A week, before reporting it.
Your Rx as given is one that might well give trouble, even if perfectly correct, given that the axes of astigmatism are almost opposed.
Try looking one eye at a time and see if the vision feels sharp *and* comfortable, and if then the "oddness" re-appears with both eyes open.
If it feels odd with one eye or the other, then there's every chance the Rx is simply off, on one side.
But if it's only present with two eyes together then it may be the crossed astigmatic axes. If you're right-handed a 0.25 or 0.50 sphere lens in your left eye might produce a better overall effect. Giving each eye its best Rx is only *usually* the right answer to Rx prescribing.
Two weeks is more than enough time to struggle.
You could be a poor candidate for contacts fro a variety of reasons, such as poor tear qnatity/qualirty, but your left Rx is not one often turned into contacts: astigmatic lenses have to maintain orientation in the eye (unlike sphere lenses, where it doesn't matter if they rotate) , and achieving this makes them thicker, more expensive, and sometimes needing several attempts with different brands to get right.
Therefore small amounts of astigmatism, like 0.50, are often ignored, slightly compromising the vision in order to avoid the other downsides. In your case that might be a plus!
Otherwise, you'd have to enquire as to the specific details...
I've not seen your eyes.
