Parents are generally concerned about children's vision problems, and it is best to intervene before this age!
It is often said that the formation of personality is "three years old and eighty", in fact, visual health follows the same principle. Human eyeball development is almost synchronized with the brain, the optic nerve and retina are not mature at birth, and the radius of corneal curvature develops to nearly adult level at the age of 3, and the vision is about 0.5-0.6, until the end of vision development around the age of 8. Therefore, before the age of 3 is a critical period in the development of your baby's vision. If the baby has eye problems, it should be found in time and treated early before the age of 3 to create a "bright" future for the baby, if it is not taken seriously, it may be delayed for life.
Vision Test "Classroom": How to tell if your baby's vision development is normal?
1. Light sensitivity test
Neonatal visual abnormalities are difficult to detect at an early stage, and parents can make preliminary judgments from the sensitivity of the baby's eyes to light and the ability to track light. 2 months of baby perception of light has been very sensitive, when the light will cause closed eyes, frowns, if the baby at this time on the light irradiation no response, will not blink, it indicates that there is a serious visual impairment; about 3 months of the baby will be in a small range of attention and follow the object; about 6 months will show interest in bright colors, at this time can hold bright toys, pictures in the baby's sphere of influence shake, if the baby's eyes can quickly and accurately follow the object, indicating that there is a good tracking ability.
2. Development status
Your baby's eye development is also one of the important indicators. Parents can check whether the position of the baby's eyes is symmetrical, whether the eyeball rotation is flexible, whether the size of the eyelid fissure is consistent, and whether there is any case of different eyeball sizes or ptosis. Among them, the pupil is the object of attention, if the child's pupil is white, it may be a sign of congenital cataracts; eye enlargement, pupil dilatation may be congenital glaucoma; if the pupil is yellow, be highly vigilant against retinoblastoma, which is an eye disease that threatens the life of young children. For premature babies, it is necessary to be vigilant for changes in the pupils from birth and beware of severe retinopathy.
3. Look at the object posture
Take care of the window of "horizon"
Promote the baby's eye development to do a good job of addition and subtraction!
"Plus": a balanced diet, supplement nutrition
For the baby's vision development to do "addition" is actually very simple, for the baby who is in the golden period of growth and development, the major organs of the body need to supplement enough nutrients in time to ensure health, and eye development is naturally no exception. For example, the main component of the cell - protein, the repair and renewal of the eye tissue needs to constantly supplement the high-quality protein; food containing vitamin C is also beneficial to the eye, vitamin C is one of the components of the lens of the eyeball; vitamin B1, B2 is one of the nutritional sources of the optic nerve, once the lack will lead to eye fatigue and keratitis. This requires that the baby's daily diet should pay attention to nutritional balance and avoid the phenomenon of picky eating. At the same time, vitamin A, the biggest contributor to the baby's "eye protection", is a key nutrient that must be supplemented additionally.
Vitamin A, also known as retinol or anti-dry eye factor, is closely related to your baby's visual development. Vitamin A not only participates in the synthesis of rhodopsin in the eyeball, helping to improve photosensitivity, but also maintains the integrity and function of eye epithelial cells (such as conjunctiva, cornea and other parts), and improves the anti-infection ability of the eye. If your baby doesn't get enough vitamin A, the epithelial cells of the lacrimal ducts will change, resulting in decreased tear secretion and dry eyes due to lack of tear lubrication. Once the conjunctiva and cornea appear dry and degenerate, it will cause discomfort such as dry eyes, visual fatigue, burning sensation, etc., and induce dry eye disease, conjunctivitis, keratitis and other diseases, threatening the healthy development of the baby's visual function. However, the content of vitamin A in the daily diet is very limited, which is a nutrient that infants and young children are more prone to lack, so parents must follow the doctor's advice to give the baby 1 vitamin AD drop every day (such as Yi Kexin), which not only promotes vision development, but also plays an important role in vitamin AD to enhance the baby's resistance, promote bone development, intellectual development and prevent iron deficiency anemia.
"Minus": Stay away from blue light and use your eyes reasonably
"Do subtraction" is actually very simple, for some things or habits that damage vision, we must categorically refuse, and help the baby develop good eye care habits from an early age. At present, "blue light pollution" can be said to be the biggest obstacle affecting the baby's vision level, do not let the child prematurely contact mobile phones, tablets, TVs, etc. When using the eyes, also pay attention to encourage the baby to sit upright, control the baby's eye time, whether it is watching TV or reading picture books, it is best to take a break or look at the distance after every 30 minutes to prevent eye muscle fatigue. In addition, adequate sleep and 1-2 hours of outdoor activities a day can also effectively inhibit the occurrence of vision problems.
