We all believe in miracles, especially on New Year's Eve! But do you know what is really a miracle? Close your eyes for a minute and then open and look around. Focus on any subject, lift your eyes to the light source, close again. And think about this: up to 80 percent of information comes to us through our eyes. Isn't it a miracle? We wish you a clear, healthy vision and want to acquaint you with this amazing, complex and incredibly intelligent organ - the eyes. Essilor Academy specialists have prepared 10 amazing facts related to eyes and vision.

How do we see?

There are two kinds of cells in the human eye: rods (there are about 120 million of them) and cones (there are much less of them, only 7 million) - these cells are responsible for the functions of the retina. They convert light into nerve impulses and allow you to see colors. In bright light, the cones work, and in the dark, the rods help to see. It is because of the individual sensitivity of the sticks that different people see in the dark with different clarity.

Why do pirates wear an eye patch?

Not only pirates, but also many sailors in the past sported dashing armbands. Do you think the reason is the absence of an eye? The pirates in the conditions of a severe naval battle were forced to quickly move between the brightly lit deck and the dark hold, and they did not have precious minutes to adjust their vision - the bandage helped out. The eye closed from the light remained in night vision mode. And the pirates were equally well oriented both in the light and in the dark. The dressing became the prototype of the modern Crizal Transitions photochromic lenses, which darken in a matter of seconds in bright light and brighten in a dimly lit room.

Glasses are the oldest method of vision correction

The first mention of glasses dates back to 1298. In 1305, the Dominican Giordano da Rivalto writes: “Not even 20 years have passed since the art of making glasses was discovered to improve vision. This is one of the best and most essential arts in the world. " Glasses are the oldest, as well as the simplest and most effective way to correct vision. It is interesting that the oldest companies in the field of optics arose just at the time of the formation of ophthalmology as a separate science. In 1849, the Essel Eyeglass Masters Society was founded in France. In the 20th century, it merged with Silor to form the world famous optical company Essilor.

Only humans have the whites of the eyes

Yes, it's incredible, but it is! Please note that all animals lack proteins in their eyes. Even the animals closest to man, monkeys, have completely black eyes. Therefore, emotions can be determined only by a person's eyes. By the eyes of a monkey, it is completely impossible to understand not only its feelings, but also the direction of its gaze.

Seeing an ophthalmologist can help diagnose diabetes

If you have one hundred percent vision, you shouldn't neglect going to an ophthalmologist. It is during an eye examination that a dangerous disease, which is usually asymptomatic, can be detected - type 2 diabetes mellitus. In this disease, the back of the eye is strewn with tiny burst blood vessels. Essilor Academy ophthalmologists recommend having an eye exam at least once a year.

Eat carrots or not?

They say that eating a lot of carrots will help your eyesight. The beta-carotene in carrots is very beneficial, but there is no direct link between it and vision. And the legs of this myth have been growing since the Second World War, when the British invented the newest night vision radar. To conceal the existence of the device, the British Air Force said their pilots were detecting planes at night thanks to a carrot diet.

All brown-eyed are actually blue-eyed

Scientists have proven that people with brown eyes are actually blue-eyed. The blue color is hidden under the brown pigment of the iris. Depending on the thickness and intensity of this pigment, brown eyes can be either light or dark, almost black. There is even an operation to remove brown pigment.

How to make green eyes even greener?

Shades of purple and plum will help enhance the color of green eyes and turn them into shining emeralds. Blue eyes will turn into azure eyes with brown and gold eyeshadows. And you can make brown eyes even deeper and more expressive by painting them with shadows of a gray scale. If you are a man, you can highlight the color of your eyes with colored eyeglass frames. Even a subtle shade of the frame will give your eyes even more depth and expressiveness.

How to check your eyesight at night?

The easiest and most exciting way to test your eyesight is to find the constellation Ursa Major on a clear night in the starry sky. If you can see eight stars instead of seven, your vision is perfect! The same eighth sprocket is located in the handle of the bucket near the middle sprocket.

What animals wear glasses?

Of course, these are toy animals. And you can be convinced of this by visiting GUM during the New Year holidays, where the traditional charity project "New Year Trees on Red Square" takes place. Each participating company decorates a Christmas tree for the auction in support of the Vera Hospice Fund. The Crizal brand is participating in this project for the first time and presents its blue and white Christmas tree, decorated with fairy-tale characters and beasts with glasses.

Enjoy the New Year and Christmas holidays, invigorating frosty air and sparkling snow. Don't worry about your eye health: glasses with Crizal lenses will do it for you!
