I have prism corrections in my eyeglasses - up/down 1.0, Do I have to get the prism?

Get the prisms and be fitted by a qualified optician. This is very important on many levels. The worst that can happen is you can reduce your ability to see to the point of vision disability.

Proper alignment of the eyes is necessary for correct depth perception. The misalignment (anisokonia) that is corrected by the prisms assures that the image in each eye is properly aligned to the other eye. If not aligned properly the combined image may appear blurred, the eyes may attempt to correct the blur with focusing, and you may experience headaches, nausea, vertigo, loss of depth perception, and other symptoms consistent with eye strain.

What is more important is that the brain will not accept the two misaligned images for long. It is highly likely that the brain will "shut down" the images from one eye. The eye would have the ability to "see", but the brain will ignore images from one eye. This is called amblyopia and can rarely be reversed. You would not notice this gradual change at first, but you could very well lose the ability to see properly with one eye. It is also possible that the brain will ignore images from both eyes, resulting in low vision quality that cannot be corrected with glasses.

Those prisms are very important to your vision health.

Seriously...I tried to go cheap with my daughters glasses (she has had them since 4 years of age). For one, my daughter snapped two pairs of $150.00 frames, and then the shop did the prescription wrong so for months one of her eyes wasn't getting the right vision to correct her eyesight. Now I have gone expensive Titanium frames (they bend and don't snap as easily) and I will only go to one particular shop now, they are very professional (and cost more) but I have never had any problems since going there. My daughter needs aspheric lenses and has a stigmatism as well. You may need to change the lenses too when the optometrist advises, they cost me (without the frame) about $200.00 give or take. My daughter sees a child specialist for this and goes every 4 months at a cost of $120.00. It really hurts the purse, but unfortunately what you pay for is what you get!!!!

If you don't get the prism you may see double and have headaches.

You could buy the frame only (without lenses) from an online source and take it to a real optical to have the lenses put in.
