Why and how is reading in dim light hurts our eyes?

Question

??

Answer 1

I think that is just an old wive's tale. I don't know where people seem to get these strange beliefs; like reading in the dark, sitting too close to the TV, or wearing someone else's glasses will damage your vision. Most of the time when someone can't see well, it's because the eyeball is too long, too short or the cornea is the wrong shape; none of these activities is going to change the shape of your eye. You might get headaches or your eyes might feel tired, but it isn't going to physically damage anything.

Also. they are always telling people to eat lots of carrots; like that is going to reverse nearsightedness or something! I used to eat lots of carrots and I still have to wear glasses; (maybe I should sue the carrot company, obviously their product was defective!). Unless you are so dirt poor that you don't get a decent diet, I don't think eating extra carrots is going to do anything for you.

Answer 2

It doesn't hurt them, per se.
What it does do is cause them to strain. My eyes were so strained, my doctor was only able to detect my need for reading glasses. When I came back for my appointment for a dilation examination, he noticed that I also had a distance issue. He said everything was so tight from the strain, that he could not tell. My plan only paid for one pair of glasses, every two years, and since I didn't drive at the time, I waited. I had no idea that my need for bifocals was causing the massive headaches.

Just read in proper lighting, and don't watch television in the dark. No one has anything to gain by telling you these things, falsely. More than one eye doctor has told me both, since childhood. They also assured me that trying on someone else's glasses wouldn't hurt me, but trying to get through an entire day with them would make my head really hurt.

Making your eyes strain to read anything will eventually damage the eye. If she wants to fall asleep with the book give her ten minutes with the light on and then check and see if she is asleep and take the book and turn off the light or give her a timed light something that lights up while playing a song and once the song is done the light will go out.

Answer 4

The darker the lighting the more your eyes have to strain in order to focus on what you are read ind. Some symptoms of strained eyes could be eyes watering and eye twitching. It is said while Reading and/or while on the computer people have the tendency to blink half as much as normal which in itself strains the eye, therefore by adding another outside factor to it such as poor lighting will strain your eyes even more.

It's not really a problem for a young person to read in dim light but it definitely becomes one for someone who is older. It's harder for us to read in dim light, especially with small text. I can see small print just fine in bright light but I have problems with it in low light. I don't have this problem when I'm not wearing glasses or contacts but I do have it when I am wearing them.
