Age and 3D glasses or You too can have stereoscopic glasses..
I just realized something. My new glasses give 2D images a 3D quality.
One downside of my constant computer use is the damage it has done to my eyes. The first time I had problems with my eyes and vision induced headaches was back in college. I was leading a team of drafters drawing floor plans for grocery store end caps. It was a subcontracting gig. We’d get large piles of hand done drawings, done on grid paper. The team would convert the drawings into AutoCAD drawings. My job was to hand-out the daily work items and validate the results. So I spent hours hunched over drawings, comparing line drawings printed from AutoCAD against the hand-drawn field drawings. My eyes suffered.
Fast-forward 20+ years. (Has it really been that long?)
My new glasses have prisms to correct an overlay problem in my brain. My eye balls move just fine. I can track an object in all normal directions with my eye doing all of the correct physical movements. The problem is with text. At about 18″ my brain stacks the text. So instead of seeing a single block of text on a flat surface, I see two blocks of text, one hovering above the other. Prisms in my glasses correct this problem. The side-effect is I now see everything stereoscopicly. I only use my glasses for computer work, so it isn’t a big deal. But it is interesting when colors appear to physically pop off the screen.
So what caused this revelation? This image: http://www.flickr.com/photos/vadimk/3348335756/ I was reading an article on WPF margins. The thumbnail caught my eye so I followed it. Her left arm looks 3D to me, when I have my glasses on. It appears to be hovering above the screen, ever so slightly.
Interesting. My headaches are gone and my days go much smoother as a result, so I see no need to change my Rx.
Anyone else notice this issue?
