It wasn't all that long ago that one day out of the blue I noticed I couldn't read anything on my computer screen below the largest of text.....so after a few days of this I did the same as the rest of ya....Hit up Wallyworld and got me a pair of reading glasses. they helped alot but the real fine detailed stuff still wasn't there....my airbrushing was suffering badly so for the first time in my life I went to the eye doctor to see what was up.....he just laughed and "Boy...ya done went and got old".....He proceded to expain that for most of us once we hit our 40's are eye's start changing and problems with our vision become alot more noticable, and before I walked out of his office I had a prescription for glasses....Bi-focals of all things....man I feel like a grandpa using these dang things....I hate'em with a passion....but whatcha gonna do??
I was at a pinstripers panel jam in Houston awhile back and met up with an old time striper that saw I was struggling to see thru the durn little bi-focal part of my glasses, and he showed me where he had two pairs of glasses....one regular and one is made with just the bi-focal part which is what he wears when he's pinstriping, so I guess thats the next pair i'll buy....jeez it sux gettin old....lol....but its nice to know i'm not the only one.
One other thing I learned recently....our eyes are muscles, not organs....they need to rest periodicly just like any other muscle, so when your painting all your finest details stop every so often and look at objects far off...or just close them and let them rest cause your straining them when your focused on tiny details and like any strained muscle they get fatigued and benefit from taking short breaks occasionally.
Who knew??
