Vision issues post Copaxone injection

I was diagnosed with MS a month ago. I got my first Copaxone injection on Wednesday 11/22. Something very strange is happening with my vision. I’ve had the same prescription for contact lenses/ glasses for over a decade; and the correction was fairly minimal- just clarified things far away. But now today (one day after first injection); if I wear my glasses- they blur anything close. Weird- right? They still work as always for distances...
I might also add- I also had hernia surgery on that same Wed (of which I was under general anasthetic) and took a dose of oxycodone for pain later that same day.. might something be happening with such a cocktail of meds?
I’m really hoping that’s the case; and I am not relapsing already!
I haven’t taken the oxy since 9am; and my surgery was now over 32 hours ago- and my vision is still messed up....
Any thoughts?!
Of course with the holiday- I’m not getting through to any doctors...
