I appreciate the simplicity and design rigor of the approach, Choppergirl, though many will tell you that digital readouts without any analog indication are slower to scan and interpret. You have the know the limits in your head (or have them printed next to the LCD) and do the math. Not a problem for compass or altimeter but definitely an issue for the engine functions and airspeed. One way to solve your labeling issue would be to use larger-size LED or LCD or OLED matrices. A larger six-digit seven-segment or alphanumeric display would allow you to have a three-letter prefix to identify each digital readout. Even without moving to graphic displays where you control every pixel, 16 x 2 character displays would provide much greater clarity in presenting information. For example, I have seen a number of examples of folks making oversized digits on a 16 x 2 display, usually just to make big numbers, by using character tiles. Similarly, you can use a few custom characters to create bar graph tiles, with the bar flashing if out of limits. If your oversize numbers are the 3 x 2 variety, then that would leave you with a 7 x 2 display for labeling and the bar graph. If they are the 2 x 2 variety then you've got 10 x 2 leftover. Leaving one blank space for clarity, you could still have "ASIKTS" and a six-character bar graph or "ASI KTS" and a 9-character bar graph in front of your oversized three-digit display. The bar graph could be something as simple as a bar that grows left to right or a fixed horizontal bar with a vertical line that moves left and right. The nice thing about his approach is that you are still only sending character sets to the the controller, so there is not as much drain on the processor as if you were addressing individual pixels. Of course, once you start doing this for several functions indicators, you may find that the multiplicity of separate displays and wires, while giving a great retro look, are actually a lot more trouble and more cost then driving an single display. Something like this monochrome 128 x 32 OLED display would allow you to display six double-height, three-digit indications with smaller labels and bar graphs all in one 2.5 x 1.1" package controlled by four or five wires from one Arduino controller. On the glasses, since I am blind as the proverbial bat without mind and don't like contacts, I suggest something like these -- http://www.bobster.com/spektrax-convertible-3-sets-of-lenses-prescription-insert.aspx -- for open-cockpit flying though there are of course many more styles to choose from in the motorcycle world.
