is martin the degenerates to musicians under the swastika, a documentary about this sounds of power, inspiring story about survival of the home of the go get the tennis. i was the only one who lives in nazi germany. watch now on youtube dw documentary, the look deep into my eyes. what do you see? we can tell through eye contact whether someone's well disposed towards us that what their intentions are, it activates areas in the brain, the control social behavior, even baby see guy contact. we find it harder to lie or sit while looking someone in the yard. we find glances of up to 5 seconds pleasant any more than that can feel intrusive and intimidating. still,

we're going to spend the next 26 minutes looking deep into our eyes. welcome to in good shape the our eyes are constantly active, exploring our surroundings and warning us of dangers. they allow us to see a world that is full of shapes and colors. but producing images that the brain can actually process is not so easy. you need just the right amount of light so that we can recognize weak light sources at night and not be decile during the day, a muscle. the iris regulates how much light enters the eye. when it contracts, the diameter of the pupils is just 2 millimeters. when open in march is to 8 millimeters or the color of the iris is determined by melanin colored pigments that

also determine our skin color. a darker color, iris gives more protection from uv rays, making the i'm less sensitive to light. the next challenge is focusing the only has the lens, a transparent ball of protein that focuses light, reason projects them onto the original facility or a muscles can stretch or curve the lens allowing it to focus on different distances . the more concentrated the rays are when they hit the retina, the sharper the image, the yellow dot shows where the density of light sensitive receptor cells is highest . that's where our vision is sharpest. but please, receptors very, the run cells are especially sensitive to light. then there are 3 different types of cone cells. some codes react to light in the blue spectrum, others and the green or red spectrum. the optic nerves transmits impulses from over

a 100000000 of these receptors to the brain. when things move fast, it's too much for the brain. this is why the eyes are good, rotating in all directions so they can track moving objects. debris receives images from both sides at once. then it goes to work with the information the visual center at the back of the brain turns the countless pieces of information into a colorful 3 dimensional world. dulac remote glands constantly lubricate our eyes with tears fluid. so they can move easily. they wash out for an particles too. and our tears also allow the eyes to express our emotions. the highest of our earliest predecessors could only distinguish between light and dark. some species of jelly fish. i've had these types of sensory sales for 500000000 years. most predators

have forward facing ons. this allows them to see very clearly which is vital for identifying and tracking pray. a birds of prey have real, super eyes was kind of built in binoculars. with a supervisor, they can see a mouse from up to 500 meters away. horses have their eyes on the sides of their heads. this means they can look behind them to detect any possible threats. most species and we humans to have 2 eyes. this allows us to perceive depth, estimate distances, and navigate our surroundings, but to work properly. both sides must be precisely aligned, miss alignments are called stripe isthmus or cross dies. luca loves playing so can, but often he contel legible, is coming from the 10 year old, has strep business as a way to have problems playing soccer. i'm not as accurate as other children. can

be monica. now with your business, your eyes don't look in the same direction. lucas, mother, i noticed early on that something was wrong. this year, the son, when he was 3 or 4, i started to notice that is i would slip when he was tired and perfect. then during an examination at school, they found he had no special visual. i'm just seeing how good spatial vision helps us navigate all surroundings and perceive that this allows us to gauge distance is correctly a person we step business husband paid visual motor skills of lucas dumped to explain why she didn't come to tribe as much as when one i even gates on the normal visual access of so that the image perceived by the right and left died can be fuse together. and con, there are 2 basic types of strep is most competent on power. let's take like luca, most children of the can commenting form here the misaligned i follows the healthy

i with the angle of deviation remaining constant. probably let's extra business is caused by enough distorted the power lies is the muscles she didn't con. uh, because drug this must, can cause problems that affect your students, academic performance industry, for example, and inability to read what's on the blackboard at the school of the tour and reading ability and general restore double vision isn't straining of the net. this was headaches and i, parent has don't coefficient as an organization, as the exact cause is a step, is most and children are not known. certain factors make it more likely to occur, such as having strep business and the family present to this, or lack of oxygen during this. as a rooftop is most must be treated to restore full vision. one treatment option is glosses luca wisdom to correct the misalignment and help him see back to the 2nd treatment option is a pollution. this involves covering the healthy i for a few hours a day in order to train the misaligned i snare for it's

a bit annoying. i don't just have my normal problem. i'm trying to, if it was worse than normal. it also affects me when i'm reading subsidize. if these treatments stay produced, sufficient improvement by the age of 12, an operation can be performed on the muscles to correct the position to feeling. it's a low risk routine procedure that takes around 30 minutes. luca could also have an operation once he turns 12, then his to a business will probably become a thing of capacity. she didn't, this complete tiidwell struck as long as it's completely curable, but it depends on when it gets diagnosed and when treatment again, this is dr. as most it's diagnosed early and treated or latency and the chances of success are good. but if it's diagnosed, delayed, or treated delayed and the chances of success are not optimal, then do you have folders all the sessions, guns ultima, blue cove will never be

a pilot or a bus driver. but almost all of the tools are open to him. he says his greatest wish is to one day become a scientist. it's sometimes said that your preference for a certain high color says something about your personality. people who like blue eyes are supposedly kind and enjoy helping others. those who prefer green or set to stand up for others. friends of brown are thought to be very sensitive. there's clearly no scientific basis for ideas like this, but when it comes to our ours, there are many nets and legend a follow. whereas if you're a dollar g, claim that the iris provide insights into our entire body from the loans and stomach to heart disease is

the escape touch safety. there are small number of illnesses that can be seen in the iris and, but they're mostly inflammatory diseases of the audience, which then involved brand new, almost our deposit or other changing the upside of them in the systemic diseases that you are doubters. claim to see can definitely not go detected where come a definitive needs to can which theories about the eyes are true then we asked people from a variety of countries. my parents always told me not to play video games is video games could cause my prescription to go higher. i've sat and stop. so these 2 guys come now i know that you shouldn't play computer games too much, even though don't stare at screens too much because that's going to be the kind of make use or visit haven't. i've always wondered why display screens are bad for your eyes. you must know how to, for the organs in this, looking at a screen,

damage your eyes. these are the concern that was that the blue waves, things component of light could be harmful to our retina. but fortunately, these problems only arise at a far higher level of exposure, so we won't have to wear blue protecting glasses, a blau shorts. but in, i'll see in the offline beach i'm looking at a screen means looking the same direction and from the same distance for a long time. if it's an all, we also know from studies that some linking frequency is lower, authorized write out more easily. the noise and that can cause problems such as i 15 dry eyes and burning eyes on them. you don't talk miss all depend on or it doesn't usually caused long term damage and you can prevent that feeling of dryness with regular breaks. the best place is outside where the air is more humid . the simplest option is to just close your eyes for a short time. and what about this classic?

it's unhealthy to read in. in dark places, mind them will to my mother, read books under the covers with a flashlight, isn't as it made me miss on. and that's why she has problems. now he can have the it's for blame. it is reading in the dark bad for the eyes. that's just, it's not fond of the subjects, but it can be a strain on your eyes into the old been advised ellipse when something is bright and the contrast is good and it's easier to say my, if you're reading under the covers important dimmed light by 4 or you're really focusing your eyes, then you have to exert them more. it all said that most more that you may understand screens and dark lighting are a strain but not harmful in the case of children. however, that is not the case. that's the intent even now, but when the intensive close proximity to me is i, whether it's with books or computers can be to the young. i'd be coming more near sided at school. age was booked us this. you'll not all get into the door stack.

there was very clear evidence that when children are outside and work during school research, this contributes to their eyes developing healthily and becoming less new side. august the all isn't going to be any got with each, but this vitamin a rich vegetable is said to be really good for our nice site, carrots. i love drinking carrots you sold as though because of the effect of always her the do you think carrots and blueberries are gonna help the the see brother in the dark places i was eating a lot of carrots when i was a child because my, our sites was read, my mom said the terrace, of course, so as they can dig, i think carrots are very important for eyes. but i don't know why those are carrots . good for the eyes, is which i mean i broke the body needs the vitamin to produce visual pigment. the for this pigment helps the sensory cells to detect light was saying,

this device and you want vinzini. and if you don't consume enough vitamin a much to be due to amount nutrition or to certain intestinal diseases, all christian ben at some point on your eyesight might actually be impaired again this month. the 1st sign of this i'm use night blindness or substitution to mix with. i'm not gonna talk is got, i'm a, there was this woman who said her husband, 2 kilograms of carrots every day. he had a toxic reaction to so here to normal, healthy nutrition is advisable. you, that you don't need to eat excessive amounts. i'm almost yes, mission exist, even doors and die couplets. one possible reason behind the persistence of this belief dates back to the 2nd world war. the british didn't want the germans to know that they had invented radar. they prefer to suggest that their pilots, a lot of carrots, which explain their accuracy in the air. over in colombia,

this fruit here is said to have special properties says that the you put lemon use in your eyes to young like babies. then your eyes will be like blue or green. ouch . as will be this in the way. we now know that i color is primary term by genetics and you need to conduct one to practice that, oh, you can't turn eyes blue that way. you have eyes done with my eyes or guns because it's just to miss that doesn't stand up to any scientific screwed. i mean this chapter we focused on so for healthy eyes, take regular, breaks from screen time, get enough daylight, and need a balanced diet. the being far sighted as a very common eye problems. far sighted people can see well in the distance, but images up close or blurred this off and gets worse with age. with short

sightedness, it's the opposite. everything is fine up close, but distance vision is blurred. a problem, it's increasing worldwide, especially among children and young people experts playing prolonged, staring at screens. however, it's short sighted and this is often congenital classes or the simplest solution or contact lenses. then there are so called or so kara tal a g lenses. when we go to mazda, missing some dental on auto sales woman, is that the opticians to get his lenses checked loan by their ortho care ecology or ortho caitlin? since the 18 year old has been wearing them for 2 years. how can i wear them? almost every night now, um, usually for about 6 or 7 hours, it's worth the rate. i was continued off in size of the lenses are only worn at night. the exert pressure on the corneo at precisely calculated points. this

changes the refraction of light and compensating for short sightedness and stigmatism, at least for a number of hours. the effect for you i assigned the idea is that you train away your poor eyesight in your sleep, so to speak. plenty of rick's list and it works. that's off the mileage of stuff to nick, the super, the autopay lenses give you full vision as if you were wearing glasses. so in that respect they work perfectly function in a cell phone. the consistent carpentry can wound up a focus on the number of people who are short sighted is increasing, broken, and they want pushed into contact. then you can correct it by using contact lenses or glasses, or even decor by using both ok. lenses which also remedies shortsightedness, a consistent guide, but you have to start at a young age when most of the things and you, when you're ideally, um, usually stuck between the ages of $6.10 or 12, and then continue it and sell them at the beginning because it has to happen during the growth phase to slow down this development. and that's my thought is that and

take that plus, i'll spell that. but you don't get sharp vision right after the 1st night. i must 1st adapt to the lens. this is a relatively long adjustment phase. it doesn't work after just a day or 2 close it. and the onset harden dismissal continued as posted. it takes days and sometimes weeks to reach the target refraction. and to get the corneas shaped in such a way that it works well every day talk, it's during the transition phase does the work of daylight disposable lenses. so it's investment target citizen that proponents say it's worth the extra effort for the benefits it brings up in full in. but they were recommended to me because my eyesight isn't that bad. and i met the requirements. i were normal lenses before i was told there. good, if you do a lot of swimming, for example, because you could lose normal lenses in the water would not be worth okay. lenses again about to do also kaiden's missed the lenses aren't suitable for everyone. so

many quotes, it's a crime, it really for short sighted people to a political existence kindly. it works very well for prescriptions of up to minus 4 and a half diameters maxima, sum astigmatism can also be treated with, but only certain prescriptions. after that, you reached the limit of what is feasible this ma bob. and there are a few disadvantages. those 3 different and the change in the front surface of the cornea and then the coordinator will cells themselves, which means your contrast sensitivity decreases slightly at night when driving you proceed color slightly differently to the so you should expect to see less well at night. then you would with glasses or smoke, if you have a cold, severe fever or similar symptoms, you shouldn't wear the lenses at night to use it afterwards. you then have to go through the adjustment process again to route it over the course of the day. the cornea starts to return to its normal shape, so your vision deteriorates in the evening of veiling or be send mail. we respond

to that by over compensating of somebody if the prescription is 3 di options. for example, we would correct 3.75 di options for the morning problem and is these are mostly young people and they don't notice any difference. and even though their eyesight deteriorates, during the day, we're hopefully still achieving a correction of the desired 3 di options. in the evening, i think of interesting part of the old play. the downside is that the lenders are expensive and you need once, once a year is tied into and see if it's time consuming and requires planning a visit to the petition. it's high tech and unfortunately it's also expensive on the top of the but if you stick with it, it can be great. i think you have a lot of freedom. i don't need to wear lenses during the day and demonstrate to others. i agree that i find it really practical for sports in general. like you don't have to wear glasses or lenses at all, then you just wear them at night and then everything is fine for the rest of the day. i was concerned about some progress with minds about

fines technology that's like dw signs is now on take time. what do you do for fun? why do gravitational ways that that is when did people begin getting high and laughing gas out? the drums boogie to the beads and what's the pass that the kids football find the on says gets most c w science. oh, new tick, tock channel. ringback have you ever heard of office i syndrome or a game or i the comes from looking at a screen constantly which is very stressful for your eyes. they may take or sting. your vision can be effected for your eyes can be sensitive to light. the most common consequence is dry eyes. if you look intensely at your computer or cellphone, you don't blink is off. so your eyes are no longer capped and lubricated with tears

. but dry eyes are not only caused by staring at a screen at an optician store invalid. the customer is having an ice tested to see if that to dry by my so blink twice and again. now, leave your eyes open using a cavity graph. the opposition can find out where the each eye is sufficiently supplied with fluid to be able to wear contact lenses. for example, the up hopefully moment. do you know anyone who has problems with their eyes? oh, stinking red in the eyes to very tired eyes from you should get themselves to consort the, to the missile, the so called my bone me in glands show up especially well on the screen. these plans are located in the lower end of the i'm, it's basically oil which coats the surface of the ice. this is even i zone. you see these little white lines. they are the my bone, me implants,

they secrete this lip, it which stopped the tier film from drawing out. there was previously a story on the island here, the sty, his healed, but it's destroyed to my bone, me and glanced on what seemed to buy fun, didn't. my appointment was attached to that. people who were contact lenses are especially printing to try ice. the lens isn't often warned for too long or not to clean properly. the recommendation here is to alternate between glosses and lenses, all with disposable lenses. the co, it's a graph test only takes a few minutes then be it's not if there is no progress or improvement, then we tell the customer to see an opthamologist that naturally or even try to open up dr. bob of a judge often has patients who complain of dry, stinging o itchy eyes. get to the examination is very simple. to aid the process,

the patient is given, eye drops, all this makes it easier to see the teeth. so, and any injuries using blue light or receive mail or i'm seeing more people with dry eyes now and more people with dice caused by their dry eyes. i'm also seeing people who are struggling to work at a computer issue is not, and they think their glasses aren't strong enough. what is actually just their dry ice and the $34.00 or 5 extra hours of work on the pc right on p. c. so most people, the problem can be solved with lubricating eye drops, experts recommend drops without preservatives. they can be applied repeatedly as required, but this doesn't solve the problem for everyone. for those who still need help, the ophthalmologist recommends pump tool plugs. these tiny, silicon pugs close, the duct to stop t is draining away. the smoke load is inserted,

painlessly into the 2 duct. the i then has more at the bodies and t of fluid available here. now, 80 percent of the chair of fluid drains hears to 2020 percent in the upper area. so there's still enough capacity for the rest of the picture. so at the drain here, do you guys clean for this is caught here, optimized, there, puts in not the patient doesn't noticed, apply to the, disappears into this little channel advice. you can just see a white dog, but it doesn't bother the patient to intrude sickness. because good. another problem is that many people with the wrong glasses for watching that a computer. they will have very photos with progressive lenses. the field of vision where objects that a medium distance a p, a shop is very narrow. so you can see the entire screen at once, computer glosses with close up comfort, then this would help. the field of vision here is significant. b, y to, to compare once again the view is very photos. people who use these losses. the computer will often develop a pool post. you don't, it says when it's on

a fits you struggle to read your computer screen. so you try to look through the close up area at your glasses and get closer overtime to strains your neck with computer glasses that close up range is incorporated into the upper part of the glasses. so you see comfortably and only have a slight restriction of your middle distance collisions. the incidents, the makeup, especially i line of applied to the in i need can clock the my bow, me in glands making your eyes strongly. there were numerous cab products available for dry ice in the form of drops or sprays. so choose computer glasses. i that that recycles, use lubricating adults. and one also helps is to consciously blink more often. the 3 simple meshes that can help keep your eyes moist, uncomfortable, that we often close our eyes at crucial moments like when kissing

or save a ring and experience. sometimes even during sex, why do we do that? requires that norm is brain power. when we close our eyes, we can focus much better on stimuli from our other senses. like hearing feeling, we're tasting. give it a try, but don't forget to keep your eyes open for the next edition of in good shape. see you next week. the
