Description

Wearable reading monitoring device and operating method thereof

The invention relates to a wearable reading monitoring device and a method for operating the same, in particular to a wearable reading monitoring device capable of reminding a user to read ambient light, direct light intensity, reading distance, reading posture and reading time, and a method for operating the same.

According to the results of the “Epidemiology of Refractive Status of 6-18 Years in Taiwan” conducted by the National Health Service of the Ministry of Health and Welfare of the Executive Yuan, the prevalence of myopia in first-year children of the National Primary School was 75 years. 3%, climbed to 17.9% of the Republic of China in 1999. The 103-year survey of the Ministry of Education on the visual acuity rate of the national and middle school students also showed similar results. The proportion of students with first grade primary school students with poor eyesight (the average eyesight of both eyes was less than 0.9) was 26.83%, and The annual increase rate of visual acuity is about 8%, the proportion of poor eyesight in the sixth grade of primary school reaches 64.55%, and the proportion of poor overall vision in the third grade (grade 9) is as high as 76.58%, indicating that the problem of myopia in schoolchildren is becoming more and more serious.

At present, the causes of myopia formation are still under study. Possible factors include genetics, environmental factors, behavioral factors, premature birth, hypoplasia, diseases and eye diseases. Environmental factors and behavioral factors can achieve the goal of slowing or avoiding myopia through artificial precautions. The methods of preventing myopia recommended by the National Health Service include: a properly illuminated reading environment and reduced closeness Reading, avoiding long-term close-up use of the eyes, reading (or watching TV) 30 minutes of rest, 10 minutes of outdoor activities, more than 2-3 hours of outdoor activities and balanced nutrition.

Because modern people have a lot of opportunities for close-up use of the eye, especially the large number of computers and mobile phones, the long-term use of eyesight, causing a huge burden on the eyes, and even the eyes can not rest well. With the development of science and technology, the increase in the rate of myopia has also led to an increase in the number of myopia. The reason is mostly because there is no proper reading distance.

In addition, because of the increased time for modern people to use smart phones and tablets, the eyes will also be exposed to light damage. Because the illuminating source is from the illuminating diode, the illuminating diode generates a large proportion of short-wavelength blue light. In theory, the blue light belongs to the more powerful visible light. When the eye is directly looking at the electronic product screen for a long time, the blue light will penetrate the cornea and Direct injection of the crystal into the macula is highly likely to cause chronic damage to the macula. In the dimly lit environment, the use of electronic products, the direct glare of electronic products and the dim light of the surrounding light makes the contrast of light stronger, which leads to visual fatigue of the eyes and causes certain damage to the retinal cells.

According to the National Health Service, the two most important factors for vision care are reading distance and reading time. However, the correctness of the reading distance value is closely related to the reading posture. Compared with the distance between the desktop measuring device and the body of the reader, the wearable device can more accurately measure the distance between the reader's eyes and the reading object, and As the user's posture changes, the target distance of the viewing changes, and instant monitoring is performed. In addition to the poor reading position may lead to inaccurate reading distance measurement, more importantly, it is easy to cause cervical degenerative changes and cervical disc herniation, which may further cause shoulder and neck pain, dizziness, headache, poor memory and other issues.

As can be seen from the foregoing, the correct eye habit includes conditions such as reading time, reading distance, and reading posture, so that in order to provide a wearable reading monitor with prevention of myopia It is quite important and urgent to reduce the myopia rate of modern people. It is necessary to develop a new wearable reading monitoring device to improve the accuracy of wearable reading monitoring and reduce the manufacturing time and manufacturing of the new wearable reading monitoring device. cost.
