"Liquid Lens" fluid (ad on TV) does it work?
just wondering if anyone here has tried this stuff and if
you like it(?). they show a fairly non-typical scenario of scratching a lense w/240 grit paper and then using the fluid. i wonder how it would work on typical scratches and how long it lasts. does it attract/repel dirt? thanks! --Loren |

The scratches seem to disappear. That's all the commercial is showing. |

There is more to removing scratches from plastic or glasss than merely wiping on a fluid (at least in this present stage of time). We used to work our butts off polishing out scratches on aircraft transparencys with some really ultra fine abrasive media that felt more like silk than abrasive, and it was tough, and usually when you did get it looking good, you always wound up with some distortion in the repaired area.

If it's a lens, you will change the curvature. If it's a window, you will introduce curvature. I don't know the product in question, but I do know that low-cost mobile windshield repair is done by filling the cracks with a resin which has the same index of refraction as the glass. If you could fill the scratches in a lens with this same material, and get it exactly level with the glass, it ought to work |

The scratches seem to disappear. That's all the commercial is showing. Not exactly. Water would bead on a lens due to its surface tension. If you added a surfactant( like soap) to break the surface tension, it would leave a film. What they're showing is a polymer that fills the scratches with a fluid that hardens to a refractive index similar to polycarbonate lenses which are what is predominantly used in todays glasses, not GLASS, unless you buy that type of lens. Still, the polymer would work to a point. Nothing is a perfect solution. In time it would probably have to be reapplied.

brought forth from the murky depths: What they're showing is a polymer that fills the scratches with a fluid that hardens to a refractive index similar to polycarbonate lenses which are what is predominantly used in todays glasses, not GLASS, unless you buy that type of lens. Still, the polymer would work to a point. Nothing is a perfect solution. In time it would probably have to be reapplied. No, Lexan (polycarbonate) is 2x the cost of standard (hard resin) plastic lenses so the high-index is the usual material, not Lexan. I found that regular old Rain-X works well to fill small pits and scratches in my windshield so I tried it on my safety goggles with some success. It filled in some of the scuffing which improved vision through them, but they were too old and abused to be used daily. They're perfect for backups and bystanders, though. Chemistry folks. Economics, folks. - Yea, though I walk through the valley of Minwax, I shall stain no Cherry. http://diversify.com |

And anyone who gets a polycarb lens without the quartz coating is wasting their money. My quartz-filmed polycarb lenses are incredibly resistant to scratching -- far more so than my old glass lenses were. The onlty marks on the lenses I'm wearing now (after about 8 years of constant use) are the nicks and pock-marks produced by chips that have flown out of the lathe or from the grinder when I've been working. Yes, I use these glases as safety glasses -- which is why I stick with the incredibly unfashionable large frame and lenses that drive my wife crazy. A do use a full-face shield when doing the really dangerous stuff though. -- you can contact me via http://aardvark.co.nz/contact/ |

This works nicely.
Take some glycerine soap... the kind you can see through. Rub the bar on your clean lens... just make a letter "O". Polish it in with a clean cotton cloth. Scratches gone... not forever, but certainly for the day. Repeat the next morning. S Ernie Leimkuhler wrote in message ...

The liquid lens commercial is full of crap, look at the rim around the
lenses, its powder they put on there and then wipped it away with a dab of water and cotton. |
