Did you know that an undetected visual problem can cause learning problems at school? When a child's visual acuity is not correct, he is limited in seeing correctly any letter or number written on paper or on the blackboard and, furthermore, this problem can also affect his motor development and his skill in fine motor skills.
Preventing and treating the problems derived from the visual health of children is the mission of the people who are usually with them. Parents and family members, teachers and caregivers must be very attentive to their behavior in order to detect visual problems in childhood early. Its early correction will avoid problems in school related to learning, attention and concentration.
If we observe that the child has certain behaviors or manias when he has to distinguish something from far or near, it is possible that he presents a problem with visual acuity. Some of these habits that can indicate that our child does not see correctly are:
1. It sticks a lot to the text. When children have difficulty seeing up close, they tend to draw too close to the book or paper to be able to read and distinguish the writing.
2. Adopt strange head positions in a sustained way. These are posture habits that are performed unconsciously to try to better focus images.
3. Lacks good judgment when choosing colors. If we observe that when painting or coloring their color combinations are not very correct, perhaps we are facing a color blind problem.
4. Stop paying attention. Visual difficulties can cause the child to lose interest in reading, games or explanations because they get tired.
5. It sticks a lot to the computer screen. It can be due to visual problems at medium or close range.
6. Acquire stale postures when writing. These bad postural habits can indicate a lack of visual acuity and are adopted in a habitual and unconscious way to try to focus and see better. Being aware of these signs is essential for both parents and educators. In the learning phase and especially when children begin to read and write, their progress can be severely penalized by vision problems.
Problems associated with an uncorrected visual defect can be refractive or graduation, including hyperopia, astigmatism, and myopia. These defects represent 20 percent of cases at school age. When these visual defects are not well corrected, they lead to other problems such as lazy eye or amblyopia and strabismus. Specifically, the latter represents 12-15 percent of the cases in the years of schooling.
A good correction of strabismus by surgery will allow us to have a fully functional eye, not only aesthetically corrected, but also visually. The risk of strabismus occurs when one of the eyes deviates and loses stimulus. Then, it becomes a lazy eye. In other cases, lazy eye occurs when there is a large difference in prescription between the two eyes, that is, one is fine and the other is very myopic. This is solved with optical systems and visual training.
When we do prolonged work in near vision, we have a reflex effect which is that of accommodation to be able to focus on objects at this short distance. If this task is carried out in a prolonged way, the evolution of myopia is evident and, very especially, after primary schooling, in university education.
Recent studies in collaboration with some universities have shown that in the first year the use of glasses stands at 10 percent, while the fourth year reaches 23 percent, mainly due to cases of myopia.
