Is this normal

[maydayp]

I'm near sighted and, for as long as I've had glasses (7yrs- 2 prescriptions) I've noticed that they cause a difference in my hand eye coordination, by making things look smaller then they are (I pinpointed this when I got contacts which makes everything bigger, and by looking through the side of my eye, at the edge of the glasses). Is this normal? most people I've talked to say they don't experience this. and the farther a way the object is the bigger the difference. (only obviously noticeable when trying to grab/moves something as it moves from within glasses to outside of the glasses, otherwise I can compensate for it, subconsciously)

Yes, this is normal. Concave lenses make the image smaller.
Glasses are worn at some distance to the eye and this leads to further aberrations.

Although a certain degree of minimification is normal with minus/concave glasses, It shouldn't be as obvious as your describing with a minus 2 perscription.  It is possible that your perscription has been overminused (too strong for your eyes).  If you are under the age of 35, you may want to consider a recheck of your glass percription with the doctor starting on the plus side of the spectrum and give you the minimum minus perscription you will tolerate.
