What Do The Numbers Mean On Your Contact Lense Rx?

Can any one explain what the numbers on your prescription?
I know that 20/20 is perfect vision, but when the numbers are negative numbers, explain what it means and when your eyes are really really bad, meaning that you can’t see your own hand if you hold it straight out in front of you (without your contacts or glasses of course) what would your numbers be to be considered legally blind?
when I say that you can’t see it I don’t mean that you can’t see anything, but if you had a paper in your hand, you probably couldn’t see what was written on it even if it was the size of the biggest letter on the eye chart. and while I’m asking, I thought of another question
If you wear corrective lenses all the time, do your eyes become dependent on them, meaning that they will never get stronger, almost like building an immunity to antibiotics?
Wow, I think I confused myself on that one, but if you understand what I was trying to ask, answer please. I hate wearing contacts and glasses just the same, considering lacik surgery, but was just curious about all this stuff, and oops sorry, another question, is there any thing different I would need to do besides ask my eye doc about the surgery? meaning is there any waiting period, or anything that he will make me do before he can recommend, or do the surgery. once I decide, I am a very impatiant person, and don’t like to wait, I like instant gratification. I also have an astigmatism will that be a factor in the surgery, meaning that I couldn’t have it done.
sorry so long, I started asking, and a dozen more questions popped into my head =(

How Severe Is A -.25 Astigmatism? And What Does X105 Mean?

I went to a new eye doctor today, and instead of my usual OD -2.75 sph, OS -1.75 sph prescription, the new one reads OD -2.75 -.25×105, OS -1.75 sph.
I did some research online and apparently this means I have an astigmatism in my right eye. I’m a little confused because the doctor did not discuss this with me, and at 29 years old, I’ve never been diagnosed with an astigmatism before. I’ve also never had blurry vision that I’ve noticed.
Is it possible to develop one this late in life? If so, how severe is this -.25? And what does x105 mean?
I have a couple of boxes of contacts that are not toric lenses… will it hurt me to continue wearing them?

New Contacts–what Does It Mean If I See Shadows/clouds Around Signs And Lights At Night?

I have new contact lenses which seemed perfect in the eye doctor’s office (had no trouble reading the eye chart), but I’m having issues seeing with them out in the real world, especially at night. When I drive, street lights have a hazy cloud around them, and street signs (especially the reflective ones) seem to have shadows (almost like seeing double). And I notice the words on the sign are harder to read as well.
It’s a brand new pair, and a new prescription. Is the prescription power too strong/weak, is my astigmatism over/under corrected? I don’t understand why they seemed fine in the office though.
Thanks for any help!

What Does It Mean If My Contact Lenses Don’t Move Anymore When I Blink?

I’ve had them scince wednesday and they’ve been working fine but I think I noticed it today or like the last time I wore them(which was the day before yesterday because I went on a rafting trip on saturday which we would be throwing water so I couldn’t wear them) that at least one wasn’t moving at all when I blinked I would put some of the contact solution in my eyes like drops for moisture they would move normally at first but when back to normal dryness they would stop. Other than this my contacts have worked normally I just need to get a slight change in my left eye perscription because of my astigmatism and I barely even notice them any more. Today I took a nap of about an hour with them on and when I woke up they were just like they were this morning so yeah. I just want to know what it means if they are like this and if I need to change anything or if its something to worry about.
