The morning of almost all women begins the same way - with makeup. Someone makes a light make-up of two or three remedies, and for someone there is not enough a whole cosmetic bag.

You can realize your ideas with the help of materials for building presented on the site http: //nogt.rf

Only beautiful eyelashes can make eyes expressive and give a spectacular look. It would seem that they are so insignificant in our body that it is hardly possible to learn something interesting about them. But this is not so!

1.   At all times, it was believed that luxurious eyelashes - an indicator of human beauty and health. But there are exceptions. In the north of Tanzania, there is still the Hadza tribe, whose representatives cut their eyelashes, as it is customary to get rid of the hairline throughout the body.

2.   Eyelashes grow only in representatives of the mammalian order.

3.   From a biological point of view, eyelashes are bristly hairs that grow in 1-2 rows on the lower eyelid and 2-3 rows on the upper.

4.   The average number of eyelashes on the upper eyelid is about 200 (length - about 10 mm), on the lower - about 130 (length - about 6 mm).

5.   The main function of eyelashes is protective. They prevent the ingress of dust, dirt, insects into the eyes.

6.   Eyelashes grow throughout life, but due to aging processes, their growth slows with age.

7.   Eyelashes renew in approximately 3 months.

8.   Sometimes babies are born at all hair, but all babies have eyelashes, because they begin to form in the womb.

9.   The total length of eyelashes falling over the whole life is more than 30 m.

10.   Some medications may affect eyelash growth. For example, antipyretic and analgesic drugs based on paracetamol, ibuprofen and aspirin can slow down this process.

11.   Eyelashes are 97% keratin protein, and 3% water.

12.   The color of eyelashes depends on the yellow, red and purple pigments contained in the upper layer of hairs.

13. The eyelash has its own special structure - the core, root and follicle. A blood vessel that nourishes the hair is suitable for each follicle. At the base of the eyelashes there are sebaceous glands, the secret of which prevents drying out and brittleness.

14.   Eyelashes are the thickest, toughest and darkest hairs on the human body.

15.   Among the popular folk remedies for eyelash care are castor, pink, coconut, peach, almond, olive, burdock, camphor, argan oil. You can add vitamin A, which promotes the growth of eyelashes.

16.
  In modern preparations for eyelash growth, additional ingredients are added that contain vitamin B5 for strengthening, and compounds for retaining moisture, such as glycosaminoglycans. The effect is visible when using funds and quickly disappears after application.

17.   Among animals, thick and long eyelashes have camels.

Ostrich eyelashes make brushes. And the eyelashes of rhino birds look like feathers. Curiously, cats do not have eyelashes.

18.   The longest eyelashes belong to Phuto Rav Mauli, a resident of the Indian province of Mesok. Representatives of the Guinness Book of Records recorded the fact that the length of his eyelashes was 4.7 cm.

19.   It is believed that if you cut your eyelashes, they will not grow anymore. It is not true.

20.   Among the reasons that can cause eyelash loss:

- stress;

- the use of low-quality cosmetics or allergies to its components;

- lack of iron in the body;

- fungal and autoimmune diseases;

- demodex (facial tick);

- hormonal disorders.

To Oily eyelashes beautiful, thick and healthy, you need to take care of them. In conclusion, a few simple recommendations:

Use only high-quality cosmetics with a good shelf life.

Do not experiment with eye and eyelash products without first consulting a beautician or doctor.

Only grow eyelashes from specialists, make corrections on time.

Always remove makeup from the eyes.

Vision is the main receptor for the long and short orientation of birds. Unlike other vertebrates, among them there is not a single species with reduced eyes. The eyes are very large in relative and absolute sizes: in large predators and owls in volume they are equal to the eye of an adult. The increase in the absolute size of the eyes is beneficial because it allows you to get large image sizes on the retina and thereby more clearly distinguish its details. The relative sizes of the eyes, which differ in different species, are associated with the nature of food specialization and hunting methods. In predominantly herbivorous geese and chicken eyes, the masses are approximately equal to the mass of the brain and make up 0.4–0.6% of the body weight; in those catching mobile prey and looking for it at large distances of birds of prey, the eye mass is 2-3 times greater than the mass of the brain and is 0.5-3% of body weight, in owls active in twilight and at night, eye weight is 1-5% of body weight (   Nikitenko M.F.).

In different species per 1 mm2 of retina, there are from 50 thousand to 300 thousand photoreceptors   - rods and cones, and in the field of acute vision - up to 500 thousand - 1 million. With a different combination of rods and cones, this allows you to either distinguish many details of the object, or its contours in low light. The main analysis of visual perceptions is carried out in the visual centers of the brain; retinal ganglion cells   respond to several stimuli: contours, color spots, directions of movements, etc. In birds, like in other vertebrates, the retina has a site of most acute vision with a depression (fossa) in its center.

Some species that feed mainly on moving objects have two areas of sharp vision: daytime predators, herons, kingfishers, swallows; Swifts only have one area of \u200b\u200bsharp vision, and therefore their methods of catching prey on the fly are less diverse than that of swallows. In the cones are oil drops   - color (red, orange, blue, etc.) or colorless. Probably, they play the role of filters that increase the contrast of the image. A very mobile pupil prevents excessive flare of the retina (during quick turns in flight, etc.).

Accommodation (hinting at the sharpness) is carried out by changing the shape of the lens and its simultaneous movement, as well as some change in the curvature of the cornea. In the area of \u200b\u200bthe blind spot (the location of the optic nerve) is located crest   - a vessel-rich fold formation protruding into the vitreous (   fig. 60, 13) Its main function is to supply the vitreous body and inner layers of the retina with oxygen and remove metabolic products. There is a crest in the eyes of reptiles, but in birds, apparently, due to the large size of the eyes, it is much larger and more complex. The mechanical strength of large eyes of birds is ensured by thickening of the sclera and the appearance of bone plates in it. Moving eyelids are well developed, with some birds bearing eyelashes. The blinking membrane is developed (   third eyelid), moving directly on the surface of the cornea, cleansing it.

In most birds, the eyes are located on the sides of the head. The field of view of each eye is 150-170 *, but the field of binocular vision is small and in many birds is only 20-30 *. At owls   and some birds of prey, the eyes are shifted to the beak and the field of binocular vision increases. In some species with convex eyes and a narrow head (some waders, ducks, etc.), the total field of view can be 360 \u200b\u200b*, while narrow (5-10 *) binocular fields of view are formed in front of the beak (facilitates the setting of prey) and in the neck (allows you to estimate the distance to the enemy approaching from behind). In birds with two areas of acute vision, they are usually located so that one of them is projected into the field of binocular vision, and the other into the region of monocular vision (

For example, a bird-secretary will offer a non-standard curling technique “inside”. The llama can take on a snow-white color. The camel, which is the animal with the longest eyelashes in the world, will help you choose the length. They can reach 5 cm, their thickness and increased “hairiness” protect the host from sand. But the most unusual discovery will be minimalism (and in general the presence) of eyelashes of a representative of scaly - snakes.

The eye of a camel has three centuries. Two, with eyelashes, protect from sand. The third, very thin (blinking membrane), works like a wiper, washing away contaminants from the eyes. This eyelid moves horizontally, not up and down. In addition, a camel can see through it a little. On a sandstorm or windy day, these eyelids protect your eyes from the sand, while the camel continues to walk
