| 1279120 | 2012-06-02 13:23:00 | How can it be a great choice b4 we know the outcome? Because I am currently on my 4th set of glasses from this supplier - that's how :) |

| 1279124 | 2012-06-02 23:19:00 | There's some weird science going on with materials that have a negative refractive index (traditionally impossible). If they could sandwich a regular lens with a negative index lens the result could be a lens that looks flat and has half the edge thickness, but still providing the same strength overall, and possibly with improved optical properties. Don't hold your breath on ever seeing them in production. They'll be used in computers long before they get used for eyewear, if they ever get used at all. |

So, I wonder what happens to the speed of light with negative refractive index. If the velocity of light is now negative, does that mean you see yourself returning before you have left ? :) :illogical |

I don't have that, and I sit in front of a screen all day but it doesn't bother my eyes. On the other hand I do have rather major astigmatism, I've been told it will never affect me. |

| 1279128 | 2012-06-03 05:36:00 | PCTek, this is a bit late seeing as you have ordered the specs, but I too have asymmetrical lens thicknesses - much thicker on the right. I've never been particularly conscious of the difference, either while looking through them or AFAIK from other people noticing them. I have metal thin-rimmed frames, so the extra thickness is obvious if you are looking, but as I said, I've never seen it (ha ha) as a problem in all the 60-odd years I've been wearing specs. | Tony (4941) | ||
