The eye focuses light. Formally, this transforms incoming photons so that their position on the retina is a smooth function of their direction. Diffraction and atmosphere mean a laser will be distributed somewhat in position, so the incoming photons may be spread over a 2mm spot on the front of the eye. However, all of those photons have almost identical direction and end up being concentrated in a single spot on the retina, up to the limits of the eye's optics. 20/20 human vision can resolve down to about .02 of a degree so a point source should be very similar to a .02 degree circle, the visual nerve blind spot is 7.5 degrees wide and is caused by a 1.5mm obstruction on the retina, so a point source like a laser should land in a spot on the retina about .005mm across. 2mm diameter / .005mm diameter is 400 and area is proportional to the square, so this would be something like 160,000x decrease in area with equivalent increase in intensity. Result: Not even enough to warm your skin up but instantly boils a bit of your retina.

(I'm rather happy with how well my estimate corresponds to the figure from Wikipedia: "The eye focuses visible and near-infrared light onto the retina. A laser beam can be focused to an intensity on the retina which may be up to 200,000 times higher than at the point where the laser beam enters the eye.")
