Automated squinting instead of glasses, contacts, or lasik

[Lee] is nearsighted and has had it with contacts and glasses. When trying to figure out an alternative, he looked at the core of the problem. The eye is not shaped correctly and therefore cannot focus adequately. The solution is to change the shape of the lens. This is exactly what lasik (laser eye surgery) does, but instead of going under the incredibly bright knife [Lee] built some headgear that pulls on your face to reshape your eye.
The hardware is from an old portable CD player. The sled that moved the laser lens has been repurposed to pull a thread taped to the skin at the corner of his eye. He built a control system that lets him adjust the tension by moving his fingers. Basically when the skin is pulled tight it causes him to squint and possibly reshapes the cornea just a bit. We’re not sold on the idea, but we can’t poo-poo the experiment; who knows what discovery this could lead to? We’re just glad he didn’t use electrical impulses to hack his peepers.
You can find some test video embedded after the break.
I use CRT lenses.

They are hard lenses you wear at night while you sleep which reshape your corneas. Then you don't need to wear anything during the day but you have perfect vision. I've been a soft contacts (and glasses) wearer for years and don't trust the surgery options. These work great and they are totally reversible. Stop wearing them and your eyes return to normal. I wish I had known about them sooner.
