Tell her that short-sightedness is more strongly affected by text size rather than computer screens, and that reading glasses, or books with larger fonts will be of much greater help.Jailbird408 said:I did confront my mother, as best as I could. Turns out the astigmatism was just a hunch, and the truth is that I am actually getting increasingly short-sighted. But she won't budge on anything else. If she really is making up these treatments in full knowledge that it won't make a lick of difference whether or not I follow them, then she's not admitting it.thethingthatlurks said:I'm not saying it is not possible to go blind from visible light (~200-750nm), but that would involve some serious damage to your eyes, optic nerve damage, rod/cone degeneration, and so forth. It is physically impossible for light in that wavelength range to cause any damage otherwise. If you have such a condition, I would encourage you to find out immediately!Jailbird408 said:Hmm... Interesting. Maybe ilikemilkshake was right and mom DID bribe the optometrist to get me to go outside more. Then again, the sun CAN make you go blind...thethingthatlurks said:Take it from a guy who has worn glasses for the better part of his life: astigmatism will NOT make you go blind under any circumstances. Furthermore, even the old CRT monitors were never hazardous to your eyes at reasonable distances. If you have an LCD/LED monitor, you will not have any problems, except perhaps for eyestrain from sitting in front of it at short distances for extended periods of time (harmless, though irritating at times).Jailbird408 said:Anyway, when my mother and the optometrist were talking to each other, I overheard the word "astigmatism" being thrown around. So is anyone's wondering what exactly I have, that's the best answer I can give you.
Now here's a fun fact: light from monitors is not different from other light sources, at all. If the monitor is going to make you blind, so will the sun, a lamp, car headlights, digital clocks, candles, etc.
If that's really what your optometrist said, I suggest you find somebody who isn't an incompetent quack. Otherwise, I'd be curious to hear the exact nature of your condition as well. At any rate, the best of luck and health to you!
UV light is a different story, as it is energetic enough to break chemical bonds (visible light typically only causes excitations from HOMO to LUMO, at least in organic compounds). The interaction of light and molecules is really quite interesting, and much too broad a subject for me to explain here, sadly. But here's something I want you to take away from this: the shorter the wavelength of light, the more energy it has (blue/violet are more energetic than red light, for example). More energy means...more energy! A tautology, I know, but the rules of quantum mechanics are such that two photons of energy X do not cause electronic excitation of 2X in a molecule, which in our example would be enough to break a bond. In other words, if the optic receptor were to require light of ~100nm in order to break apart, two photons of violet light (~200nm) would not be sufficient. This in turn means that brightness, which is another measure for the number of photons that you see, is not going to harm your eyes. Yes, there's the whole snow-blindness thing, eye strain, and so forth, but those are temporary effects.
I would seriously confront your mother about this. If she admits that it was all just some way to get you off the intertubes, kindly relay the following:
"What the fuck is wrong with you?! Misinforming a child about health issues is no different from any other form of child abuse. You fucking suck at being a parent. Go die in a fire."
But seriously, 30+ hours a week in front of a computer screen is way too much, particularly if it's not your job. Go outside!! Not for your eyes, but for general well-being.
