it becomes the scene of a horrible tragedy. arab terrorists, armed with sub machine guns, went to the headquarters of the israeli team, and immediately killed one man. and that this will be the last one was so in life or worse, fears realized my. they're all gone. how i witnesses experienced the terrible events and this, the world should not forget the low shuttle, the 1972 olympic massacre. start september 3rd on d w. our eyes are often called the windows to the song. when we feel connected to someone, we look deep into their eyes. they can supposedly also help us tell if someone is being honest with us in this episode of in good shape. we'll explore the world of

optic health and separate fact from fiction. and how about lesson no methods will keeping our eyes healthy. welcome to in good shape. ah ah, who ever wanted to take a deep look into your own eyes? you can at this berlin photo studio using a picture of your iris. i know there's so much more to it than what you see it 1st with fascinating counter like looking into your own. so in the video. but some people also believe you can see much more in the color and structure of the iris. we're going to take a closer look at this and related theories.

oh, followers of irig. ology claim that the iris provides insights into our entire body from the lungs and stomach to heart diseases ah, is skipped. i'd say, hey, there are small number of illnesses that can be seen in the iris, but they're mostly inflammatory diseases of the eyes, which then involve granular, almost our deposit or other change there would abdougla. and i though systemic diseases that erode doubters the claim to see can definitely not go detected there . come and if any teeth nice deck hand. oh, 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 and i've sadness stop. so if you i

just gum now i know that you shouldn't play computer games too much. she didn't. oh, don't say it's there screens too much, cuz that's going to be, that's gonna make you. this is an image. i've always wondered why display screens are bad for your eyes image out of for the organs and they're looking at a screen. damage your eyes these aug of the concern was that the blue wavelengths component of light could be harmful to our retina. but fortunately, these problems only arise at a far higher level of exposure. you may show we won't have to wear blue protected glasses allow shorts, but then i've seen going longer offline beach and looking at a screen means looking the same direction and from the same distance for a long time. this is all we also know from studies that the blinking frequency is lower than all her eyes dry out more easily. lena is, and that can cause problems such as i 15 by eyes and burning eyes on them. you don't miss all the been the old. oh,

it doesn't usually cause long term damage and you can prevent the 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 a health, it's is it in, in dark places, mine and water. my mother read books under the cover is with a flashlight, isn't as a mid ms on, and that's why she has problems. now he again had the, it's probably made his reading in the dark bad for the eyes. thus it's, it's not harmful as such, but it can be a strain on your eyes and truly all been. it was hairless when something is bright and the contrast is good. and it's easier to see thicker bodies, my, if you're reading under the covers him when dimmed light i from are you really focusing your eyes? then you have to exert them more. i mean, all should than most margin to manage things. so screens and dark lighting are

a strain but not harmful in the case of children, however, that is not the case. thus d intense even now by it when the intensive close proximity i to with i, whether it's with books or computers, can lead to the young. i becoming more nearsighted at school age. so i was booked thus. thus, younger algorithm should either doc stack, there is very clear evidence that when children are outside work during school recess and this contributes to their eyes developing healthily and becoming less nearsighted. august all isn't advocate on vinegar equity. ah, this vitamin a rich vegetable is said to be really good for our eyesight. carrot, i love drinking carrots, you sold his off, finish as a perfect of always her dad. ethan keratin blueberries, are gonna help her to see better in the dark places. i was eating a lot of carrots when i was a child because my r was, as my mom said, that caris,

of course hell is taken thick. i think carrots are very important for eyes, but i don't know why our carrots, good for the eyes, is which i mean i broke the body needs the vitamin to produce visual pigment. the fox is pigment helps the sensory cells to detect liason, least watson. you wouldn't vinzini and if you don't consume enough vitamin a, but it could be due to malnutrition or to certain intestinal diseases. mr. ben, at some point on your eyesight might actually be impaired. hacienda martin, the 1st sign of this one is night blindness. orsowitz ish soon mixed with on or not as gap. i my there was this woman who fed her husband 2 kilograms of carrots every day. he had a toxic reaction to him. so here to normal, healthy nutrition is advisable that you don't need to eat excessive amounts. i'm almost yes, nice excess. even doors and ha ha, puts 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 aid 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 juice in your eyes to young leg babies, then your eyes will be like a blue or green. ouch. as would be this. and ya. what we now know that i color is primarily termed by genetics. we need to hinder clinical practice, though you can't turn eyes blue that way we have i done with my eyes guns closet. it's just a myth that doesn't stand up to any scientific scrutiny. this is jackie here. we focused on. ringback ah, so for healthy eyes, take regular breaks from screen time, get enough daylight, and eat a balanced diet. ah,

places like these are used for a wide variety of purposes. we most likely to see them at light shows or at supermarket cash registers will scanning bar codes. but thumb lays is not strong enough to cut through metal. others are used to medical procedures like skin re termination and lasers can also be deploy to improve people's vision. so they no longer need to wear glasses. uninsured angel is passionate about tennis. she's played since she was a child, and she's also warned classes since elementary school to help with her nearsightedness. but they're less than ideal for tennis with tennis, her skin, i love playing tennis, but wearing glasses when i play in the annoying, they're always sliding down when i run and they get dirty and rained on. plus,

i always have to worry about a ball hitting me in the face, cuz i can't do the 26 year old student were contacts for a long time, but she suffered from dry eyes and conjunctive ideas and couldn't stand them anymore. that's when she decided to undergo laser eye surgery. this procedure is used to correct vision disorders and is usually performed on healthy eyes. it's not medically necessary. how safe and effective is it? before the surgery, there's an extensive preliminary examination to find out whether or not honest styles eyes are healthy enough to endure the surgery. her vision, retina, and pupils are carefully measured. the shape and thickness of the cornea is also very important. as this is the part that will be altered by the laser, interest of you to halt. if one of kind of fight is or not, we definitely want to avoid making the cornea to said is equal with another risk is

infection. and the 3rd risk is that it will have to be corrected again, or this doesn't have into them. those are the main risks, how closing to the home and for understand those eyes are healthy and or cornea is thick enough for the procedure. naturally, huffman respectful, of course, i operations come with risks, but i think everything will be under control. and i just can't wait for that moment when i can see without glasses. thinking dennis, her laser surgery is booked for a few days time. we'll find out later how it went. oh, zara flare from lans back is also near sighted. she's. ready about to have ice or drink at the munich university hospital. i want to be a police officer, so i need better vision to pass the entry requirements. i'm a bit nervous at the moment, but i'm okay. it is, i'm a flare is only 18 years old. but laser eye surgery is legal that this young age of

is the 2nd of it. there are downsides to having the surgery. so young is always because the i changes throughout our lives, it continues growing for quite a long time, and the length of the eyeball changes which can worse than nearsightedness. but if there are changes, we have enough tissue as a buffer for follow up treatment. on the one off of the other, professor myer uses the smile method on solar flares, numbed i thence when the laser cuts a small linds shape piece of tissue called the lenti q. within the cornea, professor meyer then removes the lent a que via small incision in the cornea, and correct sir nearsightedness in the process. the surgery only lasts a few minutes and it went well. cool, there's a strange feeling in my eye, but it's not so bad. it's definitely a lot better than a trip to the dentist. when problems occur, they usually appear directly after the procedure. this includes light sensitivity and dry eyes. this more slow,

we need to identify problems right away and treat them as required. we can administer eyedrops as tear substitutes. the entire process lasts 2 to 3 weeks. longer of necessarily corrective eye surgery is expensive. the costs vary between a few 100 to a few 1000 euros. post operative care is very important as well. 40 year old ellen tok has come in for a post op check up the laser surgery on her eyes was performed by professor daniel cope. he used the logic method, which involves cutting into the very front layer of the cornea. the surgeon creates a flap and opens it like a lid. then a 2nd. glaser re shapes the cornea underneath the flap. finally, the flap is closed again and sealed in place. it's been 6 weeks since ellen's procedure blue. i hadn't done. i never felt any discomfort, like there was something in my eye or that my eyes were dry right from the

beginning. it was a perfect result. thinking. laser procedures have been around for decades with constant advances in technology. long term studies on the logic method have revealed that more than 95 percent of patients who undergo the procedure are satisfied. but there's no guarantee of a lifetime of good vision. you'd have men's couldn't middle age. every one start to develop press be opiates assist with the eyes, gradually lose their ability to focus on nearby objects. that's when people start to need reading glasses. laser surgery can't prevent that is a font that to tennis player honest tango. her surgery went well to doctor vine of id fung, used the smile method for her laser eye surgery. the entire procedure took less than 15 minutes. that's isn't her sierra finished. often the small incision is still open, which means she won't be able to drive for the next few hours. but when she gets home and rests her eyes for a bit,

you all know she'll notice that she feels better with each passing hours. but from from that stronger vessels to connect us is me at was splendid. and i am experiencing a bit of glare other than that, a slightly milky hazed, but it's already a lot better with no glasses. and the entire operation was so fast, it's crazy for bias. as a swanson ana gets picked up by her sister in a few days, her vision will stabilize the decision to get laser eye surgery is a very personal one. what's crucial for all patients is being able to make an informed choice. and now we'll take a glimpse into the future of medicine. many people only know see lead as a tasty side dish. research has, however, believe that the plant has a wealth of medicinal potential. seaweed has been used in traditional medicine for centuries. it's healing benefits already being researched on animals as an alternative antibiotic and for healing wounds. can see we'd also help our eyes

the waters of germany's baltic sea coast, our home to some real treasures of the natural variety. there are 1800 different species of brown algae. one of them grows on strings right here on the seaweed farm run by inez lanka and her team to the marine. biologist believes in the huge potential of sugar help or in latin sac arina. letizia not as i ask them to see weeds are so fascinating because they really are the oldest plants in the world . you have to think about the time scale and how they've been able to adapt to underwater habitats and sometimes to the shore zone. to unpack the sheer diversity of natural active substances involved is amazing. ok. whose seaweeds are rich, minerals, vitamins and fiber, which is why they're considered a healthy food option. japan is a country with

a high consumption of seaweed and also one with a long life expectancy. could there be a connection? oh, does see we'd have more uses than just holding rice together. might even strengthen our immune system. exactly how beneficial seaweed is to our health has not yet been comprehensively studied. but scientist likes is on the album, are convinced. seaweed contains a treasure trove of medicinal compounds. de paula and titan, whose brown algae contains certain polysaccharides or long chain sugar molecules, which boast a particularly large number of biological activities. and that's very exciting for potential pharmaceutical use in the long term. a traditional physician living together with biologist, alexa ledner and her team, susanna,

album is conducting research on those long chain sugar molecules from the cell walls of the algae, so called few coins are found in varying concentrations and compositions in all brown algae. and they can evidently stop a common aggressive eye disease known as age related macular degeneration. the condition is caused by damage to the macula, the point of sharpest vision on the retina. abnormal new blood vessels develop under the retina, driven by special growth factors. the vessels rupture burst and leak fluid or blood causing damage to visual cells, which then die. the results is blurry, vision, or even blindness. the i just, there are different manifestations of age related macular degeneration in the worst kind, the wet variety, a growth factor called v g. f plays a role. and what we were able to show very early on is that some food coins can actually inhibit the e g avenue chron. but which for coins from which algy can best prevent this

pathological growth. a question the researchers want to answer that for coins also have another positive property. they apparently protect cells from oxidative stress . in the i oxidative stress is caused by exposure to light uv. radiation is considered a major cause of age related macular degeneration. laboratory tests have shown the adding for quite ins. gifts i cells, it improves capacity for surviving oxidative stress, city moving against on what i really hope is that the food coins will enable us to develop something that can be administered much earlier when the patients are still asymptomatic us yet we ophthalmologists might already see that there's a problem even if the patient doesn't notice it yet. if we could introduce who coins at that moment and we might be able to prevent vision loss happening at all. that's our dream. which is why for coins are being systematically studied. the long

chain sugar molecules come in a wide variety. even the process used to extract them from the seaweed has an effect on their chemical structure, as does the time at which they are harvested and the see they grow in size diagnosed after high solidity nutrient content, u, v. exposure, title range, and wave height. all of these factors have an impact on the food coit in content. and as such, the quality of the few quite in this will go down spine. the quality of the active ingredient has to be consistent if the seaweeds are to be used to make medicines. so there's still plenty of work ahead for the scientists when it comes to harvesting the full potential of these very special plants. ah, do you have a question then write to us whether it's about nutrition, exercise research,

or therapy in good shape. we'll ask the experts just send us an email and the digital consultation can begin. dry eyes are a common problem worldwide. studies show that in this era of lock downs and an increase in work related screen time, the problem has gotten even worse. make sure to take breaks regularly and to stay hydrated. but if your eyes are read for prolonged periods or if they heard head to europe, tamitra st. want to get rid of those unsightly red eyes. no problem on a computer at least. but it's not always that easy. this ophthalmologists practices, patients on a daily basis complaining of genuine red eyes among the possible causes a boost blood vessel in the conjunct title membrane at the front of the eye,

leading to a tiny hemorrhage on the surface. what often looks alarming is in fact, in most cases harmless madison button that manages act. most patients have a fairly mundane reason for a red eye. it might be anything from a dry eye to a foreign body or a perfectly harmless sub conjunct table hemorrhage. these kinds of things account for most red eyes by the way to deal. now. it was a foreign object that prompted alexander yackel to see the doctor today. he's an organ maker and had a work related accident. megan, i was using a handheld circular saw to cut a plank of wood. and as i was looking down at the saw, a chip flew straight into my eye pretty straight forward, but it really hurts. social clothing from the doctor removes the tiny splinter with a cotton wool bud and checks for signs of damage to the cornea. after giving the patient eyedrops, she applies blue light to reveal any injuries. oh, fortunately,

alec sunday. yeah, cobb is unscathed from the incident. then you don't wear goggles, no, right when the chip started flying, i remember thinking it would be a good idea to put them on, but it was too late. the doctor's next patient is here for a follow up check. she also had another typical injury. this time, not from a foreign object, but a self inflicted wound. the redness in her eye has since faded. first comes home with us, it's been up, go to my fingers, sledge, i'm really not sure what happened. and then i felt a stab in my, i lost them popping off what you get this quite a what when people are doing their make up. for example, in another frequent one is parents are playing or coddling with their young children and end up with a finger in there. i. it's all the problem. minor injuries to the cornea, usually he'll on her own within 24 hours with more serious injuries. the patient should be given, antibiotic eye drops in order to prevent an infection another harmless,

but still painful, affliction or style, which are caused by a bacterial infection of the eyelash follicle or eyelid gland. the surrounding skin becomes red and swollen. d o nude yvonne who my eyelids were red and you could see a little lump and it scratched terribly on my eye and it still does, does as i didn't look before her style can be treated with a special ointment and they normally go away without any complications, but you should see a doctor if you are. i remains red and you have symptoms such as itching a burning sensation pain or a sensitivity to light. in these cases, the cause may be more serious, red eyes or a very common symptom, but household remedies like camomile t should be used with caution. the common english one and on the wharton patients come in with a swollen red eye and tell me what they've tried. and i think, okay, they've tried a cam, a mile tea bag keyboard, but that can often cause allergic reaction. so it's better to avoid that option.

vitamin best, honest mom. so remember to keep camomile tea bags where they belong in a cup of hot water. and now it's your turn. take out that work out mass because his personal trainer. okay, yeah, with a new exercise. hello, all you need is to day a met and a wait. we do turkish get up. where is this name from turkish wrestlers they 200 years ago. the same exercise to show us how strong they are. and we do today exactly the same for this exercise. you need to wait. i take today what about what you can take, whatever you want to spend your leg straighten you are bring the

other hand to the side and then sit up. wait is on your hand. heaps. hi. bring the straight leg backwards on to your knee. then stand up and we go back down again in through a lunch. bring the weight on your hand. bring the leg forward. sit down fully controlled, straight from the leg. try to accumulate 6 rips, meaning 3 reps on every side, but you chain after each other. so you do one side. when you have finished exercise to change. decide. i love this exercise because you need to be fully concentrated. this means you're being in the here and now with this exercise, you train your full body,

you train your legs, you train your arms and you train your mid line to stand up and then you go back down again with time to get up and go. let's all for today. see you next time on in good shape dw health program. with

jillions journey around the world, starting september 7th on d. w. ah . there's a dw news line from berlin, russia shoot down a drone over the headquarters of its black sea fleeting for me. it's the latest attack targeting russian military infrastructure on the and explaining to one and a bloody siege and somali, the somalian capital mogadishu comes to an end. the attack leaves at least a dozen dead.
