Make your eyesight worse if using pc/tablet for long time everyday?
How bad is it to your eyes if you use iphone/tablet/pc for long time everyday? I use my iphone for 8hrs a day or more playing games etc… Can it for example make your eye from -07.00 to -07.50 because of stressing your eyes too much? Can anyone certified answer this question please thanks
No. That's a myth. A very popular myth, but a myth. There are some very poorly designed studies (so poorly designed that the results are not believable) that suggest that close work will make you get nearsighted sooner, but even those studies didn't find that you get more nearsighted. It's your genetic destiny. Your genes control how nearsighted you will be as you grow, just as they control how big your nose gets.
- Would it be possible to make an app that makes sure your posture is straight when using your iPhone? For example; it could use a camera to make sure your face / neck are upright or it automatically locks
- What is your favorite game on your tablet or mobile? Mine is Gun Bros 2. I like action and adventurous games. What are your favorite games? I get very few games on iPhone and I'm looking for more to play, your recommendation will be very helpful I think, and 10 points will be given out. Preferably iOS games, thank you.
- Tablet snapshots on the Tablet and iPhone? I'm not very tech-savvy guy, go please forgive me. But does a Samsung note 10.1-the 2013- snapshot consume more memory space than a iPhone 4 in general? Here are the dimensions(again I do not know what I'm doing) Tablet(Note) 10.1" widescreen 1280x800 WXGA TFT LCD 149 pixels per inch (ppi) iPhone 4 640 x 960 pixels, 3.5 inches (~330 ppi)
- Should I buy a laptop or a tablet? How do pages display on a tablet? I have an iPhone 6s Plus. It almost seems redundant to buy a tablet, but they are more affordable than a laptop. I prefer the way web pages display on a laptop. I have never had a tablet, do they display pages more like a phone or a laptop?
