Preventing myopia, protecting eyesight and eye exercises start with the rational use of iPad~

Abstract: high intensity and long-time close work can lead to the temporary decline of far vision, which is due to the high intensity of human eye regulation system when viewing objects at close range. Some studies have confirmed that children and adolescents will have spasms of regulation after reading for more than 40 minutes, It causes reading related temporary myopia (NITM), and NITM is closely related to the occurrence and progress of myopia.

electronic products, including computers, televisions, mobile phones, iPads, handheld game consoles, etc., have become an indispensable part of modern people’s life, but long-term uncontrolled use will cause certain damage to eyes and physical health.

Video terminal syndrome

,

and “video terminal syndrome” refer to the terminal operation of optical display (such as computer monitors, data input, televisions, video game consoles, etc.), causing a series of symptoms, including visual fatigue symptoms such as eye congestion, dryness, foreign body sensation and increased secretion, as well as acid swelling fatigue in neck, shoulder, back and arm. It can be manifested as temporary decline in visual acuity, decreased adjustment sensitivity, decreased fixation ability, dry eye, myopia and so on Deep wait.

and

high-intensity and long-term close work can lead to the temporary decline of far vision, which is due to the high-intensity state of human eye regulation system when viewing objects at close range. Some studies have confirmed that children and teenagers will have spasms of regulation after reading for more than 40 minutes, It causes reading related temporary myopia (NITM), which is closely related to the occurrence and progress of myopia.

the harm of electronic products

As a specific object that needs to be operated in close range, the damage to the eyes of electronic products after long-term use includes not only the impact of close range operation on the eyes, but also the characteristics of its electronic display terminal. High brightness display screen, high brightness contrast caused by lack of background lighting, screen glare caused by poor room lighting angle, etc. will pay more attention to fatigue and over adjustment. The fast changing content of electronic products will often reduce the blinking times of users and reduce the secretion of tears; The radiation of electronic screen can also aggravate tear evaporation and dry eye symptoms. Children with

and

should develop good habits of using electronic products. As a special group, children with

and

are still in the development stage of ocular refraction, can develop myopia under the influence of bad visual habits, and have poor autonomous control over the methods of using electronic products. Therefore, they are high-risk groups for the use of electronic products. However, electronic products are a special carrier for children’s learning. We should develop good use habits and minimize their impact on children’s visual development.

how to prevent eye damage caused by electronic products

1. Pay attention to the distance when reading electronic products.

and

try to keep the distance between the display screen and eyes more than 20-30cm, reduce the adjustment demand during reading, and try to choose products with larger screen. Because the smaller the screen, the easier it is for the user to shorten the reading distance.

2. Pay attention to the ambient lighting when reading.

and

try to provide ambient lighting at the back of the screen to reduce the relative brightness of the screen and reduce the symptoms of visual fatigue, but it is best to use floodlighting as the illumination source to avoid screen reflection.

3. Pay attention to the use time.

and

for you who have been chasing Korean dramas for a long time, this best description is: enough is enough. The method of reading for many times and reading for a short time shall be adopted, and the continuous reading time shall not exceed 1 hour each time, so as to reduce the impact of accommodation spasm on myopia. It is advisable to have an interval of 10-15 minutes each time. Overlooking distant or green objects can relax the adjustment system of human eyes.

4. As a special group using electronic products, children need to pay more attention to their use.

and

are the key period of children’s refractive state development before the age of 14, and do not tend to be stable until the age of 18. During this period, they often have heavy study and work and are keen on electronic products. The occurrence and development of myopia is very fast. Therefore, the refractive state examination once every half a year is particularly important. Timely glasses or behavioral intervention is very important for myopia prevention and control. Large sample multicenter clinical trials have confirmed that outdoor activity time is inversely proportional to the incidence of myopia, which is a really effective protective behavior. Therefore, reducing the use of electronic products and increasing children’s outdoor activity time is an effective way to prevent myopia.
