The Clinical Myopia Profile 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 https://datingranking.net/pl/e-chat-recenzja/ 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.

Dining table step 3. Volume delivery of energy spent in near sight, using digital products and also in outdoor points with respect to the children’s many years.
Regarding the round similar well worth, the more date spent in the near-vision activities and making use of gadgets, the greater amount of high the fresh pattern towards the myopization (Desk cuatro). Additionally, tall distinctions have been seen when you compare what number of period spent inside near attention things in the additional independent communities out of Spain (p ? 0.001).
Thus, there clearly was an obvious organization between the too-much the means to access digital gizmos while the improved incidence away from myopia (OR: 1.step one0; CI: step 1.07-step 1.13; p ? 0.001) (Rates dos, 3).
Outdoor Items
In accordance with the Clinical Myopia Profile classification, 50.6% of the youngsters just who participated in the study invested anywhere between 0 and 1.6 h met with Uv light each day, 33.2% ranging from 1.six and you can 2.7 h a day, and just sixteen.2% spent over step three h a day outside (Dining table 2, Figure 4). Myopia minimizes since go out invested met with the new Uv light increases shall be noticed (p ? 0.001) (Contour 5). Also, what amount of days one college students spend outdoors reduces as we age (Table step 3) (p ? 0.001).
Talk and you will Findings
Within this analysis, we had about three chief findings. First and foremost, the elevated go out spent on close activities and using electronic equipment is actually of the high cost off myopia in Language students. Furthermore, incidence costs out of myopia in children old 5–eight decades try growing. Thirdly children who have been advertised to invest longer outdoors had been less likely to want to generate 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).
