Nearsightedness or myopia
Does your child use to sit near the TV, the board in school or often stumble upon things in their environment? It may be a sign that the child is nearsighted.
Myopia, is a common misconception that causes objects to look blurred while objects close up are clear. This leads, for example, to young people finding it difficult to see the board in the classroom or that road signs become difficult to read for motorists.
It is unusual for children to be born with nearsightedness, but it is already possible to discover in the six or seven years whether the latter is likely to become nearsighted. It is more common for you as a six- or seven-year-old to be review and that it then grows away during adolescence. If the child is rather legal or near-sighted, the child will become increasingly near-sighted later when the eye grows. It is therefore important to test your child’s vision regularly to detect changes.
Myopia means that the eye is too long in relation to the breaking force. This causes you to look blurry in the far distance.
Your eyes focus on incoming light rays and send the image of what you see to your brain through the retina, a skin that sits at the back of the eye. In order to see an object clearly, the light rays must be collected at the same point on the retina. Myopia occurs when the eye is longer than normal or has a cornea that is too curved or too strong. Light rays from objects at a distance are then not focused on the retina, while light rays from objects close up, which require stronger refraction to focus on the retina, are still properly broken. In general, it is possible to see nearby objects clearly but objects at a distance become blurred.
There are several underlying reasons why some become nearsighted, although the exact cause is difficult to ensure. Just as with openness, genes play a big role. If one or both of your parents are nearsighted, you are also more likely to develop the same syntax.
The incidence of nearsightedness increases at a raging rate worldwide, especially among young people. In Europe, the proportion of nearsighted people has tripled over a 60-year period. What makes these figures so alarming is that the risk of developing certain eye diseases increases dramatically with increased myopia.
Did you know that the amount of time you spend outdoors as a child can be a preventive factor for myopia? Research shows that children who are outdoors often have a reduced risk of nearsightedness and that existing myopia can also be slowed down. Although there is no clear answer as to why this is the case, it is believed that it is much lighter outdoors than indoors. Sports and relaxation outdoors seem to be beneficial in reducing the risk of myopia.
Spending a lot of time reading, writing and using the mobile phone can also increase the risk of developing myopia. It is important to take regular breaks and to exchange intensive periods of reading and work with, for example, a walk outdoors. As our time is increasingly spent in front of a computer or mobile screen, even far down in the ages, the risk of myopia becomes unfortunately even more common in the future.
Without treatment, there is a risk that a child’s nearsightedness will greatly increase over time. It is therefore especially important that children do not wear glasses or lenses as nearsighted.
As you develop nearsightedness, you probably begin to notice that you cannot see distant objects as clearly as you used to. This may mean that you are struggling to read road signs or have to sit closer to the TV to see clearly. Activities that are done up close, like working in front of a computer screen or reading a book, are not affected and you will still be able to see nearby objects clearly.
Other signs that you may have developed nearsightedness include strained chewing, headache and eye strain. If you start to feel that your eyes are getting tired while exercising or driving, it may also be a sign of myopia that has not been corrected. Should you experience these symptoms even if you wear contact lenses or glasses, you may need a new prescription. If so, contact your optician.
Diopters are the device used to measure vision errors. The number indicates the strength required for the light to be broken correctly. When myopia is caused by too much breaking, glass and lenses need to have reduced strength to correct vision. Negative dioptrital therefore means nearsightedness, while positive speeches mean over-sight.
Low myopia: 0 to -2 diopters
Moderate nearsightedness: -2 to -6 diopters
High myopia: -6 up to -20 diopters
Glasses and contact lenses
Myopia can almost always be corrected with the right type of glasses or contact lenses. Glasses for those who have myopia are called minuscules and contact lenses are called minus lenses.
For children, the recommendation is to use the MiSight lens most so that it can slow down the development of myopia but also have a pair of glasses as a supplement. The MiSight lens is specially developed for children’s eyes and is soft day lenses. By avoiding the use of lenses at night, the risk of infections is greatly reduced. One-day lenses are more hygienic because they do not reuse the lens. The child opens a new lens every morning and then throws it in the evening. There are most clinical studies done on the Misight lens as a method of slowing the development of myopia.
