the our eyes are constantly active, exploring our surroundings and warning us of dangerous. 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 dazzled 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 opened in large is 28 millimeters. the color of the iris is determined by melanin colored pigments. the 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 raising projects them onto the wrench. and cecilia, 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 cones react to light and the blue spectrum authors 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. the brain 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. deland criminal glands, constantly lubricate our eyes with tears fluid. so they can move easily. they wash out for and particles too. and our tears also allow the ice 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 ok. 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 super 0, 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 depths, estimate distances, and navigate our surroundings, but to work properly, both sides must be precisely aligned. this alignments are called stripe isthmus or cross dies. luca loves plain, okay, but often he contel legible, is coming from the 10 year old construct business as a way to have problems playing soccer. i'm not as accurate as other children. can be monica, not with strep 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. and then during an examination at school, they found he had no special visual. i'm just seeing how good spatial vision helps us navigate how surroundings and perceive that this allows us to gauge distance is correctly personally, step business has been paid visual motor skills of lucas don't to explain why she didn't come to tribe as much as $11.00. i even gauge on the normal visual access so that the image perceived by the right and left died can be fused together and con. there are 2 basic types of strategies, most competent on power. they take like luca, most children of the good comments and form via the misaligned i follows the healthy i with the envelope deviation, remaining constant. however, it looks like so business is caused by end of distorted the power lies is the

muscles cheating con, uh, because drug this must, can come as problems that affect the students academic performance industries. for example, it's an inability to read what's on the blackboard at school of students who are reading ability in general restore double visions and straining of the necklace with headaches and dietary hospital coefficient as an organization. as the exact close, instruct, based most in children are not known. certain factors make it more likely to occur, such as having strep isn't within the family premier to this, or lack of oxygen during this. as a rules type is, must must be treated to restore full vision. one treatment option is glosses luca with them to correct the misalignment and help him see back to the 2nd treatment option is a collusion. this involves covering the healthy i for a few hours a day in order to train the misaligned on the snare fruits. a bit

annoying. i don't just have my normal problem. i'm going to if it was worse than normal. it also affects me when i'm reading some stuff that i if these treatments they produce sufficient improvement by the age of 12 operation can be performed on the high muscles to correct the position to feeling it's a low risk retain 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 as complete, tiidwell struck as long as it's completely curable, but it depends on when it gets diagnosed. and when treatment again, this is strep, as most is diagnosed early and treated or latency, and the chances of success so good. but if it's diagnosed, delayed, or treated delayed and the chances of success are not optimal, then the other folks always the sions guns, altima, blue cove will never be a pilot or a bus driver. but almost all the other tools are open to him. he says his greatest

wish is to one day become a scientist. it 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 a crane 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 eyes, there are many nets and legend follow . whereas if you're a dollar g claim that the iris provide insights into our entire body from the loans in stomach to heart disease as the keep 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 change and there. and with the upside of them in the systemic diseases that you are doctors to 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 because 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 either for the organs in this looking at a screen, damage your eyes. these are the concern that was that the blue wave length

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 shots, but then i'll see and go into 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 the blinking 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 it doesn't usually caused long term damage and you can prevents 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 a house, it's a 3 in in dark places, mind them will to my mother,

read books under the covers with a flashlight, isn't as it made me move on, and that's why she has problems. now he can have the full blame in his reading in the dark bad for the eyes. that's as it's not sancho the subject, 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 thank you. my. if you're reading under the covers important dimmed light for or you're really focusing your eyes, then you have to exert them more. and i'll should, that much more that you may understand. so 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 added to me, here's ice, whether it's with books or computers can be to the young. i'd be coming more near sided high 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 recess, this contributes to their eyes, developing healthily and becoming less new side. obviously all isn't going to be in new york with each but this vitamin a rich vegetable is said to be really good for our eyesight. carriage. i love drinking carrots you sold as of finish as a perfect of always her the do you think carrots and blueberries? are gonna help the, the see brother in the 3rd 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 health if they can dig. i think carrots are very important for our eyes, but i don't know why our carrots, good for the ice, is which i mean i broke the body needs the vitamin to produce visual pigment. the for this pigment helps this sense resolves to detect lives in the spots in new

orleans vinzini. and if you don't consume enough vitamin a much to be due to mount 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 politeness or is that switch to mixed with on or not been talk? it's got i my there was this woman who said her husband, 2 kilograms of carrots every day. you just see how to toxic reaction to so here to normal, healthy nutrition is advisable. you don't need to eat excessive amounts. i'm almost yes, mission exist even though isn't the top woodson. 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 ate a lot of carrots, which explained their accuracy in the air. over in colombia, this route here is said to have special properties. says that the view put lemon

use in your eyes to young like babies. then your eyes will be like blue or green. ouch. as of the vision. yeah. what we now know that i color is primarily determined by genetics. you need to conduct one to practice. now you can't turn eyes blue that way. you have eyes done with my eyes or guns because it's just a minute. that doesn't stand up to any scientific scrutiny this chapter we focused on. so for healthy eyes, take regular, breaks from screen time, get enough daylight, and eat a balanced diet. the being far sighted is a very common eye problem. far sighted people can see well in the distance, but images up close or blurred this off and gets worse with age. with short sighted as 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 plain, 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 up to him on the rest of the front, on the, on auto sales woman is that the oppositions to get his lenses checked alone by their or so care ecology or ortho k lenses in the 18 year old has been wearing them for 2 years i'm going to try to talk to you. i wear them almost every night now. usually for about 6 or 7 hours, it's worth 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 reflection of light, compensating for short sightedness, and stigmatism,

at least for a number of hours. the effective for you to assign the idea is that you train away your poor eyesight and your sleep. so to speak, and you have a mix left and it works. that's off the mileage of stuff to nick. the else does complete the super, the autopay lenses give you full vision as if you were wearing glasses. so in that respect, they work perfectly confidential from the inconsistency content. we can wind up a focus on the number of people who are short sighted is increasing, broken they want pushed into contact, then you can correct it by using contact lenses or glasses or even to go about using both ok lenses, the which also remedies, shortsightedness. a consistent card, but you have to start at a young age when most of the things and when you're on a daily, usually stuck between the ages of 6 and 10 and 12 and then continue. it begins because it has to happen during the growth phase to slow down this development. and that's my thought is that it takes on it plus i'll spell that incident. but you don't get sharp vision right after the 1st night. i must 1st adapt to the lens is

always a relatively long adjustment. things like it doesn't work after just a day or 2 in the mindset. harden dismissal continued as pulse 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 good from during the transition phase. does we work a day? and i disposable lenses by photography? is that proponents say it's worth the extra effort for the benefits that brings counseling, 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 they're good if you do a lot of swimming, for example, because you could lose normal lenses in the water, but not the work. 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 play gold system because it works very well

for prescriptions of up to minus 4 and a half diameters maxima, some astigmatism can also be treated with, but only certain prescriptions. after that, you reached the limit of what is feasible this ma bob and and there are a few disadvantages. the christopher and the change and the front surface of the cornea and then the coordinate will cells themselves, which means your contrast sensitivity decreases slightly at night when driving. you perceive color slightly differently to the so you should expect to see less well at night. then you would with glasses, or if you have a cold, severe fever or similar symptoms, you shouldn't, where the lens is 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 the veiling or be send me off. we respond to that by over compensating the of somebody. if the prescription is 3 die up to us, for example,

we would correct 3.75 die 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 day options in the evening. i think of interesting, i don't play. the downside is that the lenses are expensive and you need new ones once a year. as a tight in tennessee, it's time consuming and requires plenty of visits to the opposition. it's high tech and unfortunately it's also expensive on the public. but if you stick with it, it can be right now because you have a lot of freedom. i don't need to wear lenses during the day. it's due to me. so as i agree, 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 the mcknight and then everything is fine for the rest of the day. i was concerned about some progress with minds about science and technology. that's why dw science is now on take time

watching fun. why do gravitational ways that that is when the people begin getting high and laughing gas out of the drums boogie to the beads and what's the perfect king footboard find? find the on says gets most dw signs on new, tick tock channel. 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 8 or staying your vision could be effected for your eyes could be sensitive to light. the most common consequence is dry eyes. if you look intensely at your computer or cell phone, you don't blink is off. so your eyes are no longer kept 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 optician can find out where the each eye is sufficiently supplied with fluid to be able to wear contact lenses. for example, just the absolutely 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 consorted . she's a missile. the so called my bone, me in glands show up, especially well on the screen. these plans are located in the lower and upper and it's basically oil which copes the surface of the ice here as well. you see these little white lines. there are the my bone, me implants, they secrete this lifted,

which stops the tier film from drawing out. there was previously a sty on the island here, the sty, his healed, but it's destroyed to have my bill. me in the wireless. one hutch seemed to buy a fundraising life when it was attached to that. people who with contact lenses are especially prone to try ice. the lens isn't often worn for too long or not clean properly. the recommendation here is to alternate between glosses and lenses full 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 to feed and touch them overnight . dr. bava yeah, much 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. and they think their glasses aren't strong enough when it's actually just their dry eyes and the $34.00 or 5 extra hours of work on the pc right on pc. 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 tier duct. the i then has more at the bodies and t and fluid

available here. now 80 percent of the chair of fluid drains, here's 2020 percent in the upper area does high. so there's still enough capacity for the rest of the chair, so it's a drain here. do you guys clean, please? he's caught here. optimized, there, puts in not the patient doesn't notice the planet 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 confidence. this would help. the field of vision here is significant the wida to compare once again, the view is very cycles. people who use these losses for computer work often develop pull post you dollars because when you're on a piece you struggle to read your computer screen. so you try to look through the

close up area, it's your classes and get closer. over time the strains are neck, but 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 glosses that recycles, use lubricating adults, and what 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
