Must read, parents, please put away this knowledge of children's vision
Bright eyes are the guarantee of a child's bright future. Many novice parents are happy when their children come, and they don't think of taking care of their children's eyes. Then please put away this knowledge of children's vision and always pay attention to children's vision health.
The state of vision development in infants and young children
At birth, babies and toddlers have just begun to develop their eyesight and can only know the swing of their hands in front of them.
At 3 months, he can see near objects and move his eyes freely. At 4 months, they begin to distinguish colors, adjust their vision in both eyes, and have a visual acuity of 0 at 6 months04-0.06。
When a child is 1 year old, visual acuity is 02-0.At 4,2 years of age, visual acuity can reach 05-0.6. By the age of 3, the visual acuity can reach 1About 60-70% of people above 0 reach 183% of those above 0.
From the age of 3 to 5 years old, the period is the fastest stage of infant vision development, and the visual development of children at the age of 6 is roughly the highest level.
In the infancy and early childhood of a child, the home light environment is very important
At present, most of the lighting sources used in our rooms are generally LED lights, and the white light emitted by the mainstream LED lights on the market is basically composed of blue light emitted by blue light chips, which is synthesized with yellow light after excitation of YAG yellow phosphor. In particular, short waves of blue light with wavelengths between 400nm and 450nm can penetrate the eye and have the potential to cause damage to the eye. This is also the reason why sometimes we inadvertently look directly at the lights in our homes, and our eyes will be blurred for a short time. In addition, it is true that children nowadays have a hard time of 2 hours of effective outdoor activity time every day for various reasons, and the opportunity for the eyes to absorb the beneficial spectrum is greatly reduced. In other words, when children are at home, harmful light stimulation + insufficient beneficial light is also one of the main factors that cause children's myopia, so the transformation of the home light environment is particularly important.
On the basis of optogenetics, nutrigenomics, etc., targeted photons have developed a series of eye protection lamps using biophoton technology. On the basis of the configuration of the visual light (VL) range spectrum of diffuse sunlight, this series of products optimizes the configuration of the missing or missing spectral frequency bands of artificial light sources according to the spectral differences exposed to regular artificial environmental light sources and the composition ratio of 9 light-dependent opsins of chromosomes in human vision-related cells, so as to supplement the beneficial spectrum for the eyes, and realize the accurate and rapid adjustment and improvement of ocular shape, light and color vision. In addition, the relevant lamps and lanterns simulate the color temperature of sunlight from 8 o'clock to 10 o'clock in the morning, and the light is soft and has no flicker, which has a positive impact on the prevention and control of children's myopia, and is very suitable for the transformation of the family light environment.
