TOP 10 THINGS WE DIDNOT KNOW ABOUT OUR EYES-FORWARD .
Without our 5 senses life would be pretty dull. All oursenses are extremely important but I think if you asked most people which sense would they least like to lose they wouldprobably say their vision. As with most of our abilities, our visionis something that many of us take for granted. If you stop andthink for a moment, you would realizethat just about everything we do in ourday to day life involves our vision. Inthis article I am going to try and see if I can get you to start thinking a little bit more about your eyes. Listed below is mytop 10 list of weird and wonderful things you did not know about your eyes 10. Everyone needsreading glasses as they get older This is assuming that you already have perfect distancevision. If you are currently readingthis article and are under 40 years of age with perfect distance vision, I can say with absolute certainty that youwill need reading glasses at some point in the future. For about99% of the population the age that you will first start needing reading glasses is between 43 and 50 years old. This isbecause the lens in your eye slowly loses its focusing ability with age. In order to focus things near to you, your lens has tochange from a flat to a more spherical shape and it loses theability to do this as you get older. As you get to around 45 years old you will start to holdthings further away from you to keepthem focus. 9. The lens in your eyeis quicker than any camera lens Just behind the pupil sits the eyes natural lens, whosefunction is to focus on the object you are looking at. Just take aminute to glance around the room and think about how many different distances you are focusing at. Every time you do this, the lens in your eye is instantly changingfocus without you even being aware of it! Compare that with a camera lens which takes a few secondsto focus between one distance and another. Just be thankfulthat the lens in your eye is as quick as it is, otherwise things would be continually going in and out of focus. 8. Your eyes are fullydeveloped by the age of 7 years old By the age of 7 years old our eyes are fully developed andare physiologically the same as adults eyes. It is for this reason that it isvitally important to pick up a lazy eye before we reach this age. The earlier a lazy eye is diagnosed, the greater the chanceit would respond to treatment, as the eyes are still developingand capable of an improvement in vision. Beyond 7 years old no amount of treatment willresult in any improvement in vision. My note- With moderntechnology it is possible to treat eye vision at any age with contact lens etc. 7. You blinkapproximately 15,000 times each day Blinking is a semi- involuntary function meaning we do itautomatically, but can also choose to blink if we so require. Blinking is an extremelyimportant function of your eyes as it helps remove any debris on the surfaceof your eye, byspreading fresh tears over them. These tears help to nourish your eyes withoxygen and also have important antibacterial properties. You can think of the function of blinking as beingsimilar to the action of the windscreen wipers on your car, cleaning and removing everything tokeep you seeing clearly. 6. Everyone gets cataracts as theyget older Peopledon’t realize that cataracts are just a normal consequence of getting older and everyone gets them at some point in their life. You can think ofcataracts as being similar to getting grey hair, in that it is just a normalnatural age change. Theaverage age people first get cataracts is about aged 70 years old and by 80 years old you are guaranteed to have cataracts. In the same way that you could not find any aged 80 yearsold without grey hair, it would be equally impossible to findanyone over 80 years old without cataracts. Cataracts refer to a gradual clouding of the lens in youreye and typically take about ten yearsfrom onset to them needing treatment. My note- Now cataract comesto people by 60-62 years because of viewing TV channels etc or an evolutionarychange 5. Diabetes is oftenfirst detected during an eye test People who suffer from type 2 diabetes (the type youdevelop later in life) are oftensymptom free, meaning they often don’t even know that they have it. This type of diabetes is commonly picked up during an eyetest as it can be seen as tinyhemorrhages from leaking blood vessels at the back of your eye. This certainly is good reason to get youreyes tested regularly. 4. You see with yourbrain and not your eyes - The function of your eyes is to collect all therequired information about the object you are looking at. This information is thenpassed from your eye to the brain via the optic nerve. It is the brain(visual cortex) where all this information is analyzed to enable you to see the object in its finished form. This is not to say that youreyes don’t play an important role as they certainly do. My note- if at all brainis perfect with out eye information cannotbe passed. So it is equally important. 3. Your eyes can adaptto blind spots in your vision Certain eye conditions such as Glaucoma and certain generalhealth conditions such as having a stroke, can lead to youdeveloping blind spots in your vision. This would be extremely debilitating if it was for your brainand your eyes ability to adapt to make these blind spots disappear. It does this by suppressing the blind spot in your affectedeye and letting your other good eye fill in the gap. It is adaptation like this that makes youreyes so resilient. 2. 20:20 vision is notthe best vision you can have Whenpeople hear the phrase 20:20 vision they assume that this is the best vision possible. However this is not true as 20:20 vision refers to what theaverage adult should be able to see. If you imagine a typical eyetest chart the 20:20 vision is probably only the line second from the bottom. The line below it is even smaller than 20:20 vision andwould mean you have 20:16 vision. So don’t be so impressed next time someonetells you they have 20:20 vision! 1. Your eyes water whenthey are dry I know this might sound crazy but this is one of strangefacts about your eyes. Your tears aremade up of 3 different components and they are water, mucus and fat. If these 3 components are not inexactly the right quantities, your eyes can become dry as a consequence. Your brain responds to this dryness byproducing extra water and hence youreyes water. >From my archieves aposting by Sri "KC Ravi" [email protected] om Wed Nov 24, >2010 is forwarded today 27-3-2021with highlights, spelling correction and >certain remarks. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
