Solar flare: the benefits and harms of an optical natural phenomenon

"Sunlight, sunrises and fogs ..." - these beautiful words of the song carry thoughts to the summer meadow, where the rain is dewy, the sun shines in the lake . In the morning nature wakes up and thanks for the light and warmth the main source of life is the Sun. We take his light and warmth as a matter of course, and sunbeams on the water and in puddles are able to cheer up. How does the sun flare? Do you know how useful solar "bunnies" and what are dangerous? We ask specialists.

Solar flare from space

The optical phenomenon, when the sunlight is reflected from the water surface at the same angle as the camera of the sensor from the satellite or spacecraft looks at the same surface, causes the sunlight to stain the water in unusual luminous shades. The currents and waves of water bodies that are constantly in motion scatter the rays of the luminary in different directions, and the photographs of the water surface are obtained by diffuse, chaotic bands of light. For some, this phenomenon is difficult, for example, to oceanologists, who disobedient solar rabbits interfere with the finding of phytoplankton and the real color of the ocean on the satellite images. And there are scientists who "play" with glare of the sun with pleasure.

Solar bunnies in the service of man

Researchers of atmospheric phenomena and weather conditions are friends with such a phenomenon as sunlight glare. Photo of water bodies with which the sun has "played" allows to reveal gravitational waves and atmospheric circulation of air over the oceans, which are usually hidden from the eyes. Blurred places in photos from space, which have created glare, allow you to learn about the origins of winds and their directions. Scientists have also benefited from this phenomenon. Solar glare, reflected from the water spots on the water, helps to pinpoint their locations. This allows them to be detected regardless of their origin: natural or man-made.

With the sun carefully!

Affectionate and kind sun can be evil and dangerous, if you behave with him wrong. Much has been said about how to protect the skin from ultraviolet, and yet a cheerful sunlight can be dangerous for the eyes. Acute burn of the cornea of the eye is often obtained when skiing, flying on a hang glider over a pond, surfing and simply swimming in the bright sun. If you look at the sun at the zenith, you can get a retinal burn. Reflection of rays from water or a snow-white surface has a double effect, as a result of the eyes are strongly watered, there is a sharp pain, it happens that some time is simply impossible to watch. Everything passes quickly and is forgotten as quickly. This is a dangerous sunburn. Constant such exposure gradually kills tissues, damages the retina and cornea, leads to the development of cataracts.

The inhabitants of the equatorial countries, especially those living near the sea, are particularly prone to this phenomenon, eye damage is chronic. The "worn out" eyes here already take place by the age of 30-35. Eyes must be protected from glare correctly selected sunglasses.

To look at the sun is harmful? Useful!

At the same time, ophthalmologists actively use the photostimulation method to revitalize the eye. It is based on the fact that the eye is exposed to a directed beam of light. So does sunlight, but bright and not too strong. The best time to contemplate sunlight is sunrises and sunsets, when its light is not yet bright. Another way is to look at the sun with your eyes closed. How does it work? Under the influence of light, all the processes in the retina and in the whole organism are quickened and accelerated: metabolism is accelerated, the vessels expand, the work of the nerve endings and brain activates.

People often like to look at the fire - this sight fascinates and soothes. Another benefit of this exercise is that the flickering and pulsating light acts on the eyes as a non-contact massage.

It is necessary to know

Several scientifically proven facts will help maintain good eyesight:

• The most dangerous impact on the eyes of sunlight glare is not in the summer, but in the spring and autumn.
• The most unfavorable time for eyes is from 10 to 16 hours.
• Especially dangerous is the bright flicker for babies, and in fact their eyes near the water few protect. The kid is not always happy with points, it will be protected by a wide-brimmed panama. Sunbathing and swimming is better for him in the morning and evening.
• Enjoy the highlights on the water with glasses.
• The higher the position above sea level, the more dangerous is the exposure of the bright sun to the eyes.
