There are consumer camcorders that can see 1920x1080, such as Sony HDR-HC1 and Canon HV10 & HV20, but they can only record to 1440x1080i. Optics are a limiting factor because of the low cost, as well as the fact that they, like a lot of inexpensive cameras & camcorders, are using the Beyer matrix, each pixel is only one color, so you can get odd moir effects too. HV20 can output in 1920x1080p, but you need to capture it directly over the HDMI link rather than record to tape.
I fail to see how the optics need to be much more resolving in resolution than the prescription glasses. If the prescription glasses were not capable of allowing me to see 1000-1100 line pairs then there is a problem.
Also, notice the 1440 instead of 1920 is on the horizontal, because this is the direction the human vision is less sensitive. Evidently, the common human isn't as sensitive to losing +25% resolution on one axis, but is very sensitive losing the same percentage on the other axis.
