What is myopia and how to avoid it?
Myopia is a visual disorder that can be congenital or acquired. In this disease, the eyeball has an elongated shape, because of this, the image of the object is in front of the retina, and not on it. A person with good eyesight sees all objects clearly, and a short-sighted person sees them more or less blurry. With a high degree of the disease, it is possible to clearly examine the object only if you bring it to the very nose. Under favorable conditions, myopia can decrease over time and even disappear, but most often it is the other way around.
What is myopiaIf you suddenly notice the first signs of the disease, it seems to you that objects began to look not as clear as before, your eyes began to get tired, headaches appeared - do not self-medicate, but urgently consult a doctor. Timely selection of contact lenses or glasses, vitamins, eye gymnastics or other treatment prescribed by an ophthalmologist will help stop the development of the disease and restore normal vision. If you do not take action in time, the case may end in an operation.
Acquired and congenital
Nearsightedness, or myopia, can be transmitted to a baby from parents, grandfathers or grandmothers, but it can be detected no earlier than three months. But even if a child was born with perfect vision, no one can guarantee that it will remain so for life. Vision can change over time, and not for the better. Myopia is especially common in adolescents. Prolonged tension of the eye muscles while reading books and watching TV, working at a computer, lack of sleep - all this leads to changes in the fundus. If parents do not take action on time, the child may gradually develop myopia, which will subsequently progress.
Myopia degree
Myopia can be mild, moderate, severe, and progressive, or malignant. In the most severe form of the disease, optic atrophy, retinal detachment and other complications, including complete loss of vision, can occur. Vision can begin to deteriorate at any age, both in a child and in an adult.
How to maintain normal vision?
To help your child avoid myopia, watch how he exercises. A first grader should read and write without interruption no more than 15 minutes, then he needs to rest, just not in front of the TV. For adults, prolonged work of the eye muscles at close range is also not recommended. In addition, it is advisable to do preventive eye exercises every day, for example, look alternately left, right, up and down, you can make circular movements with your eyes, close your eyes several times and open your eyes wide. Even when you are at work, take time to look at objects that are far away from you. You can look out the window at a nearby building or look at the sky. Changing the focal length is very beneficial for the eye muscles. These non-tricky exercises will help you maintain your eyesight for years to come.
