Gerontology: Retina "charges" 3 minutes to save vision loss over 40

Guide: Staring at crimson light for 3 minutes a day can significantly improve vision loss over 40 years of ageexample of a handheld LED flashlight used in the studyPhoto Source: UCLthe human body is an organic whole, but the process of aging each part has its prioritiesThe rate of aging is controlled to some extent by the metabolism of cells, which are controlled by mitochondria, which produce ATP to promote cell functionWhen mitochondria drop, they reduce membrane potential and ATP synthesisWhen this happens, mitochondria increase the production of reactive oxygen, which increases the inflammatory response, which is a signal of cell death, the retina ages faster than other organs, in part because of its high metabolic rateUsually, the eyes age from the age of 40With the loss of vision, glasses become an iconic feature of many middle-aged people in their 40s, a study led by University College London (UCL) found that staring at crimson light for three minutes a day can significantly improve vision loss over the age of 40This is the first time such research has been carried out in humansThe discovery could bring new light to eye therapy and could save the naturally impaired vision of millions of people around the worldThe findings were published in the journal GerontologyProfessor Glen Jeffery, of the UCL Institute of Ophthalmology,, said: "As we get older, the visual system decreases significantly, especially over the age of 40, and retinal sensitivity and color perception decreaseAnd as the population ages, this has become an increasingly important issueTo stop or reverse this decline, we try to restart the sensiator cells of the retina with short-term wavelight"
for people over 40, retinal cells begin to age, and this rate of aging is partly caused by the beginning of decline in mitochondria that produce energy and enhance cell functionMitochondrial density is greatest in retinal photosensitive cells and the need for energy is highAs a result, the retina ages faster than other organs, when ATP is 70%, and causes the sensor function to decrease significantly due to their lack of energy to perform normal functionsresearchers, based on previous studies in mice, bumblebees and fruit flies, found significant improvements in the function of retinal sensors when the eyes were exposed to 670 nanometers (long wavelengths) of dark red lightmitochondria have specific light absorption characteristics that affect their performanceAbsorbs longer wavelengths between 650 and 1000 nm to improve mitochondrial performance to increase energy generationThe photosensitive cells of the retina are made up of cone cells and viewrods, which mediate color perception, which provide peripheral vision and adapt to weak/dark lightto test whether the method works in humans, the researchers recruited 24 participants between the ages of 28 and 72 who had no eye disease (12 men and 12 women)At the beginning of the study, the eyes of all participants were tested for eye and cone cell sensitivityThat is, in adapting to dark light (pupil dispersion), participants are measured in the sensitivity of the viewrod by requiring them to detect dim light signals in the dark, and by allowing them to recognize color letters with very low contrast and increasingly blurry ness (a process called color contrast)all participants were given a small LED flashlight to take home and were asked to observe their 670nm crimson beam for three minutes a day for two weeksThey were then retested for the sensitivity of the eye-stick cells and the cone cellsresults showed that 670nm of light had no effect on young people, but in people in their 40s, the effect was significant, with significant improvements in the sensitivity of their eye cells (their ability to see things in low light), albeit below color contrastProfessor Jeffery said: 'Our study shows that improving vision loss is possible by simply exposing it to light and charging the energy system of the retinal cells, just like charging the battery The technology is simple, safe and low-cost (the cost of making the equipment is about 12 pounds) noteworthy, this method needs further in-depth study to verify the feasibility They say the eye is the window to the heart In daily life, pay attention to protect the eyes, especially stay up late party Even if there is no problem with vision, you should go to a professional ophthalmology hospital regularly every year to check the eye floor and vision References: s1 Dining eyesight ed by looking at deep red
