For decades, scientists have been looking for explanations as to why certain conditions occur with age—like memory loss, slower reaction time, insomnia and even depression. They have scrupulously investigated such suspects as high cholesterol, obesity, and inactive lifestyle. Now there appeared a new culprit: the eye.

Circadian rhythms—are the physiological processes that rally the body in the morning to tackle daily demands and slow it down at night, allowing the body to rest and repair. This internal clock “relies” on the light to function properly. The studies have found that people whose circadian rhythms are out of sync, like shift workers, are at a greater risk for a number of ailments, including insomnia, heart and oncological diseases. 

So-called photoreceptive cells in the retina absorb sunlight and transmit it to a part of the brain, called the suprachiasmatic nucleus, which governs the internal biological clock of the body. The suprachiasmatic nucleus adjusts the body to the environment by initiating the release of the hormone melatonin in the evening and cortisol—in the morning. Melatonin is thought to possess many health-promoting functions. 

It was not until 2002 that the group of doctors of the University of Kansas discovered that photosensitive cells in the inner retina are directly responsive to the brain and particularly perceptive to the blue part of the light spectrum. 

In a study published by The British Journal of Ophthalmology, scientists of the University of Kansas made the following estimations: by the age of 45 photoreceptors of an average adult perceive just 50% of light. This percentage is sufficient for the normal circadian rhythm. By the age of 55, it reduces to 37% and by the age of 75—to a mere 17%. 

The scientists have compared how quickly exposure to bright light suppresses melatonin action in women in their 20s versus women in their 50s. The amount of blue light that significantly suppressed melatonin in the younger women had absolutely no effect on melatonin in the older women. 

Researchers in Sweden studied patients who had cataract surgery and been implanted with clear intraocular lenses. They found that the incidence of insomnia and daytime sleepiness was significantly reduced for this category of patients. 

Ophthalmologists believe that with age, people should make an effort to expose themselves to bright sunlight or provide bright indoor lighting at home. Seniors are at particular risk, because they spend more time indoors. 

In the modern society, most of the time we live in a controlled environment under artificial lighting, which is 10 000 times dimmer than sunlight and of the wrong part of spectrum. So it is recommended to install daylight and fluorescent lamps, and of course to take vitamin and mineral complexes to offset ageing of the eyes. 

Biologically active food supplement Safe-to-see created by the Vision company reduces the risk of eye retina diseases and eyesight impairment. Bilberry extract contains antioxidants, necessary to neutralize toxins produced in the retina and to protect eyes from the negative impact of environment. Safe-to-see food supplement—is a balanced vitamin complex with zinc, selenium, polyunsaturated fatty acids of the omega-3 family, and lutein, that improves eyesight acuity and reduces eye-strain. 

Do you spend all day in front of the computer screen? Or read in the public transport? With the Safe-to-see food supplement you may forget concerns for your eyesight. 

Apart from that, Vision has developed a special program, called “Eyesight”, that includes several food supplements. In addition to Safe-to-see food supplement it contains:

  • Antiox+—the ultimate antioxidant source;
  • Pax+ forte/Pax+—enriched with the vitamins of the group B, responsible for the eyesight acuity;
  • Senior—the source of beta-carotene and vitamins of the group B;
  • Vinex—contains grape powder and grape extract that are powerful antioxidants, protecting eyesight and the body from the aggressive impact of environment;
  • Nature Tan—is rich in beta-carotene and contains grape extract and cellulose that together maintain perfect eyesight for many years to come;
  • Brain-o-flex—polyunsaturated fatty acids of the omega-3 family and Ginkgo Biloba, as well as vitamin E and beta-carotene within its ingredients protect eyes from the destructive effects of free radicals.

Don’t be worried about your eyesight if it is guarded by Vision food supplements.
