You've got nothing to worry about then with the blurriness.
I've got it so bad sometimes that when I blink my contact completely shifts off center.
When you put them in, close your eye for a few seconds and look around in all directions, and then open your eye. this should help with that.
As for the night thing it's really probably just different pupil dilation, it's nothing to worry about really.
If darkness effects that right eye in that manner, just say your pupil is more dialated then your left eye....When you'd go out in the sunlight your right eye would be more effected than your left eye.
SInce you had said you've had an eye appointment 9 months ago, you're about due for another one, which they will check pupil dilation.
If nothing else just call the your eye care optical center and ask the receptionist. usually if it's common they should let you know about it.
