The study found that LED dark red light can improve the problem of vision loss

Now many people often "overuse their eyes" due to 3C products, working hours and other factors, and gradually began to pay attention to eye protection. And a new British study points out that using "dark red LED light" to illuminate the eyes for three minutes in the morning can "rejuvenate" both eyes.
According to Scitech Daily, the research team of University College London (UCL) found that irradiating the eyes with a dark red light with a wavelength of 670 nanometers (nm) for three minutes in the morning can effectively stimulate the "mitochondria cells" that generate energy in the human retina and help restore the vitality and sensitivity of the eyes.

It is reported that 20 subjects between 34 and 70 years old without eye diseases were invited to the experiment. After light exposure in the morning and afternoon respectively, it was found that if the test was conducted in the afternoon, there was no improvement in the eyes of the subjects; However, if the eyes are irradiated for three minutes between 8:00 a.m. and 9:00 a.m., the "color discrimination" of the subjects can be improved by 17%, and for older people, the effect can be more than 20%, and the effect can last for up to a week.

In this regard, research professor Glen Jeffery explained that with age, the cells in the retina of the eye will also gradually age, and this rate of aging is due to the decline of the energy producing "adenosine triphosphate (ATP)" in the cell mitochondria and the enhancement of cell function.
Previous studies have shown that light with wavelengths between 650 and 900 nanometers (nm) can activate the mitochondria and improve their "work efficiency". Therefore, the light principle is like "wireless charging" to the eyes, and can restore the function of some photoreceptors.
Because of its simple principle and no safety problem, Jeffrey is also developing inexpensive and easy to use household therapeutic instruments to provide more patients with color loss with "affordable eye treatment" (Source: Free Times)
