Nowadays, many people often "overuse their eyes" due to factors such as 3C products and working hours, so they gradually begin to pay attention to eye protection. A new British study pointed out that using "crimson LED light" to irradiate the eyes for three minutes in the morning can "rejuvenate" the eyes.
According to Scitech Daily, a research team at University College London (UCL) found that irradiating the eyes with deep red light with a wavelength of 670 nanometers (nm) for three minutes in the morning can effectively stimulate the energy-producing "mitochondrial cells" in the human retina and help restore vitality and sharpness to the eyes.
It has been reported that 20 subjects aged between 34 and 70 without eye disease were invited to conduct light exposure in the morning and afternoon respectively, and found that there was no improvement in the subjects' eyes when tested in the afternoon; However, if the eyes are irradiated for three minutes between 8 and 9 a.m., the "color discrimination" of the subjects can be increased by 17%, and the effect can reach more than 20% for older people, and the effect can last for up to a week.
In this regard, research professor Glen Jeffery explained that as we age, the cells in the retina of the eye also gradually age, and the rate of aging is due to the decline of energy-producing "adenosine triphosphate (ATP)" in the mitochondria of cells and the enhancement of cell function.
Previous studies have pointed out that light with wavelengths between 650~900 nanometers (nm) can activate mitochondria and improve their "work efficiency". Therefore, the light principle is like "wireless charging" of the eyes, and the function of some photoreceptor cells can be restored.
Because of its simple principle and no safety issues, Jeffrey is also developing inexpensive and easy-to-use home treatment devices to provide "affordable eye care" for more patients with color discrimination loss
