Are eyeglasses supposed to do this? ghosting?

I've never had eyglasses before.My university offers students free eye exams, so I thought I'd take advantage. I'm about 40 and starting to notice and can't read up close so much. The following prescription was determined by the OD:
Sphere Cyl Axis
OD +1.00 -0.50 153
OS +1.25 -0.75 20

I plugged the numbers into zennioptical.com and picked out frames I liked and ordered my first pair of glasses. I haven't been happy with them though. I first noticed objects in the distance are about the same sharpness compared to w/o glasses, sort of, but seem hazy. The doctor said all distances should be improved. Then I noticed when watching subtitles on my TV screen, I see there is a distinct ghost image of the text and I see it in both eyes.It is very distracting. I don't really require eyeglasses so it looks better without. I can now notice ghosting in all kinds of things now. Any lighting, but the more contrast between edges, the more noticeable.

I took my glasses to the clinic and they took them in the back and said they are within tolerances of the prescription. The OD did a full recheck of my eyes, and determined a practically identical prescription. What is the cause of the ghosting? She doesn't know why I would see ghosting and referred me to the optician. He said something about spherical lenses versus digital, but I don't really recall now. The glasses work pretty well for up close work where ghosting isn't much of an issue. I don't think the prescription is quite right, since I can see much sharper in my left eye the closer I look through the bottom of the lens. Not sure what I should do. The clinic said I could try glasses through them, which is an expensive experiment. Could their equipment not be calibrated right? Thanks in advance.
Added (1). The optician measured my PD as 66.5 with something that looked like a serious Viewmaster. Maybe was Luke Skywalker's binoculars. Kidding aside, They also had me look at their nose while they marked my pupil location on the lens, and they also marked the optical center.It lined up vertically with the optical center of the lenses.My pupils are about 5 mm above the marks. If I raise the glasses about that much, there's no change. Optician said that was typical for the style of frames I had and not a concern.

I'm not seeing a halo.It is a distinct faint image. Best example is credits in a movie. I see white text on black. If I back up far enough, I can read the faint (gray) text. ghosts are side to side (and a little lower). If i tilt my head the ghost text will rotate above (or below) the original text, but it is still side to side relative to my face. Glasses are level on my face.

I see the same thing with LED in the dark (easy to see contrast), or in the li

Added (3). … ght if the LEDs are bright enough. Yesterday in the waiting room before having my eyes rechecked, I noted how the leg of a chair, contrasted against the carpeting, and I could see another distinct ghost image of it.

I emailed Zenni support and they requested I scan and reply with my Rx and PD which I just did. They will check that I entered it correctly, which I was quite careful of doing, but you never know.

I can try +1 reading glasses and see if I see the ghosting.
