World Eyesight Day is celebrated on the second Thursday of October every year and is worldwide. When it comes to vision problems, parents are familiar with myopia, hyperopia, amblyopia, astigmatism and so on. It is not until the teenager that vision problems are emphasized, and many problems can only be detected early in order to avoid deterioration at a later stage. Baby vision development process Neonatal period: the baby’s ability to see things must be placed on the object from the baby’s eyes at a distance of about 20cm, has lasted until 3 ~ 4 months; 4 ~ 7 months: 4 months after the baby’s eyes have the ability to adjust the visual focal length, at this time you will find that the baby can look at things far away or out the window. 4 months, the baby’s range of vision increased by a few meters or more, will continue to increase, until 7 months, the baby’s eyesight can not be adjusted, the baby’s eyes will be adjusted, the baby’s eyes will be adjusted. At 4 months, your baby’s range of vision increases by more than a few meters and will continue to do so until 7 months, when his or her vision will be close to maturity; at 1 to 2 years old: your baby’s vision is developing rapidly; at 3 to 5 years old: your baby’s normal vision can reach the level of an adult; and at 10 years old: the visual system will be fully mature, and by this time, many early-onset vision problems may be less likely to be corrected. This is why it is recommended that babies’ eye diseases be diagnosed and treated early. The American Academy of Pediatrics recommends that babies receive eye screenings at the following four stages Neonatal period: pediatricians should check newborns for eye defects, cataracts or congenital glaucoma before they leave the hospital (currently, domestic hospitals screen babies for hearing as well as vision after birth); 6 months of age: check for consistency of eye movements (for head-eye coordination) and for all possible diseases; 3 ~5 years of age: it is recommended that vision screening by a pediatrician should be done every year at this stage; 6 years of age or older: vision screening every other year after 6 years of age. What phenomena does the baby show that the mom needs to be alert? If your baby has any of the following symptoms, your mother needs to consult your pediatrician: 1. Squinting hard to see clearly; 2. Complaining of headaches, dry tired eyes or blurred vision after finishing homework or reading; 3. Having trouble seeing things close up; 4. Having trouble seeing things far away; 5. Having to tilt your head a lot to see; 6. Constant tearing; 7. Rubbing your eyes a lot and consistently; 8. Seeing heavy shadows; 9, Itchy, burning sensation in the eyes; 10, problems seeing colorful things; Several common vision problems 1, myopia: usually due to the cross diameter of the eyeball is too long to focus on the image resulting in the inability to clearly see objects in the distance. The American Academy of Pediatrics, as well as the American Academy of Ophthalmology, agree that wearing glasses does not reduce vision either. Myopia has a genetic predisposition, especially in premature babies. 2. Hyperopia: This condition is caused by the inability to focus the image correctly due to the shortness of the eyeball. Most babies are born with hyperopia, which will gradually disappear as the baby grows older. 3, amblyopia: when one side of the baby’s eye can not see things clearly, will use the other eye to see, the discomfort of the eye will be relaxed and no longer see things, the discomfort of the eye is known as the “lazy eye”. This eye is called the “lazy eye.” Because of this “laziness,” the vision of this eye becomes weaker and weaker. This problem needs to be detected before the age of 3 so that it can be treated in time and normal vision can be re-established by the age of 6. If detected later (after 7 to 9 years of age), the uncomfortable eye may permanently lose the ability to see. What are the dangers of electronics? The American Academy of Pediatrics recommends that parents and child care providers prohibit television viewing for babies two years old and younger. 1, a long time staring at electronic products, although it does not cause permanent eye damage, but there may be blurred vision, fatigue, this time can be relieved by rest; 2, a large number of studies have shown that frequent television and obesity phenomenon is closely linked; 3, too much early exposure to things that are not suitable for the baby’s age; 4, electronic products not only have an impact on the baby’s eyesight, but also may jeopardize the baby’s various development, so Parents should be careful in the baby to see the problem of electronic products, of course, but also to set a good example for the baby! How to prevent vision problems? 1, regularly take the baby to do vision screening, strive to do early detection, early treatment, premature babies should pay particular attention to eye screening, according to the doctor’s requirements of the time to do; 2, eye moderation, pay attention to rest; 3, the world is very beautiful, take your baby out for a walk more often. A new study shows that for every additional hour a baby spends outdoors each week, their risk of myopia drops by about 2 percent.
