Pilot study successful: morning red light treatment helps against age-related poor eyesight
From around the age of forty, people begin to lose sight. This has also been the case in the past. The invention of glasses therefore led to a massive economic boost. Because craftsmen and other skilled workers were able to work significantly longer and better in old age. To this day, glasses are the means of choice to compensate for the deteriorating eyesight. Researchers at University College London have now developed another alternative: the morning red light treatment. They found out that the deteriorating eyesight is primarily related to the mitochondria in the eye. Because these produce significantly less energy in the form of the molecule ATP in old age. In animal experiments, however, it was shown some time ago that this process is not irreversible. Because when the eyes are irradiated with deep red and long-wave light, this stimulates the mitochondria to produce energy.
Color contrast vision improved by 17 percent
This effect has now been confirmed in a pilot study with human subjects. The participants were between 37 and 70 years old. One morning they had to look into an LED light with an output of eight milliwatts per square centimeter for three minutes. The result of the study was then quite impressive. The test subjects’ color contrast vision improved by an average of 17 percent. The effect also seems to last longer. Because even one week after the red light treatment, color contrast vision was still around ten percent better than before looking into the red light. However, it is crucial that the unusual radiation take place in the morning. Because when the researchers carried out the experiment once in the afternoon, there was no improvement in eyesight. The experts explained this with the changing work patterns of the mitochondria. They are therefore not always ready to receive
The first products could soon hit the market
From the researchers’ point of view, it is therefore clear: Evidence has been provided that red light irradiation significantly improves the eyesight of the human eye. A health hazard can also be excluded. Because the energy in red light is not significantly higher than in normal daylight. Now the challenge will be to bring a product that is ready for use on the market. In principle, however, this should not be a major problem. After all, there are already red light lamps today. The basic technology is already known and only needs to be modified. The researchers are therefore also optimistic that corresponding LED lamps will soon come onto the market. Potential buyers would then be extremely easy to use: they would only have to look at the red light for a few minutes in the morning.
