There is hardly any clinical evidence that tablets or smartphones affect long-term eyesight in children or adults, and it isn't because of a lack of trying. Dozens and dozens of studies have tried to link electronic devices to poor vision, but time and again the main determinant is heredity. Even the more common problem of eye strain from focusing at close visual ranges (playing on a tablet, READING A BOOK, staring at a chessboard/gameboard, etc.) are temporary and can be recovered just by looking away. True myopia (nearsightedness) is affected much, much more by the parents' genes than any external factor. So stop screwing up your toddler with a false myths not based on facts and messing up their brain...It's not necessary!
All electronic devices emit blue light (shorter wavelength and more energy) that is both good and bad. But the greatest exposure to blue light by far is, well, being in sunlight (ie PLAYING OUTSIDE.) While blue light is known to boost alertness and help memory/cognitive functions (and possibly elevate mood), the main concern is how it affects the circadian rhythm. Watching television or reading a tablet late at night affects that cycle and could cause sleeplessness or fatigue.Macx2mommy wrote: ↑Oct 3rd, 2017 12:37 pmBased on what our paediatrician and optimistrist advised us, the back light on tablets and laptops aren't great for kids (adults too). It does put a stain on their eyes and the backlight impacts sleep patterns. My kids are avid readers, and use their laptops to download books that cannot easier get in paper copy. Both the dr and the optimistrist recommended getting a proper ereader, as they don't have the same lighting and it is better for their eyes and sleep. I don't know how much is safe or not, but there are studies that do show this information too. We are extremely careful with or kids eyes because due to genetics (not computer use) they may have lots of problems in the future.
I would like to hear their reasoning. Facts don't support their suspicion (at least not any clinical studies provide clear evidence) that eyesight is permanently affected by electronic devices. Behaviourly, has it really changed a child's social interactivity? My teen-aged nieces and my daughter grew up on electronic devices and while it can be argued that they were "socially-challenged" in their early years, they're not-stop chatterbugs now. Even my 8 year old son connected with his younger cousins at a wedding recently. Having never met some of them before, they all "bonded" over some stupid ipad game and having a great time all night.Cas77 wrote: ↑Oct 3rd, 2017 3:29 pmMy sister and her husband are both optometrists (sister is also part-time university professor) and are both quite adamant that it does affect a child's eye sight. My niece did not watch TV until she was 5. Now the problem was every time she went to a restaurant with a TV playing she would be completely fixated on it and not pay attention to people around her or to her food.
As far as I'm concerned, electronic devices are just another tool in the toolbox.
