Myopia is a disease linked to various eye problems and is considered the main cause of irreversible visual impairment in the elderly.
But this pathology is normally acquired in childhood and the disease seems to be caused by genetics, insufficient time outdoors, and many years of being in college classrooms.
The Centers for Disease Control and Prevention Diseases (CDC), states that approximately 1 in 4 preschool-age children have an undiagnosed or untreated vision problem in the country.
Since many vision problems begin at an early age, they recommend that parents make sure they have their child’s eye exams regularly to keep them healthy. healthy.
As reviewed by Hindusta n Times, in a new study, researchers discovered five gene variants that increase the likelihood of becoming myopic as children get older.
However, few have been shown to increase risk specifically in those with related lifestyle variables.
At least 340 000 participants with European ancestry underwent genome study to identify genetic variants that make people more susceptible to myopia in combination with intensive schooling.
The study yielded five genetic variants that progressively increased the risk of becoming myopic for people, the more time they spent in school, especially for people who had attained college-level education.
According to the findings, three of are you going rians were previously unknown, while two were found in East Asian cohort studies, where around 80 % of children become myopic.
For comparison, around 30 % of children develop myopia in the West.
For this reason, 
researchers concluded that these findings provide new insights into the biological pathways that cause myopia, but more research is needed to understand how those pathways interact with factors lifestyle to cause the condition.
What eye exams can you do to your children
CDC recommends getting an eye evaluation which is a quick check. It can be done by a family doctor, pediatrician, school nurse, or other health care professional.
Another option is a complete eye exam, it is a little more rigorous than the previous one and is performed by a specialist of the eyes, who is also called an ophthalmologist or optometrist.
