I've been playing around with this a bit without benefit of a DVD because I noticed over the last year or so that the print in magazines, books, and newspapers along with the numbers on those little fuses on PLC outputs just aren't as large and clear as they used to be.
I alternate between trying to focus on something close in and then on something at a distance. I think it may be helping, but I probably should do it several times a day.
I bought a couple pairs of those cheap reading glasses, +1.25 and +1.50 magnification, and they do make small print look like it did years ago. But when I take them off, I notice fine print is blurrier than when I first put them on, so I worry that they are like a crutch that one could become entirely dependant upon.
Since muscles in our eyes vary the curvature of the lens for near and far sighted vision, it makes sense that strengthening those muscles would be beneficial. And it seems artifically assisting those muscles may make them lazy. Someone with a vested interest in selling corrective lenses may disagree. I'd like to see a comparison of vision testing of 75 year old Americans vs. 75 year old Aboriginees who never saw eyeglasses.
No, I AM NOT squinting as I type this. Always think positive!
