     Light passes through the cornea into the lens, a transparent part located behind the cornea, which focuses the light to fall on the retina.

 

     The focused light reaches the retina, a light-sensitive area located at the back of the eye, and when the image falls on it, it converts it into nerve signals.

      These Nerve signals (which are electrical signals in reality) travel through the optic nerve to the brain.

      The brain analyzes and interprets the signals, for example, it tells us that what we see is a delicious orange to eat or a hot teapot that may burn us.

 

      For this to happen, it is necessary for the image to fall evenly on the retina.

 

     However, if the image falls in front of the retina (known as nearsightedness) or behind the retina (known as farsightedness) or irregularly on the retina (known as astigmatism), the vision becomes blurry.

      With any of these vision defects, children may have difficulty seeing things clearly on whiteboards or screens in classrooms. 

 

      However, younger children may not express difficulty in vision, but they may exhibit the following behaviors indicating vision problems:

         Sqeezing eyes continuously

 

        Seeming unaware of distant objects

 

         Excessive blinking

 

         Rubbing their eyes frequently

          Sitting close to the television

 

          Therefore, it is important to have a child's vision examined in the first year of life, and at age three, especially if there is a family history of increasing nearsightedness and other eye conditions.

 

How is nearsightedness treated in children?

 

    The best treatment is prescribing suitable glasses so that the child can see clearly. We do not recommend the use of contact lenses for children before adolescence.

 

Can nearsightedness in children be prevented?

    Nearsightedness cannot be prevented because it is caused by genetic factors.

 

     Therefore, the focus should be on detecting the condition and treating it with suitable glasses.

 

   Does the glasses prescription change as the child grows?

     For nearsightedness, there are two possibilities with the child's growth and aging:

1- The first possibility:

The size of the eye stabilizes, and its growth does not increase, so the glasses prescription does not change.

2- The second possibility:

The eye grows, and its size increases, so the glasses prescription increases.

 

   This increase in glasses prescription does not indicate further weakening of vision, as commonly believed in these cases, but rather indicates that the eye has grown in size, and the glasses prescription has increased accordingly, as simple as that.

 

     For astigmatism, the same possibilities for changing the glasses prescription with growth apply as in cases of nearsightedness.

 

    For farsightedness, there are two possibilities with the child's growth and aging:

1- The first possibility:

The size of the eye stabilizes, and its growth does not increase, so the glasses prescription does not change.

2-The second possibility:

The eye grows, and its size increases, so the glasses prescription decreases such cases.

 

In the next video, Dr. Ossama Abdelhakim explains why the glasses prescription changes while the child grows.

 

   

    Neglecting your child's treatment for vision weakness and improving their visual performance exposes them to various vision problems and reduces their participation in recreational activities and social engagement.

 

     However, helping your child see well contributes to improving their quality of life and academic achievement, so treat them promptly."
