The Clinical Myopia Profile http://datingranking.net/pl/farmersonly-recenzja classification was used to assess the number of hours that children spent each day doing near-vision tasks. In 2016, 2017, and 2019, 34.7% of children spent more than 3 h a day doing these types of tasks, 25.9% spent between 2 and 3 h a day doing near-vision activities, and 39.4% spent <2 h a day performing said tasks.
3% of the children who participated in this study spent more than 50% of the said time using them. Only 34.2% spent <25% of the time using them and 27.5% spent between 25 and 50% of the time doing so. From 2016 to 2019 fewer children have near vision activities or excessive screen time of > 3 h and more children have screen time of 1–2 h and the details of the data obtained every year (Table 1). Several programs to improve the lifestyle of children have been established over the last few years; consequently, parents are well aware of the risks that their children face by spending long hours in front of a screen.
The number of hours spent in near vision and the use of electronic devices increase significantly with age, with this number being higher in children aged 7 years (OR:1.02; CI:0.99-1.94; p < 0.05). Thus, older children are spending more time on devices, especially those with excessive screen time > 3 h (Tables 2, 3). The increasingly frequent use of digital devices, both at home and at school, means that children are becoming more and more dependent on them as they grow older.

Table step three. Regularity shipment of your energy spent when you look at the near attention, using digital gadgets along with outside factors with regards to the children’s age.
About the spherical comparable value, the greater number of day spent into the close-eyes points and making use of electronic devices, the greater significant the fresh new development into the myopization (Dining table 4). In addition, tall differences were noticed when you compare what number of times spent from inside the close attention things from the various other autonomous teams out-of The country of spain (p ? 0.001).
Hence, discover a very clear association within continuously entry to digital equipment therefore the improved incidence out of myopia (OR: step one.step one0; CI: step 1.07-step 1.13; p ? 0.001) (Figures dos, 3).
According to research by the Scientific Myopia Character class, 50.6% of children who took part in the study invested ranging from 0 and you may 1.6 h exposed to Ultraviolet white each day, 33.2% ranging from step 1.6 and you will dos.seven h twenty four hours, and simply sixteen.2% spent over step three h day outdoors (Desk dos, Profile cuatro). Myopia decrease while the time invested confronted with the brand new Ultraviolet white grows might be observed (p ? 0.001) (Shape 5). Furthermore, what amount of period one to college students invest external minimizes as we grow old (Desk step 3) (p ? 0.001).
Within analysis, we had three chief results. First and foremost, the increased time used on near activities and using digital equipment are with the high prices away from myopia into the Spanish children. Secondly, frequency cost out-of myopia in kids old 5–7 age was growing. Thirdly children who had been said to invest more time external were less likely to want to establish myopia
Regarding the first finding, we have got that the time spent doing near activities has a direct impact on the prevalence of myopia in children aged between 5 and 7 (OR>1). Nevertheless, when we checked the time of these near activities that children spend with digital devices, we have got that the percentage of 7 years old children that spent more than 50% of the time doing near activities with electronic devices is higher than in children of 5 and 6 years old. Our study shows that, in general, the more the time using digital devices the higher the myopia prevalence (OR>1). But it is important to point out that we have found differences with age, meaning that we have not got a relation in the use of digital devices and myopia in children of 5 and 6 years old, but there is a relationship in children of 7 years old. Multiple studies also sustain that excessive use of smartphones, computers, television, etcetera, as well as the hours spent doing near-vision activities, have a negative impact on vision, and increase the risk of developing problems (15, 26, 31). For instance, the prevalence of myopia in children from Sydney (n = 124) was compared to the same in children from Singapore (n = 628), finding that it was higher in Singapore (29.1 vs. 3.3%) as a result of the differences in the children’s lifestyles of both countries, considering that in Singapore they spent more hours reading books and doing near activities while in Sydney spent more time in outdoor activities (13,75 vs. 3,05 h a week in Singapore) (21). Other researchers have related a higher risk of developing myopia with shorter distances for reading (<20 cm) and longer and continuous periods (>45 min), instead of joining to the total time in near activities (17). In this sense, a recent study has concluded that results are mixed and that more studies are needed to evaluate the association between screen time and myopia (36).
