Researchers have developed a cheap and home applicable therapy, the millions of people with age-related decreasing eyesight could help. In a study, it showed that the contemplation of a deep red light for three minutes per day, can improve the visual performance from the middle ages considerably.

For the study, the participants were given a small LED flashlight, which emitted deep red light of 670 nanometers. This kept you on a daily basis for three minutes directly in front of each eye. In the case of younger people, no improvement was shown in the case of subsequent eye tests, persons aged 40 years benefit, however: you have the ability to recognize colors increased by up to 20 percent. In the blue part of the color spectrum for the aging-prone, the effect was more pronounced. Also See in low light conditions improved, although to a lesser extent, as the researchers in the journal "The journal of Gerontology" reports.

In earlier studies had shown that the function of the sensory cells is improved in the retina of mice, bumblebees and fruit flies, if they were deeply exposed to red light.

Eyesight can diminish with age

Professor Glen Jeffery, from the Institute of ophthalmology at University College London, said: "Our study shows that it is possible to improve in older people with reduced vision due to Light wavelengths in the retinal cells decreasing charging energy system, significant, similar to the Charging of a battery."

In the retina of the eye, the sensory cells for vision are located. These require a particularly high level of energy by mitochondria, small "Kraftwerke" in the cells, will be covered. From the age of about 40 years, the cells begin to age and the provision of energy by the mitochondria decreases gradually up to 70 per cent. Due to the lack of energy the cells can perform their tasks increasingly worse. Long-wavelength light, your performance can be increased again.

Before such a therapy can be started, it must be checked the effect and the dosage of the “light shower” for the eyes of still in further studies.
