As you get older the eyeballs and in particular the cornea get harder & flatter so your distance vision gets better and your close vision gets worse.
I have 2 pairs of general use bifocals and 5 pairs of specific purpose glasses .
Drove the optomistrist crazy but he finally wrote me out perscriptions for
Very Close
Reading
Short intermediate
Long intermediate
distance
Then I bumped around the workshop for a week with a 40" rule in my hand to work out the distance I like to work from things and how good a focus I need at particular lengths.
Prior to doing this I had at least a dozen magnifing glasses all over he shop + a magnifier/lamp at the grinding wheels, chain maker, chain grinder, press, lathes, mills & welding bench.
What I spent in glasses I will save in electricity.
Should have done this years ago but it sort of sneeks up on you.
LOL! That's funny on one hand, sad on the other. Sad in that we've aged to this point but eyesight issues could've happened at younger age and things could easily be worse. I keep cheaters in both garages, bathroom (the library,) my end table and in my truck. I'm kinda like the alcoholic who stashes bottles everywhere. Ahhhh yes, it's all part of the "Golden Years." I remember growing up listening to older folks talk about that and I couldn't wait. Well, I made it and imo, so far, it SUCKS. I'll admit it does increase the number of new friends you get to make ie: doctors, nurses, tech's and so forth AND you get to contribute $$$ to the coffers of drug companies due to the increase in med's your put on which in turn helps the economy. Words I've grown to live by come from the old DuPont motto, "Better Living Through Chemistry." I don't know that's it living, but it'll do I suppose. Seven pills in the morning, seven at night. The 25th I'll have my gall bladder removed because the three doctors don't know what else to do. Seriously, in this day/age they don't know. There are no more tests they can do. I get bile in my throat, pain in the pit of my stomach, nausea, and it's been going on for eleven months. Eight different tests show everything is good, even the GB but reading online, every symptom I have points to that. This is one reason it's taken me so long on the mower. I've good days, I've bad days, with the bad being more frequent. Golden Years. Ha!
