Temporarily Blurred Vision

Occasionally my vision becomes blurry, however if I blink or even just look at something else or at least make my eye focus on a different area my vision is back to normal. Why is this happening? What should i do about it?

Blurred vision that clears with a blink generally indicates problems on the surface of the cornea: dry eye, mucous in tear film.
