I have a fairly cheap green laser pointer that produces a fairly big spot of light (actually two spots most of the time!). I'd guess the size of the spot is about 1/100th of the distance from the end of the pointer to the surface it hits (e.g. after 1 metre the size is approximately 1 cm).
If the pointer is steady and I sit still I see a pattern of sparkly light (on the wall, table top, etc.). Although it sparkles, each tiny point stays in the same spot within the circle of laser light. If I move my head left or right the pattern moves with me but disappears at the edge of the spot, while a "new" part of the pattern appears on the other edge. What causes this effect?
I wear contact lenses and I've noticed exactly the same thing whether I'm wearing them or not, no matter the distance. Because each point emitted by the laser should be a true point source it should not be possible for it to appear blurry. My personal observations agree with this.
