Staying away from the phone and staring at the screen for too long can make children short-sighted

If you're reading this on your phone right now, how many centimeters are your eyes from your phone? Is it 20 centimeters? Or 30 centimeters?

How long have you been staring at a screen today? If you're close to the average, it's probably more than nine hours, and if you find that your child has the same habits as you, you should be aware.

Staring at a phone or computer screen for too long could increase a child's risk of becoming short-sighted by 80 per cent, a new study has warned.

In a study of screen exposure and myopia in more than 3,000 people aged 3 months to 33 years, experts at Anglia Ruskin University in Cambridge, England, found a clear link between prolonged screen time and the development of myopia.

According to the study, smartphone use alone increased the risk of myopia by 30 percent compared with screen use, and excessive computer use increased the risk to 80 percent.

In 2019, the World Health Organization recommended that children under the age of two should have no screen time, and that children between the ages of two and five should have no more than an hour of sedentary screen time a day.

Screen injury 1: Cause eye pressure, increase the risk of myopia.

Eye doctors believe that the problem with staring at a screen too close for too long is not that the light is pointing directly at your eyes, but that it is the pressure on your eyes, resulting in eye strain.

Like cell phones, tablets, laptops, desktops... When our eyes focus closely on them, we blink less, and our eyes adjust to constant close viewing by forcing the pupillary muscles to stretch, easily causing the lens of the eye to shift.

Staring at screens for long periods of time, in adults, can cause eye strain and accelerate vision problems. For children whose eyes are still developing, the situation becomes even more serious.

Screen damage 2: blue light damage, resulting in visual impairment

Smartphones, tablets, laptops... There are artificial blue light sources, and long-term exposure to blue light can increase vision fatigue, premature aging of the eyes, and over time, continued exposure can even cause damage to retinal cells and vision problems.

The sun is the main source of blue light in nature, and while the exposure to blue light from screens is much smaller than that from the sun, the risk of damage is higher due to the proximity of the eyes to the screen and the amount of time spent staring at the screen.

Screen damage three: make it harder to fall asleep, affect vision development

The blue light emitted by many digital products can suppress the production of melatonin, causing circadian rhythms to be out of kilter, leading to delayed sleep and even inability to fall asleep. At the same time, playing mobile phones and tablets before bed is easy to cause excitement before bed, sleep deprivation, difficulty falling asleep and other phenomena.

Sleep quality is poor, not only can cause low immunity, spirit, be agitated, memory decline, at the same time also will affect the occurrence and development of myopia, especially in children and adolescents in the growth development period, lack of sleep can lead to insufficient growth hormone secretion, affect the growth of the eye, and prone to eye fatigue, adjustment disorder, cause eye myopia and myopic degree increase.

Today, "screen" has entered into every aspect of our life, large and small electronic screens, occupy our daily life, let us cannot leave it, also can't leave it.

For this we have been unable to escape the "harm", we have what methods can protect children's eyes, reduce the occurrence of myopia?

"Screen damage" mainly comes from three aspects: eye pressure, blue light damage, affect sleep, we can start from these three aspects, through the "create, change, supplement" three dimensions, myopia prevention of children's vision.

Create: Create a healthy lighting learning environment

For a healthy and adequate indoor lighting, it is necessary to ensure the use of two light sources at the same time, room lamp and eye protection desk lamp. In view of the different perception of light by children's eyes of different ages, it is crucial to choose professional anti-blue light eye protection lamp designed for different ages.

Change: Change your child's bad behavior

1, do not stay indoors for a long time, go outdoors more activities

Outdoor sunlight can promote the human body to secrete more dopamine and vitamin D, inhibit the growth of eyeball, axial elongation, and control the occurrence and development of myopia has a good preventive effect.

At the same time, sunlight contains a lot of near-infrared light (NIR red light), which is beneficial to human body, and has a good effect on improving and nursing vision.

2. Avoid staring at screens for long periods of time and use the "20-20-20" rule

After looking at a screen for 20 minutes, look up 20 feet (6 meters) away for at least 20 seconds, while avoiding small text on a smartphone.

3. Don't get too close to the screen. Keep your distance

The smaller the screen, the closer it is, the more damage blue light can do and the more pressure it can put on the eyes. To encourage children to study on larger screens, the priority is ultra-short focus laser TVS, projectors, TVS, desktops, laptops, tablets and mobile phones.

4. Turn off digital devices at least one hour before bed to reduce exposure to blue light and help children fall asleep earlier.

Supplement: Supplement low power NIR red light

Studies have found [1] that under the harm of blue light, the concentration of cytochrome C oxidase in the mitochondria of cells will gradually decrease with time, thereby reducing the metabolic capacity of visual cells and leading to visual decline and myopia, which is the main cause of visual damage caused by blue light.

According to a study conducted by the Institute of Ophthalmology, University College London, 3 minutes a day to receive specific NIR light waves in the infrared wave can effectively inhibit and repair the damage and aging of retinal mitochondria, and have a good blocking effect on the occurrence and progression of myopia, especially the damage caused by blue light! The test showed a 20 percent improvement in vision! [2]

Simply put, the deterioration of vision is directly related to the natural metabolic capacity of the eye cells, which need sufficient energy to carry out high metabolic rate. Near-infrared light can promote mitochondria in the cells to produce a large amount of ATP, just like to charge the cells of the retina, replenish energy, promote cell metabolism and regeneration, and have a good blocking effect on the occurrence of myopia.

Added for low power NIR red, children with time, can be more outdoor exposure to sunlight, and for children to stay indoors for a long time to learn, you can choose to have near-infrared light lighting equipment, such as professional brand of the lamp that shield an eye doctor Edward balder light, will be beneficial NIR "nearly flat red" red light and learning to work with embellish of eyes, The near infrared light of a specific wavelength acts on the retina to replenish the energy and make the mitochondria of retinal cells active, so as to play a nursing effect on the retina and eye cells, especially the damage caused by blue light.

In addition, the mix is also very important, this lamp configuration "light tomato model", every 45 minutes, through specific color temperature light changes, remind rest for 10 minutes, will also provide useful energy recovery during the period of light waves, help children enter a state of rest, let your eyes rest at the same time, through meditation and practice methods such as energy recovery, Set yourself up for another 45 minutes of productive study.

The lamp uses a safe, low-energy LED illumination developed by NASA, which is highly safe and does not cause damage even in close contact with the skin or for a long time. At the same time, the NIR red light penetrates so well that the energy can be absorbed by the mitochondria of the cell even when the eyes are closed.

For today's kids, it's definitely impossible to stay away from screens, whether it's online study, entertainment, making friends... The screen has become an important window through which they can learn about the world, access information and build relationships. However, for "screen injury", we can reduce the risk of children's myopia through some effective prevention measures, but also expect the joint efforts of society, school and family, as well as the use of more new technologies, so that children can understand the world through "screen" at the same time, have a pair of healthy and bright eyes.
