That there stereoscopic moovan viewing trick is very similar to the eye exercise I was shown, so you don't have to wear glasses when your eyes get a bit lazy.
Apparently by forcing the focus muscles to work harder you can get your eyes to 'sharpen up' .
The Brain also gets a workout as it gets lazy with the processing.
Got to be done regularly apparently and doesn't fix all eye conditions.
The alternative is glasses, which fix the problem for a while and allow your eye muscles / brain to get even lazier so after a few years the lenses have to get a bit thicker .....
I use the Winston Churchill 'salute' at about 0.5 m and work to get the third finger visible. Then try to hold the image for a while. Well what else is there to do during those long hot baths ?
Ive been able to get very short term vision improvements by doing this.
Could briefly read writing at a distance that's normally blurred, after doing a bit of finger watching.
I wont change to staring at moovan cos its quite a lot harder to pull the images together at the approx 0.8m distance to my monitor.
With regards to the shopsoiled blade of doom, could it be shortened and re-drilled, then have a lightweight winglet added, ideally with its mate getting similar treatment ?
A nice sandwich of reinforcing material around the root area would be even better.
Then theres the possibility of chemical 'hardening', and I may have something that could help
like conkers dipped in vinegar then baked .....
