Dark Eye and Light Eye

[DarkClaymore]

I don't know if it is a known fact and whatever it is the right forum for it.
Anyway...


Last summer, my parents went on a vacation (I hate vacations, so I didn't go). So I was alone at home for something like 2 weeks and of course, I was playing on the PC till late and such. I prefer to play without light because you can see the screen better.

While daily doing the same thing, I noticed something interesting.
I sit for along time in front of the PC. The, when I go to drink something and to take a little break, I can hardly see a thing in the darkness.
After sitting a few minutes in the darkness, I started seeing better and my eyes got more used to it. Then, after my short break is finished, I go to the PC again and when I look at the screen, my eyes hurt for a few seconds and it takes some time to get used to the light again (like when you exist from the cinema and see a daylight)

After that it happened so many times, I decided to do an experiment.
I choose one eye to be a "Light Eye" (an eye which easily get used to light) and "Dark Eye" (an eye which sees better in darkness).
So when sitting in front of the PC, I closed my Dark Eye and when in darkness, I closed my Light Eye. After letting both eyes to get used to what they need, I checked whatever everything works.
I memorized how good I see in darkness with the Dark Eye , and then quickly switched to my Light Eye. I was surprised that my eyes actually were very unbalanced. I hardly saw anything with my Light Eye, while the Dark Eye saw much better. The same goes about getting used to light. The dark eye hurt a little in front of light, while the Light Eye didn't.

I was thinking to train my each of my eyes to be different, but I gave up because I think it is not good to have such unbalanced eyes.
What do you think about this?

What do I think about this? I think it was already covered on Mythbusters. The only difference is that they used an eye patch to develop their "dark eye".

Personally, I think it's too much of a hassle to actually divide your vision like that. If you're driving a car, you want to be able to see as much as you can, two eyes are better than one.

I didn't know that...
I know Mythbusters, but I don't really watch it (my friend showed it to me only once and I was too lazy to watch it myself afterwards).

So it is pretty much the same then, only that I didn't have an eye patch... I probably would have used it if I had one...
I thought I came up with something original...

Well done to you for doing experiments like this. The results are interesting, though I guess they reflect what was meant to have been done by pirates in order to aid their eyes. However they did it to both eyes as far as I am aware, so splitting your eyes to that one sees one way and another sees another way is probably quite different.

I don't think it would be beneficial to train your eyes seperately though... You'll lose all sense of balance and it can't be useful. Over time they would correct themselves anyway, so you'd probably have to constantly repeat those procedures a lot even to have those effects last for a short while.

I was actually taught in school about this more than a year ago. The human eye has photoreceptor cells which are mainly divided into two : rods and cones. The rods are the ones responsible for vision in dim lights and the cones are the ones responsible for bright light vision. In bright light, the cones are more active and if you immediately look at objects at dim lights, it takes some time for the rods to adapt and take over the 'handling' of the light. (At least that's what I remember, I was an awful Biology student back then...)

How long did you do your experiment, Claymore? I bet it's annoying to only see the computer with one eye closed.

Not for too long. I am not sure how much I was in front the computer.
I doubt it was more than 1 hour, as I was tired and had nothing to do.
More annoying was to walk in the darkness with one eye, and then lying in bed with one eye (I always have hard time falling asleep, so I lying down with open eyes for a while).

Then, after lying for a while in my bed, I decided to check the results of the "experiment". I didn't really expect that something'll happen because I have tons of strange ideas which never work, or I just can't test them.
So I went and turned on the light in order to check if the Dark Eye has problem with it. Then turned it off and checked if the Light Eye have problem in darkness.

But then I thought. Light Eye will be closed when I am in dark place.
But when your eyes closed, you are supposed to see nothing, which is the same as darkness. So I guessed that maybe the Light Eye will get used to darkness while it is closed. So basically, it is impossible to make "perfect" Light Eye.
I don't study Biology, so I don't really know.
Do you have idea whatever I am right? (too lazy to do it again and confirm)

Yes, you're right. Although I think you could get a more accurate "experiment" by making sure that you use the 'dark eye' in darkness first, then close it and then use the 'light eye' in bright light. Then test both of them seeing in darkness. That way, your bright eye will barely get closed.

I think I've read an article, of some sort, on an experiment of some people who were put in a dark room (or were blindfolded, I can't seem to remember) for a few months. After a few months, they were exposed to light and it was so painful that they need to be introduced to light slowly. The introduction process also didn't take only a few days, it was more than a few weeks. I thought you'd be interested in the article, so I'll post the link (if I find it) as soon as I find it.

From what i recall they did this with only one eye that way they could see in night battles. Thoguth i'm not 100% on the info so take it with a grain of salt.

BoT... I think it would be very useful if his idea could be implicated without too many adverse affects. No more stumbling around after hrs getting a glas of water. We wouldn't need to sheild our eyes from the sun afetr seing an afternoon movie and such The draw backs make it seem almost not worth it though. Gotta have 2 eyes to drive (reccomended). What if you light eye gets infected with something and is no longer useful? Yo uwouldn't be able to do much in the day time now would you? No, i don't think so.

While the idea is fun to toy around with, i think we were meant to hae to light eyes that adjust for a very important reason. The reason? i haven't a slightest clue xD
