Did I Get the Correct Eye Glasses and Contact Lens Prescriptions?

6 months ago I went to a new eye doctor. I hadn’t been to the optometrist in 5 years. All I know from my old prescription was Right SPH: -1.25 and Left SPH: -1.75 and I have an astigmatism. I had no problems except at night things were a little blurrier and my glasses broke.
The new doctor "inherited" my file and after an examination (machine test and he checked them out) said my eyes had gotten better, but the astigmatism worsened. He said that my new vision was Right) SPH: -1.00; CYL: -0.75; AXIS: 174 and Left) SPH: -1.25, CYL: -0.75; AXIS: 14. However he wrote me a lower prescription. SPH was -0.75 (right) and -1.00 (left). He told me that my eyes would get worse if I had the stronger prescription. At first, it was slightly harder to see with these new glasses. But I think I’ve gotten used to them and my old glasses seem a little strong and I can definitely tell the difference in astigmatism correction.
Yesterday, I went in for a contact lens fitting and the pair he gave me to try out are weaker than my glasses. The prescription for the contact lens read a little differently than the glasses. Instead of "SPH" they say "D". The contact lens prescription is as follows Right) D; -0.50; CYL: -0.75; AXIS: 170 and Left) D: -0.75; CYL: -0.75; AXIS: 10. I told my doctor that it’s harder to see even though I can "read the letters on the wall". I want to make sure I’m getting the right prescriptions. I know I have a relatively low prescription. I’m a 28 year old male in good health with no history or medical issues.
Thanks in advance.

contact lens rx and glasses rx are typically different because of the distance from your eye… the contact sits right on your eye and the glasses lens is further away. That would be why the difference.
He probably gave you a lower prescription to avoid the accommodative response. People who are overminus focuses behind their eyes, and your eyes respond by using your crystalline lens to place it on the retina. Over time, this may cause complications. So a way to avoid this is to make sure that we dont overminus you.
With minus prescriptions, your contact lens RX will be lower than your spectacle. It is the opposite with plus prescriptions. Also, you have a decent amount of cylinder on your lenses. Typically, contact lenses come in axis increments of 10′s. Since you have a 174 and a 14 on each eye, he can only prescribe you contact lenses that are at axis 170 and 10, respectively. This is partially why you’re not seeing as clearly with contact lenses.
