What sould I do???

Okay, I just got new eyeglasses today. Untill now I wore my glasses for movies TV computer (im wearing them now) Video games and such. I was okay with that untill about 3 weeks ago me and my freinds were out and they told me to look at this sign that was about 100 feet away. I was confused and said its too far away to see.They said that it was fine from there and I should get checked out. I was really nervous then so I asked one of my freinds moms who's an assistant for a eye doctor. She said I definatly need them all the time. But my eye doctor said i can do what evers comfertable.Then today I was with my mom in the car and i couldnt read the licence plate of the car 2 cars infront of me. The licence plate of the car infront of us was blurry but i could sqint out 3/4 of the letters. Should I wear them all the time or only 4 movies and such.

Okay all that happened in my "story" is WITHOUT glasses

Your eyes are cameras. There are lots of different types of cameras. Some are made to take pictures of things far, far away. They sit on the back of telescopes which are focused far away. Very nice.

A camera that sits on top of a microscope has a focal point that's very, very close. It takes pictures of things almost right next to the camera.

Which is the better camera?

Your eyes are focused nearer than far away. It doesn't mean they're not good cameras. They're just focused sort of close. How close?

The formula used is P=1/d where the d is the distance in meters. If you needed to 'weaken' the focus of the camera, you'd find how powerful the camera was, then put a lens in front of it equal to it's power, but the opposite type of lens.

So if you are focused at a meter in front of you, which is 39 inches or so,...a yard being 36 inches...you'd need a -1.00 lens to move that focus out to infinity...or far away.

If you were focused at a half meter in front of you already, because you are shortsighted or nearsighted or myopic (you pick the word you like), you'd need a -2.00 lens to move the focal point out.

Focused at a third of a meter...a -3.00.

Focused at a quarter of a meter, a -4.00 lens...and so on.

If your Rx is sherical, it means it's sort of like a chip off of a basket ball, or volley ball, or soft ball...a round ball. The curve from one side of the lens to the other across the middle is always the same curve. When light goes through the lens, for instance from left to right with the lens in the middle, the center part of the lens, the glass on the front and back, are flat, just like a window. There's NO power there. As the light rays move away from the center of the lens, they hit the glass or plastic at an angle and they bend. They bend in such a way that they cross that central undeviated light ray at some distance from the lens on the right side.

How far the focal point is, is the P thing. So if it focuses the light at a meter, that's a +1.00
half a meter +2.00
third of a meter +3.00
tenth of a meter +10.00

The more powerful the lens, the closer the light rays are bent on the other side of the lens

So when you look at the signs, or the car up in front and squint, what you are doing is removing the 'power' of the bending lens so you are using the light rays that don't bend very much. You can do this my squinting, or holding up three fingers and looking through the little hole in the center...and things will be better focused out there. You are using a "pinhole", which are the center undeviated light rays. As they have a very large depth of focus, you can see more clearly at a distance.

Exercises won't make you be less near sighted. Relaxing might a little, but if you are focused at a certain distance in front of you, moving the muscles on the outside of your eyes just isn't going to change the camera focus.

Take a camera. Point it at the distance holding it with both hands, the right hand on the right and the left hand on the left. Now move the camera back and forth in a swinging manner. Does it change the focus of the camera?
Might tire your arms after awhile, but does it do anything to the inside of the camera?

Na.

Exercises like this can be used in some cases where there's an imbalance of the extraocular muscles where there are problems with muscle or nerve weakness on one or both sides. This can help one learn to maintain fixation with a weak eye, and this is the basis of orthoptics, but it won't change the focus of the camera, the eye itself.

So if you don't wear your glasses you won't see well. That's all there is. If won't hurt your eyes to take lousy unfocused pictures, you just won't be able to see that cute lady over there very well and the guys next to you will. And who cares? They don't.

Why would you not want to see clearly? Looks? Is that what makes you a nice person or not, or handsome or not? or ???

Na.

We live in an age where we can take someone who is focused at near and with a little pair of glasses, he can see very clearly far away. When you get older, like 40 or so, you won't need glasses to read as soon as your friends, maybe never if you are focused already at a reading distance.
