On/off Blurred Vision With New Contacts?

So I just got my trial pair of Frequency 55 Toric lenses today. I had no discomfort, but for the first couple hours I had them in, my vision would be crisp for a little while, and then it would blur to the point where it felt like I wasn’t wearing corrective lenses at all (I have high astigmatism, 5 diopters in each eye). It would go away after about 10-20 seconds, but it happened a few more times after that. After the first 2 hours, it stopped altogether.
I put my glasses on for school, but I have my contacts in right now and they are blurring up again.. is it just my eye getting used to the lens because of my high prescription? I know I put the right ones in the right eyes.
