But I agree, completely unreasonable number, mostly because there's no way these are going to be used by non-third world country inhabitants (I'm guessing they've got no famous designers on board), not everyone who needs vision correction wears glasses (contacts, laser eye surgery, bumping into a lot of stuff), and of course, the big one: not every person in the world needs their vision corrected!]]>Dec 23rd 2008 8:08AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/Dec 23rd 2008 11:45PMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/

It makes a massive difference in being able to fine tune them. the syringes can also be detached now after the glasses are set.

The lenses aren't as good as real glass ones, but it's pretty surprising how well they work and how cheap they can be manufactured. It's also great when you realise they can be adjusted/shared/reused unlike a set prescription.]]>Dec 23rd 2008 7:50AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/Dec 23rd 2008 2:30PMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.guardian.co.uk/society/2008/dec/22/diy-adjustable-glasses-josh-silver .

Opticians make ridiculous margins, as I learnt while purchasing a pair of glasses for around £250. The cost of the lenses to them? £2.50.

1) how a person will be able to check if that tuning is the best for them?

2) Isn't true that some vision ailments are only corrected by a format-specific lenses?

How durable are these lenses though? If you scratch them do or drop them does the silicone leak out?
What if the lenses start to sag? They are liquid after all, and would most likely bulge nearer the bottom especially with time.
How do you correct for astigmatism? I doubt that you can actually.]]>Dec 24th 2008 8:43AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/

1./ The same way your highly trained and highly paid opthalmologist does: by twiddling the knob on the side of the spectacles until your view gets better-better-better-better-best-worse-oops, and then going back a little way.

For simple lens prescriptions with no serious underlying medical problem, it's a very simple process.

2./ Yes. Opthalmologists earn their money by prescribing complex (non-spherical) lenses where necessary, and by diagnosing other diseases.]]>Dec 23rd 2008 8:23AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/Dec 23rd 2008 8:23AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/Dec 23rd 2008 8:41AMhttp://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/http://www.engadget.com/2008/12/23/british-physics-professor-perfects-tunable-eyeglasses-no-ey/
Go read the Dune books, they used oil-filled lenses in an imaginary world that was, come to think of it, based on our far future.
