Simply allow your vanity to be outweighed by your curiousity....get yer speccies. I got mine design built for looking at the instrument panels....but at the cost of fussing with the quack each time I take a medical. The focal length of the panel exceeds the 18 cm reading standard thus it becomes a hassle each medical when I have to extend my arms to read. It works great in the cockpit. The overhead panel is another problem...have seen guys with special built glasses with "bi-focal" lenses on both bottom and top of the lens....I have even seen guys take their glasses off..turn them upside down....to read the upper panel. I prefer the "Brail" method for that...but then I only fly aircraft that do not require any switches to be thrown on the upper panel except at start and shutdown.
For sunglasses...I had the Optomertrist tint a regular pair of glasses.....with bifocals...works great....and cheaper than special purchase sunglasses.
The only real problem I have now is finding a way to fit my Seeing Eye Dog into the Jetranger....the Huey is no problem. Longline work is a real exercise....finding a cane long enough is a chore.
