Manufacturing our own spectacles?

You have misinterpreted the start of a technical discussion to investigate possibilities as though it were a definite commitment.

I refer you to my other post re £240 cost.

The rumors abound that FDR was actually assasinated by a Nazi assassin, a shot to the head.

Couldnt have happened to a nicer guy.

"Upon Roosevelt's death in 1945, H. L. Mencken predicted in his diary that Roosevelt would be remembered as a great president, "maybe even alongside Washington and Lincoln," opining that Roosevelt "had every quality that morons esteem in their heroes.""

This sounds about right.

I've seen the plastic blanks where I get glasses, they're very large disks.

It's interesting how hard it is to get real glass lenses these days. My optometrist is badass and sells them if you ask without any bullshit about why you don't want them. They were only $10 more than plastic.

Every other place says they're "illegal", "obsolete", or "cost too much". They're all full of shit.

My bifocals cost around £80 - 90 per pair and that is before frames and non-glare coating etc.

That is what it sounded like.

How do they stand up to flying bits of metal? When I worked in chemical manufacturing the H&S gestapo made us wear proper safety glasses, but I could never see owt through them, so I was more at risk from tripping over my feet with the safety specs on than I ever was from getting debris past my street glasses. Mind you, according to the data sheets, the safety specs would be great if your employer was in the habit of firing ball bearings at you. Well, so long as he only aimed at your eyes.

I collect my swanky S&B Model A from Peterborough on Saturday. With such a posh bit of kit I couldn't possibly wear other than haute couture designer glasses frames.

You might find this interesting:

"Saul Griffith's vision may help millions of people see better.

The Media Lab graduate student has invented a machine to make low-cost prescription eyeglass lenses for people in the developing world who can't afford them now.

The portable device, about the size of a snare drum, has a programmable mold that forms an acrylic lens in the exact shape prescribed by an optometrist."

Have you looked at the numerous online spectacle services? Varifocals are dearer than single focus lenses but there is absolutely no need to pay £240. Glasses are normally posted in a few days and are made in UK with a huge choice of frames.

I dropped my glass Zeni bifocals over the weekend. Landed face down on a piece of steel plate, and the grind line for one bifocal split all the way across. Still usable, still snug in the frame. Plastic wouldnt have done that.

absolutely

Bob,

I've not found any online sources of plastic varifocals with astigmatism correction and reactolight features - do you know of one? My last pair cost a packet from Boots and it's really time for a new prescription - I'd just love to have the eye test then walk out with the prescription !

Plastic would not have cracked, or offered you a clear high quality optics that don't yellow or scratch?

Wearing a cracked lense sounds likes a bad idea. If something hit it again, you're getting already broken glass to the face.

Both.

Ayup..these are going to be replaced. Most of the time I can get along fine without glasses I can pass the DMV reading tests without them,..but..sigh..as I get old..my arms are getting shorter....

These were actually screw ups..when I had the tester do his thing, I thought we had properly speced the close up lens grind, but the far side is almost good enough to read the speedometer on the truck, and the close up is only good for about 14" from my nose. When I get the money to go back to the eye tester, Ill have a better idea of where to go on vision ranges.

Zenni will get the new perscription. Probably 1 pairs of single vision, ' and 1 bifocal, modified for proper close up, And bigger lenses. The ones I have are pretty small and the bifocal grind line is right smack in the middle of the crosshairs/peepsight when I get a good stock weld.

Last set of glasses I got I religiously filled in the form on the web sight entered SK11 9DL.for the prescription

They rang me back a couple of hours later to query it as the prescription was the post code for Jodrell Bank

Have there been any updates on this article from 2002? Did he ever do it?

Norm -being re-spectacle

Mine witters on: "No, they're not 'Plastic'! They're 'Resin' ". Ooh! Ooh! I'm so lucky! I've got Resin, not cheap crappy plastic! No wonder they cost so much! It must be to cover all the money they spend coming up with spin like that! Nope, I'm going to try

next time. The only problem is that an eye test doesn't give you the intra ocular distance and in Boots, at least, they refused to give me it even when I asked nicely. Pressed the Ophthalmologist said that her "employer had the right to protect their business". I thanked her for her honesty. How do you measure intra ocular distance? I think it has to be done for viewing at a particular distance as the pupils get closer as the viewed object gets close.

Best way is just to send a pair of your backup specs to:

They measure the intra ocular from your old lenses and can even put new lenses into your existing frames.

I just put an order in for my third pair from these people. I am just another Happy Customer.

Either:-

1) Look into the distance while your significant other measures it with your best pair of calipers. 2) Look at your nose in the mirror from a bit under a foot, measure for yourself, then add about 3mm/1/8" (which is about what gets taken off for reading glasses).
