Dale,
Your eyes are key to your livelyhood and allow you to provide for your family, don't take any chances with them by guessing, find a reputable eye doctor and have an eye exam. Research the gizzards out of any corrective procedure before doing anything.
Remember, just as in any discipline, not everyone graduated at the top of their class. I experienced the same thing at 43, seemingly overnight. I grew up with glasses for long distance correction, then went to contact lenses, and three years ago had lasik surgery.
My vision is now 20/16 in both eyes, but am wearing prescription reading glasses as I sit and type. Forget the dime store reading glasses and get good ones ground for your eyes and tasks. As an aircraft engineer I have a set ground for 20" from my computer graphics screen, I have another set for my hobbies that are optimal at 12". I also rehab older buildings and have safety glasses that are bifocals, uncorrected on top and ground for tape measure reading on bottom. By the way, when you first get bi or tri focal lenses, be very careful going down steps! Good luck and welcome to the old guy club. There is one more thing that degrades with age, but I can't remember what it was .....
