Adam Ruins Everything – Does TV Destroy Your Eyesight? (Ask Adam) | truTV


♪♪ Our viewer James asks,
“Does watching too much TV really destroy your eyesight?” Come on. We stare at screens
24 hours a day now. If looking at them actually
destroyed our eyesight, pretty sure all of our eyes would’ve melted out of our faces
by now. So watch as much TV as you want,

  1. That's complete BS. There is a medical condition for people who stare too much at screens, and you're supposed to look away every once in a while to save your eyes/brain (20 ft away for 20 sec for every 20 min staring at screen). You can't use the excuse that "our eyes haven't melted out of our head so there is obviously no problem." That's like saying "you haven't died of climate change so it must not be dangerous, and same with everything else!" There is a NEARSIGHTEDNESS EPIDEMIC. Screens are so bad they've started what is called by some an EPIDEMIC of bad eyesight.

    I knew your show is mostly incredibly misleading, but this is just outright lying crap.

  2. Actually, this is pretty true, as long as you take a break to look at stuff far away, this basically calibrates your eyes and keeps them in good condition, because as a human, you aren't supposed to look at things up close 24/7. But actually, our eyes ARE worse, most people need glasses today, whereas in the sixties, it was far FAR less common.

  3. While I respect this show, I'm going to need a reference for this. Anecdotal evidence is not evidence at all. Get us the opinion of a doctor.

  4. For me it would if I didn't use glasses only cause as my doctor tells me, "if you end up unable to see out of one eye compared to the other the bad eye is gonna just be turned off by your brain eventually". And one glass is 4 times thicker than the other so I trust that call

  5. I have a similar question. Can your eyes be affected by screens and make your eyes more sensitive to light? I'm only asking cause since the invention of smartphones my sensitivity to the sunlight has become worse I think. Enough I need dimmed glasses. Is it cause of phones/electronics?

  6. I'm not sure about too much TV. But not getting enough daylight has been proven to make you more near-sighted, and TV watching is often done in the dark, while the sun is still out. So, watching TV may not hurt your eyesight, but it can promote behavior that will.

  7. All tvs emit blue light which is very bad for eye sight. Not just that, when people watch tv their eyes need to concentrate for hours and hence it weakens it. Just go to any optometrist and they will tell you watching tv for couple hours can strain your eyes and add in the fact that most people sit very close to their tvs this will weaken eye sight.

  8. Is cannabis bad while pregnant? I've seen research both ways. Before people hate on me for this, no I am not pregnant nor have I been, but I do need it medically.

  9. They did a study in China trying to figure out why within just a few generations, they went from most ppl not needing glasses to a majority needing glasses (and very strong prescriptions at that). It clearly wasn't genetic as it was within just a few short generations. They found that it had to do with sunlight. The more your eyes are exposed to sunlight (by actually going outside and playing outside), the less they need corrective lenses. Basically, there are proteins in sunlight that we need during development to build good eyesight. Playing outside is good for you, in other words.

    Of course, that doesn't help ppl like me where it is genetic, but that should be helpful for those ppl that don't have bad eyesight that runs in the family.

  10. only kind that can harm to eyesight is CRT. LCD, LEDs, OLED is basically harmless worst that it can do is mimic daylight and cause difficulty to sleep

  11. Yes and no, it's not screens specifically, really staring at ANY close thing for long periods of time can put a strain on your eyes, which can cause problems if done frequently

    This can actually be bad for children, as their eyes are still developing

  12. That was very misleading. Staring at screens for long periods strains/dries out your eyes. In extreme cases you can develop myopia (which has become more common since computers have become more widespread).

  13. You know there is research that not getting enough sunlight through your eyes while growing up can impair eyesight. Some people may blame it on screens, but researching the growing numbers of people needing glasses has found a correlation with how much children stay indoors. Its thought that a hormone isn't produced without an hour or two of sunlight a day.

  14. Yes it does. Looking at Asian countries were many students study hard reading then go home and look at computer screens all the time they end up having terrible eyesight.

  15. as many commented, Adam took things too lightly and missed the point by a long margin

    another thing people didn't point out and is already scientifically proven is that current device screens (with their blue light) can severely impact your sleep quality if you use before sleeping

  16. I think if you sit really close to the tv it could cause eye strain. Even books might do so. I've had bad eye sight ever since I became literate (anecdotal and probably coincidental) and people in rural areas of China have better eyesight than those in urban areas (evidence?). But if what you are doing is more fun than walking around outside or making money, it's probably worth it.

  17. Haha, The first thing I found when I googled does tv ruin your eyesight. Answer: Contrary to the popular myth, sitting too close to a TV will not damage your eyes but it may cause eyestrain. Children can focus at close distance without eyestrain better than adults. … There is no evidence that this damages the eyes either in children or adults.

  18. My PC has been ruining my eyes. Every now and then whilst I'm looking at a screen I'll get eye pains. So from personal experience, I can conclude that this is wrong. I'd like to see an actual episode have this in it. It's something that needs greater explanation. Because I have no idea where this conclusion came from.

  19. It's actually that sitting too close to the screen can hurt your eyes, cause headaches, and some disorientation. It's documented well enough that ophthalmologists recommend looking up from your computer screen periodically to allow your eyes to refocus on something farther away, to minimize the effects.
    (Don't believe me? What happens if you wear a VR visor- a screen literally inches from your eyes- for too long? Headaches. Disorientation. Reduced ability to focus your eyes for a short time.)

  20. Yes, the tv causes the eyes to focus at the improper distance. The screen's light appears to be coming from slightly in front of the screen and then it appears like the light is coming from behind the actual screen. This causes the eyes to adjust focus slightly in a process called accomodation. The light from screens in not-uniform from pixel to pixel and the light is also not uniform across a pixel.
    Older technology tvs have an actual light variation that can be easily detected. Newer tvs are getting better but they are not yet safe t use for long periods of time. Reading on a computer is definitely bad and the source of many men feeling insecure. The slight adjustment in focus by muscles of the eye keeps bending the lens so that almost everyone has myopia or nearsightedness. You need to bend the lens to see up close and relax the lens to see far away. TV is way worse than looking at things up close because the light you are focusing on keeps changing. Electronic ink in black and white does not cause this problem.
    Light while sleeping can also cause these problems. Candlelight reading caused the non-uniform light in Malcom X's nearsightedness and probably Ben Franklin's nearsightedness also.

  21. You might want to distinguish between TVs as Cathode-Ray-Tubes and modern TVs as LCDs, OLEDS…etc. Having 3 Electron beams (for Red, Green and Blue) crashing on the face of the tube is like having a mini CERN particle accelerator in your home, without all that life-saving shielding stuff.

  22. TV destroys your ability to think rationally and critically about important social issues but your eyesight should be fine.

  23. It's far more complicated than most make it out to be, but the original bromide (and it's typical conditions) is correct:

    Part One of the equation is the general plasticity of human physiology. (In layman's terms, our bodies naturally adapt to better align with our usual activities.) Where this topic is concerned primarily relates to our 'default' focal distance – the distance we are from what we spend the most time looking at is where our eyes eventually 'optimize'. This warning originated in an era when televisions were more furniture than functional; a 19" screen was typical, and kids would sit on the floor roughly an arm's length from the screen.

    In this manner, the bromide is more poignant than ever – hours sitting at a computer or, worse yet, staring at tiny mobile devices even closer for hours on end each and every day!

    Part Two if the equation has to do with the technology itself. When this bromide originated, TV screens exclusively used CRT (cathode ray tube) technology. Electrons striking the phosphorous coating inside the tube created minute broad-spectrum radiation – harmless in small doses and/or from a distance but the cumulative effects of extended exposure at a close distance gradually damaged the cones (which are relied upon for color vision and spatial perception). This was exacerbated by the fact that the highly-reflective surface of CRTs meant most other light sources were minimized when watching TV, dilating the pupils and exposing the cones to even MORE radiation.

    In this manner, the bromide has become a non-issue – LEDs and LCDs have long-since replaced CRTs, and modern screen surfaces are far less reflective than their ancestors. Not only has the troublesome radiation been eliminated but the disproportionate illumination of the screen relative to the environment has been greatly reduced.

    By and large, this has become a moot issue except among extreme PC gamers – far less relevant to mobile gamers as, though looking at closer and smaller screens, they look up and focus on normal distances throughout while PC gamers seldom look away from their monitors. While phosphoric radiation is no longer a factor. the close distance and disproportionate illumination (typical of PC gamers) remain relevant factors which contribute towards eyesight degradation.

    Generally speaking, however, watching TV is no more damaging to one's eyesight than being a bookworm – it is ancillary factors (lighting, distance, etc) which are the complicit factors rather than the activities themselves.

  24. In fact, that's not watching screens that ruin your eyesight: that's focusing for a long time on something, and reading books is part of that! Eyesight problems have drastically increase with the democratization of books in the XIXth, and we have never read as much as today – yes, when you read an article on buzzed or a text your mom send you, it is still reading.

    But I don't believe that because reading do have an effect on your eyes, you should stop reading. After all, humans started to develop teeth cavities after the development of agriculture – cereals are slow-burning sugar, but sill sugar – and it does not stop anyone eating pastas 😉

  25. There actually is a study showing that LED light is harmful to your eyes. The reason for this is that LED mix blue and yellow light to produce white. But blue light passes the cornea with no resistance. That can lead to a higher risk of maculadegeneration. That is an illness resulting from to many damaged cells in the center of your vision.
