I have the Canon 10X30 IS and they are great. They are small, reasonably light weight, the batteries last a long time, easy to use and work. They help in reading markers and can also be used at night for star gazing. They stabilize based on accelerometers in the unit and (I believe) have liquid adjusting prisms that respond quickly to any motion. I am 64 and find them very useful in these applications.
A night vision system would also seem to be very useful. The technology is pretty mature, so I would not be concerned about that, but you should find a store where you can try them out and satisfy yourself they are comfortable to use.
