Didn't quite know where to post this ... has anyone heard of the new contact lenses that you wear at night and then you can see properly the next day without prescription glasses/lenses (I think it was on this morning).
Do they work ???

For more on marking an answer as the "Best Answer", please visit our FAQ.unless you were wearing the contact lens' the next day it would not work. if a person needs lens' it is because their own lens in the eyeball are mishapen. a contact lens works by bending the light entering the eye enough to correct for the wearers visual impairment. hence no lens in eye: no normal sight.
laser surgery does not affect the lens but 'polishes' the back of the actual eyeball to improve sight.
This was also in The Times several weeks ago. As others have explained, mastadon is wrong, because these are a "type" of contact lens that work to correct the eye, rather than bend the light.
My personal view was that a user would still have a pair of lenses that need to be taken in once in every 24 hour period, and taken out in the same 24 period too. They still need to be cleaned and stored correctly. In fact, the only difference seems to be if you're very much into sport, especially swimming.
It seems a heck of a lot safer than laser though!
PS - We're not morons and we understand that according to a TECHNICAL physics definition, a lens is something that refracts light - here - but the device is being marketed as a lens, as, all the wearer need be concerned with, is the fact that it is put in and taken out in a similar way to using a contact lens.
Do you concede that yor first answer was wrong, and that you presented as fact something that was wrong, because you hadn't checked out the story?
I'm sure you will - you're obviously knowledgeable and quite smart too. :-)
But it has been marketed as a lens and it called a lens. Your answer purported to be fact claiming that a product doesn't work. The product may well work, and I believe has been proven to work. If you had answered to quickly in a televised debate, without bothering to even check what you were talking about, then you could be sued.
I'm just saying that if you're going to state something as gospel on here, it might be good to check your facts. The product in question in called a lens, and it works to temporarily correct the sight, by a technique that does not involve bending light. Can't you accept that (preferably without using 3 separate posts to do so)?
