Shouldn’t Eyeglasses Make Each Eye See Equally Well?

I just got new reading glasses yesterday. For years my left eye has been far-sighted and my right near-sighted, although not to the extent that I need glasses all the time–just for reading. The optician also told me one of my eyes has an astigmatism, but I don’t know which one.
Each time I have gotten glasses I have noticed that the left lens never, never gives me the same vision quality as the right lens. This has happened every single time I’ve had an exam and had to get new glasses. The right eye is GREAT and I’m amazed at how out-of-focus life really was for me. But the left eye, compared to the right, is definitely not as clear. In fact, there is barely a difference between wearing the glasses and not for that eye.
Is this part of a corrective process, and my left eye will be better after a while? I’d really appreciate any info. I am 31.

Do Eyeglasses Mess Up Your Peripheral Vision? Do You Use Your Peripheral Vision Much When You Drive?

I’ve been wearing contacts for most of my life. But now I have an astigmatism and the lenses to correct it sometimes shift, causing blurry vision. I’m afraid this will happen while I’m driving. Laser surgery is too expensive right now, so I’m thinking of getting eyeglasses to use while driving. My concern is that the glasses will interfere with my peripheral vision. Not a problem most of the time, but will it affect my driving?

Eye Doctors, Please Read! I Picked Up My Eyeglasses Today And My Vision Is Improved, But Not 20/20.?

My right eye is corrected to 20/20, but my left is only to 20/30. They checked the prescription on the lenses and they are correct. The doctor said my left eye may need “Stimulation” to improve. He explained that this meant my brain had basically been shutting off the images from my left eye because my right eye was much stronger for so long and with my new glasses, “signals” from both eyes should be sent to the brain and I will be corrected to 20/20 after wearing them for a while. Is this something other new glasses wearers go through?
My prescription in both eyes is not very high I don’t think, .75 in my right and 2.00 in the left. (For distance) I also have astigmatism in the left eye. If it makes a difference, I am 22 years old and this is my FIRST pair of glasses ever.
Thanks!

What I don’t understand is what OD-ADD is, I don’t see anything else on my contact lens that can be used to fill it in. Also, my left eye contact lens (non astigmatism) doesn’t have the CYL or AXIS numbers. Are these for astigmatisms only?

Which Is Cheaper, Eyeglasses Or Contact Lenses?

I have a very bad myopia and astigmatism, and I’m not sure which of the two is cheaper. I’ve been using eyeglasses for 10years, and I wanna try contact lenses for a change [if it's cheaper].
