, children especially need to pay attention to eye health. The time of continuous close eye use should not be too long. Every 40 minutes or so, you should overlook or close your eyes for 10 minutes; Usually to ensure adequate sleep, work and rest; Balanced diet, reasonable nutrition, etc. Special attention shall be paid to the rational use of eyes to avoid excessive use of eyes and adverse visual stimulation.
III. increasing outdoor exercise time
research shows that increasing outdoor activity time has a clear protective effect on the occurrence and development of juvenile myopia. Therefore, when parents are free, they must take their children outdoors. More outdoor activities are less likely to develop myopia. For children who want to prevent myopia, outdoor activities should be at least 2 hours a day, and 3 hours is better.
