Making your vision blurry?
I can make my vision become blurry....I do it [not always because something tells me it's not healthy for them] but not sure how. How does the eye do it?
Additional Details

you need glasses if they start doing that

I can do that 2 but i don't know how the eye does it

when you look straight ahead your vision is clear, but if you look diffrent directions with both eyes, it gets blurry. For example try looking at your nose with both eyes, itll get blurry.

Post also the meaning of "blurry"

depends what you are focusing on. The eye tries to give a picture to the brain but it may have two focal points or maybe only 1 eye can see it.

One dollar and NINE CENTS!!!!!
I think it would actually be the brain doing it. Making the eyes unfocused.

Cross your eyes = blurry vision.
Eye strain sometimes causes it, too.

you are crossing your eyes and/or focusing on something closer to you making everything behind it seem blurry

I can make your vision blurry too.....

What, like when you look at one of those 3D pictures like on that Seinfeld episode?

You're relaxing your eye muscles. No big whoop. If it doesn't hurt physically, then it probably doesn't hurt your eyesight and it might even be good to work those little muscles.

The eyes blur the vision by focusing the lense differently.

Sort of how having a magnifying glass too far away from your target blurs it.

Note for example that when you blur your vision, objects really far away don't blur that much. compared to close range.

You are unfocusing, aka soft focusing. There is actually a way to use this to expand your panoramic vision. We use it in animal tracking a lot. It actually exercises your eyes.
