Protecting eyesight and preventing myopia with the power of science

The Worsening Problem of Myopia in Japanese Children

With increased long-term use of PCs and smartphones, health problems such as eye discomfort, eye strain, dry eyes, and "smartphone myopia" due to blue light exposure have become a social issue. Furthermore, according to data from the Ministry of Education, Culture, Sports, Science and Technology, the decline in children's eyesight in recent years has been remarkable, with the percentage of children with uncorrected visual acuity "below 1.0" reaching 37.79% for elementary school students, 60.93% for junior high school students, and 67.80% for high school students in 2023.

Scientific Explanation of the Causes of Myopia

Myopia is not a simple genetic problem. Research shows that excessive exposure to intense artificial light (especially blue light) disrupts the balance of dopamine secreted in the retina, causing excessive eye growth and increasing the distance between the lens and the retina, thereby inducing and progressing myopia.

Natural light, on the other hand, effectively stabilizes dopamine rhythms, suppresses abnormal eye growth, and fundamentally reduces the risk of myopia onset.

This finding not only clarifies the cause of the recent sharp rise in myopia rates but also indicates a clear direction for prevention and countermeasures: building a high-quality lighting environment that mimics natural light is a core strategy.

Mitigating the Progression of Myopia

In an experiment conducted by the Singapore Eye Research Institute (SERI) in 2020 on the relationship between light and myopia, chicks were housed under fluorescent lights and natural light LEDs for two weeks, and the recovery status of their myopia model was compared.

The experiment showed that the myopia recovery effect in chicks under natural light LED illumination was significantly superior to that in the fluorescent light group. This light source not only slowed the progression of myopia but also increased choroidal thickness, contributing to a faster correction of refractive errors.

The principle is that such lighting highly reproduces the spectral characteristics of natural light, giving the eyes a positive effect similar to an outdoor light environment, and as a result, effectively preventing and suppressing myopia.

Visual Comfort Increased by 1.2 Times

A study at the University of Basel in Switzerland investigated the effects of natural light LEDs on eye comfort, melatonin, mood, alertness, and sleep in 15 healthy subjects aged 19-35 over 2-3 weeks.

The experiment showed a significant improvement in eye comfort and a clear reduction in visual fatigue for subjects in a natural light illumination environment. This lighting excelled in balancing brightness and color temperature, resulting in an overall comfort score 1.2 times higher than general lighting.

Eye Strain Reduced by 4.3 Times

Seoul National University College of Medicine conducted a controlled experiment in 2018 with 34 adults aged 20-49, comparing various indicators such as visual fatigue, blurriness, and sensitivity to light in users under normal lighting and natural light illumination.

The experiment showed that users of natural light illumination experienced a 4.3 times reduction in eye strain symptoms compared to users of general lighting. At the same time, subjects reported clearer vision, softer light, faster onset of sleep, and improved sleep quality.

Embracing Natural Light to Protect Children's Future

In an environment where educational burdens are intensifying and digital device use is starting at younger ages, myopia prevention is no longer just an individual health choice but a shared responsibility for families and society. Introducing lighting that closely mimics natural light can effectively alleviate eye fatigue and suppress the onset and progression of myopia, as well as provide 24-hour visual protection during a child's development.

We believe that by leveraging the power of science and returning to the spectrum of natural light, all children can have the opportunity to experience a clearer, brighter future.
