Eyesight problems

I need glasses for all normal walking about things, but can read and see very small stuff without aid. Welding ,or any work under a car is hopeless, take them off to see detail, can't find the way out, roll onto glasses. I don't have a solution yet but a good light makes all the difference, the new LEDs are very good, might be to do with the wavelength/colour. Keep old glasses for work, new ones for driving etc. Will keep checking for any ideas.

I liked Marks comments of magnifier on the welding helmet cartridge.

As I have a cheap headband magnifier with some spares a lens was cut to length to fit the welding cartridge and taped on.

It looks good my vision has improved of the job.

Next is to do some test Tig welds at the weekend.

Thanks to the forum for another door has opened.

If you have a problem someone might have an answer if you ask.

A skilled engineer showed me the other week how to centralise hexagon bar in a 4 jaw self-centring chuck which was so quick and easy to do.

Something I thought you could not do with that type of chuck.

Easy, just think about a coincident square and hexagon......

There is a product currently being advertised in the USA called Superfocus. Basically, it is a pair of eyeglasses that can be focused by adjusting a slider on the bridge between the lenses. They aren't cheap, but in theory they are a whole lot better than bifocals, trifocals, varifocals, or multiple pairs of glasses. They are also not too stylish - unless you are into the John Lennon look.

These are something I intend to give a try for my next pair of glasses, but right now the only Canadian retailer wants an additional $200 per pair, so I'll have to get the prescription and order from the US.

The comments about light are good. bright light=small pupil the smaller the pupil the greater your depth of field (think pinhole camera with huge depth of field and no lens - but needs lots of light!)

So start by making sure you have plenty of light - I have three 4' fluorescent tubes plus an anglepoise and a halogen desk lamp I point at what I'm working on.

I see no one has mentioned laser correction. I wore glasses from 14, now 67. Short sight.

A couple of years ago I had 1 eye done. I can only say what a fantastic investment. So 1 eye is short sight still and the other is now normal vision. I can now see a bus number at 2.5 ish city blocks away. And sight only gets a bit blurred when, say, looking at mm divisions on a rule. 10 seconds work, a couple of days slight discomfort. No glasses under the welding shield. No smearing in rain. Pop crash helmet on.

Well worth investigation. In fact, I would go so far as to say if it had been available when I was young, it would possibly have changed my lifes direction. Sound like an evangelist, don't I.

My friend and I both have eye problems and spent many hours at the eye clinic.

Barbara had Macular Degeneration myself a field of vision fault caused by an injury in my motorcycle days.

Of the sight aids shown a white light lamp was the most useful and at that time Argos was selling them at reduced price.

For reading it was money well spent.

I now have many similar lamps in my workshop and they are good for Tig welding and detail work.

Hi Ken,

I'm surprised you seem to have plenty of accomodation after the laser surgery ... do you need reading glasses?
