Astigmatism is caused by the unequal light which refers to all kinds of meridians of diopter that can not focus the outward light entering in eyeball. Thus, our views will turn to be vague. In other worlds, astigmatism is the flaw of eyeball which makes the distance objects images reflected on the retina with the straight line instead of the distinct dot. How should we prevent our eyes from astigmatism?
Treat it as early as possible
The astigmatism can be divided into the sort of ametropia and it also can be classified as regular astigmatism and irregular astigmatism. All of them will bring about discomforts and vague vision as well as headache. At present, parts of students suffer from the headache due to the overburdened with their study. Their parents misread their source of their symptom. They take them to Pediatric Neurology or brain surgery for remedy, and check their children’s symptoms by CT and QMRI which take a large amount of money, but without any exceptions.
Finally, they will go to eye ophthalmology as the former exams can not check out any issues. A couple of children are well performed with their distance and near vision, but can not pass the mydriasis optometry if they suffer from astigmatism. If you correct astigmatism by the suitable eyeglasses at once, your vision will gradually improve and astigmatism symptom disappeared in a period of time. So it is quite necessary for taking an early treatment for astigmatism sufferers.
How to block children from the diseases of astigmatism?

Nowadays, vision problems including nearsightedness and farsightedness commonly occur in children. It is widely believed that these types of vision imperfection are caused by improper use of children’s eyes during their study and other entertainment activities such as watching TV. Since children’s eyes are immature, eyeglasses are the mostly suggested solution to correct their vision problems. One concern is that children’s eyeglasses have considerably changed in number and styles, causing a potential confusion in parents. There are some things that should be clear in the mind of parents who want to buy eyeglasses for their children.
A simple criterion is to follow the instructions or directions of the optician based on the prescription of the child. In general, there are two groups of children who need to wear corrective eyeglasses. One is required to wear glasses only when reading the black board in class, writing at home and the like. The other group is advised to have glasses on constantly. This classification is depends on the severity of vision problems.
It is widely known that a heavy prescription always requires a pair of thick lenses which is matched with the latter group aforementioned. In this case, small frames are preferred so as to maintain the accuracy of vision correction. Actually, lenses thickness decided by prescription has a direct impact on frame style. The final decision should be made by the optician.
Another significant aspect is lens type. Among the various lens materials in the market, polycarbonate is the best for children. This material is also widely used to make bulletproof glasses and windows. Polycarbonate is considered as the sturdiest material available for making eyeglass lenses. Children may frequently drop their eyeglasses during entertainment. Polycarbonate lenses are scratch resistant. They are naturally UV blocking. What’s more, glasses made of polycarbonate are much lighter than that are composed of regular plastic or glass.

The earlier the eye problem is found in children, the more likelihood the problem can be cured. So eye problems should be identified at an early age. Parent should pay attention to the children’s eyesight particularly from two terms, including posture and signs of emotional disturbance.
Posture has an importance influence on the general health and vision of a person. Poor posture results in malfunctioning of many parts of the body. If an employee walks with his head down to the office and sags dejectedly against the wall when waiting to be interviewed, he must be thought to be no initiative, no stamina and no confidence, and I think no employer will hire a person like that. Also, the bending posture will cut off blood and air circulation which is bad to your health, as well as eyes. Actually, it is particularly necessary to tell the children to have a good posture since they are young because it is much easier to correct the wrong posture at a young age. However, you should not just tell the child with querulous to stand up straight. You had better observe his posture and know what muscles the child is using wrong. If he slumps or if his spine is out of line and his head down and his chest caved in, you have to take him to the doctor for a check up so that the problem can be discovered and treated. Posture not only affects the opinion that people have on us but also the opinion that we have for ourselves, so try now to tell your children to walk with head erect, shoulders back instead of walking with head down and shoulders slumping.
Psychiatric studies reveal that most of the emotional disturbances originate since childhood and because bad vision is partly caused by mental disturbances, so it is very important to protect children from emotional shocks. It is of great significance for parents to keep the sense of security at home. A hysterical mother or an abusive father can lead to the emotional strain of a child thus bringing about defective vision when he reaches puberty. Though a child does not understand the situation whether his living condition is safe or not, he can deeply influenced by the surrounding environment. It is the same with the fact that though the child cannot express his feeling with the right words, he can completely have the feeling of fear or shock and it is difficult for him to get rid of that feeling because he have no one to share the feeling at all. As a parent, it is your duty to give a peaceful environment to your children and also care more about their feeling.
Children should not only be cared about with enough food. They require more love and care. Pay attention to their postures and emotional disturbance will make your children grow healthily and happily.
Vision problems about infants and children
Eye issues of preschoolers
Vision problems of children
preschool children can be fine-tuning the vision when they master the complex hand-eye coordination. They can ride bicycles in right direction they want to go while dealing with pedal and steer. For some old preschoolers, they also play more sophisticated sports. Though preschool children who have already developed their vision during infant and toddle years, they are vulnerable to vision problems if they don’t correct some bad habits.
You should make sure whether your children have the following refractive errors. Your kids may be used to sit too close to the TV and sometimes they just close one eye to watch. Some children prefer reading at close range, which can also lead to nearsightedness. Behaviors like squinting and tilting the head to see better are warning signs. Excessive tearing and light sensitivity are warning signs as well. Encountered any of these above situations, it is essential to schedule an appointment with your eye care practitioner.
Vision problems such as farsightedness, nearsightedness and astigmatism are very common in preschool children. Excessive farsightedness can lead to strabismus. For severe crossed eye, a surgery is needed. Some untreated strabismus may cause amblyopia and eventually blindness. Nearsightedness and astigmatism also require correction with glasses. They can both lead to blurry vision.
As children’s visual systems are flexible and elastic at the preschool stage, it is very necessary for children to take a complete eye exam before they enter school. Generally, children should receive an eye exam by the age of 6 months if they don’t have some vision problems or some refractive errors according to the American Optometric Association (AOA). If your kids require corrections for nearsightedness, farsightedness or strabismus, you’d better to arrange an exam every year. Annual prescription changes of eyeglasses or contact lenses are very common in children.
Another important aspect is that you should make sure if your children have received a comprehensive eye exam, not only screenings. Sometimes screenings are not administered by eye care practitioners and may not reflect your kids’ eye condition correctly.
After the eye exam of your kids, you also need to encourage them to wear eyeglasses in proper way. You should explain why they need to wear eyeglasses and give some specific example if necessary. When choosing frames, you should respect your kids’ choice. In addition to the better vision, you also need to pay attention to the comfort of frames. Since the result of eye exams may be influenced by physical condition, it is not wise to visit an eye doctor when your kid is tired or hungry.
In today’s world higher percentage of kids are getting disorders of eyesight, mostly nearsighted. Some of the kids get pseudomyopia which needs to be treated by doctors and they may recover to normal. While for some other kids the disorder of their eyesight become irreversible, then these kids need to buy eye wear to correct their sight.
Eye wear for kids range from eye wear with childhood marks or logos to some mature styles or a combination of both. When choosing eye wear for kids, one thing that should keep in mind is that we must let kids be an active participant to selecting the eye wear for them. This ensures that they will like to wear their eye wear. If kids do not like the eye wear, their frequent taking-off or eye wear from their heads will only worsen their eyesight.
On the frame materials, experts recommend parents to buy plastic eye wear instead of metal ones. In choosing the lenses, better quality anti-scratch lenses will be the first choice, as kids may use unsuitable cloth or paper to clean the lenses which will cause scratches and make the lenses blurry.
As kids are in the ages of fast growing, one pair of eye wear may become unfit in a short time. So a new pair of eye wear is necessary if the frame size does not fit again.
Another thing worth pointing is that parents need to carefully observe the reaction of kids after putting on a new eye wear, and be sensitively aware of any change of eyesight. If unfavorable thing occurs, consult and see a doctor for a new prescription, and get a new eye wear.
