Anyone got explanations for these?

We don't know what causes those things, therefore god exists.

But just in case you might get an ophthalmologist to look at the this

Another thing is when I look at a straight line I can get my eyes to sort of glide along the line if I go from left to right, but my eyes won't glide smoothly along the line from right to left.

I sounds like an oculomotor dysfunction, meaning your eyes don't track properly.
