Magnifiers.
« on: January 10, 2013, 01:10:01 PM »

Some advice requested here…
I’m now at the stage where I need some sort of magnifier to allow “work” to continue.
As far as I’m aware these fall into 2 categories. The “Anglepoise type and the sort that straps to ones head.I’m sure many Mayhemmers use such devices so I’d appreciate some comments about the pros and cons of each type, and (if possible) the “best buy”. Thanks in advance. BY.

I 'took over' from my wife an anglepoise type with a daylight bulb. She bought it for embroidery but doesn't use it. I have used it a couple of times but find that getting the distances right is not always easy. That is head to magnifier and magnifier to work piece distance.

Both have their advantages and disadvantages, I have the anglepoise type as I tried the "goggle" type and found them to be uncomfortable and gave me headaches.


The Angle poise types are better, but some times its not possible to get the magnifier bit exactly where you need it

I have a table lamp style. With a ring light built in.
It has two lenses. A main lens, of about 3x magnification, and a very small lens (x10) ground into the larger lens. I have found both useful. By moving my head around the lens, rather than trying to position the lens, I can do all that I need to.
You can also sit back when you need to without the world going out of focus, and feeling dizzy. As would happen with specs.

I also found a third hand helped. One of those little stands with crock clips, and locking forceps also help a lot. That way I have a hand free to steady myself and manipulate the lens.

The lamp styles should have a lens cover. I read somewhere that there is a fire risk if you leave them sitting in the window on a sunny day, with not cover.

I have an an illuminated angle poise type that I don't use any more since I found 'reading' glasses on sale in the local the Pound Shops!!
They come in magnifications from x1 to x4 in x1/2 steps and are much more convenient to use. I have several pairs dotted about the workshop in several magnifications and find them invaluable. When they get to scratched, paint on or broken no problem, just buy a new pair.

I have to admit I laughed when I read that warning in the instructions, but on reflection its a valid concern


I think to be honest its horses for courses and what you feel is most comfortable for you


As for the visor things I had an optivisor, while very good, just wasn't for me

Agree with Barry,
 
I find mine very useful, but fiddling with distances does take a bit of getting used to!

Hi Bryan
One size doesn't fit all. I have an angle poise Led with X3 mag £40 that is great for the bench once the beeping thing is set up. I also have a cracking rechargeable headlamp with focusable light and variable intensity for the awkward stuff where you need to move your head a lot. Next visit to the opticians I am going to get some glasses specifically for modeling and set to a closer focus. That way the headlamp will be even better. On reflection I use the headlamp most.
I also need to improve the general lighting in my shed.

I now need glasses to read and I use the off the shelf ones 'ready readers' the supermarket.
I found you can buy up to +3.5 which are very strong! 
 
Glasses are very light to wear, unintrusive & cheapish...

I can't get on with magnifiers either. Like Martin I have some cheap reading glasses that do nicely. I find 2.5 or 3 about right. Take a sample of your work with you when you go shopping for them so you get a proper idea.

So far, so good.
Did I mention that I have ARMD in one eye? That means I have very little binocular vision.
Looking at some of the web-sites I see stuff ranging from around £20 to well over £1,000!
The really big problem is trying to find a place where I can try some of these offerings. I'd feel a bit miffed if I bought something from an advertising blurb only to find it totally unsuitable.
I can understand the "dizziness" effect that can occur with the head-mounted things, but some have "flip-up" lenses....doesn't the use of these make dizziness less likely?
Also, many of the offerings (cheap to expensive) crow about the LED "white" lights. All the so-called "white" ones I've seen are really more blue than white.
Still confused! Please keep up the comments....good or bad. Thanks a lot. BY.

Bryan,


The blue bulbs are to correct the naturally rather warm tones of an incandescent bulb. I don't think they give the object a blue tone, just a more accurate representation of daylight. Some white LEDs are OK, some are very blue. I believe you can get them in tones ranging from warm white to blue white.

I think the colour of light is a bit of an irrelevance. The range of light we work in everyday, without our brain noticing,  is pretty varied. As long as you are not working in shadow.


The cheapest ones that look like a table lamp and have a swan neck that bends have only one potential flaw. If the base is too small, they can be top heavy and fall over when fully bent over. Others are OK, but anglepoise may be better. Some angle poise have a base, others screw to a shelf.


LED can use less energy, but if they cost a grand???


Most on Amazon are under 50 quid. Looking at most of those at the upper end should do the job.
There is even a 3-in-1. Floor stand/table stand/table clamp for under 50.

Gentlemen may I please PLEAD with you to go to a QUALIFIED OPTICIAN and NOT self diagnose in the local supermarket.
 
You only have ONE PAIR OF EYES....if you feel the need to use a set of supermarket glasses then you will not doubt need PROPER PRESPICTION glasses.....OH also you might THINK you just need them for reading....How about DRIVING.
 
I have a problem with work regarding welding and when I questioned my Optician about a different pair he was able to mask eme some up for the distances involved.....If he had said No then I would have flipped....why may you ask..........
 
 
WELL FATHER WAS AN OPTICIAN............SO TAKE IT FROM ME GO AND GET YOU EYES TESTED

Totally agree Dave
Getting a pair of high power pouns shop glasses
with cheap distorted lenses will in time get your
eye muscles used to working that way
Talk to an optician about what the problem is and
take hia advice

I have 3 pairs of glasses, a pair for normal use / driving, a pair for reading and a third pair between the two for vdu work (computers) these I can just about watch tv with too so sat at home they are my everyday glasses.
if I need to do close (really tiny detailed) work I wear my reading glasses over my vdu or outdoor glasses, this brings the work to about 3" from my eyes in microscopic detail (with the added bonus that it corrects for each eye separately (my two eyes are nearly 2 dioptres different), but it does the job.
but I agree do get a test from an optition (it may be that once you get a prescription you can fill it from the rack of reading glasses - but if you have any astigmatisms which need correcting you will need an optician to build in the corrections.

sorry to take it off topic but I also agree with Dave I went to the optician as I was having trouble reading my work instruments they gave me a simple prescrition but more importantly they found a problem with pressures which I may never Have known about unltill it was much more serious glad to say that a simple op, all is now well, a check up is so worth it

Dave, the suggestion of glasses it's not meant as a sub for prescription glasses. These are effectively just a pair of magnifying lenses in a frame - it's no different in principle from using a magnifier on a stalk, just a darned sight more convenient.

But yes most people 'our' age should get an eye test regardless.

SORRY but you are SO SO WRONG in what you are saying,these are proper glasses not magnifing ones,a Magnifier that you buy varies in focal length for differnt people,what I mean here is that the distance of foccusing for you is differnt to eg Martin.
 
Now the glasses that are for sale in supermarkets etc etc as someone has allready pointed out have no diopters in them,some people need prisms,each eye is different from person to person.Each eye can differ immensly,some have long vision others have short sight.Some people have a clear lens one side and prescription on the other.
 
How can you tell if you have a cataract,glucoma etc etc etc
 
So with this in mind how can you SAFELY say by going to a supermarket and choosing a pair of glasses they are RIGHT for you.........WELL YOU CAN NOT.
 
If it was as simple as that well every Optician in the country would have to close..............................

If anybody finds that an extra lens helps, a visit to the optician really is a good idea, if only because, as Grendel said, your eyes dont degrade at the same rate, so its quite possible to need different lenses for the different corrections needed.
As to the Anglepoise magnifier needing a cover - yes, very definitely.  Someone once left an uncovered one near a window and scorched a big mark in his workbench when the sun came round later in the day.  Thankfully, not me.

I had already decided to get prescription ones for comfort really. I am we'll aware of my eyes and problems already. Now if I was only going to pop these on for a few minutes then off the shelf would be ok (eyes already well tested) but any longer than that then you are going to be straining one eye and headaches will follow.

In my youth my eyesight was perfect for fine detail model making, but I needed glasses for distance.  Strange now that my eyes have altered so that I do not need glasses for driving etc but that kind of close up fine work is impossible.   Supermarket 3.5x magnifiers are good for threading rigging and detailing.  I do not intend to enrich opticians with hefty sums to make up special ultra close up glasses.  ie:  a focal distance of three inches.

I have an anglepoise magnifying lamp, its main use is to apply extra light to a local area and for inspection. 

For very fine detail painting there is unfortunately no real substitute foe excellent close up natural vision and a very steady hand, both which I miss greatly.

Hi All,   
   
 I have tried magnifiers, both the one that hangs around your neck and the one on a stand, but found them very restrictive in use.
 I decided to ask my optician about "model making" glasses and now have a pair that focus at about 1 foot from my eyes. 
 The glasses have transformed my hobby - no more headaches or eyestrain and I can see the fine detail better than ever.
 Absolutely wonderful and highly recommended.

  Dave.

Just picked up on this topic and I agree 100% with Dave (Stavros). You need to get your eyes sorted out with an optician BEFORE you start looking at magnifiers. As people get older, their eyesight commonly deteriorates but they are often not immediately aware of it as their brain will compensate to some extent. Unfortunately, many eyesight defects cannot be cured as such but often the condition can be stabilised. An eye test will not just test your eyesight but will also identify other conditions that may not be immediately apparent such as glaucoma. So definitely go to Specsavers!
 
I have glaucoma which runs in the family and which has affected vision in one of my eyes. It is caused by pressure building up in the eyeball which irretrievably damages the optic receptors at the back of the eye. However, it can be controlled by eyedrops which reduce the pressure and that is a small price to pay for retaining your eyesight. In the last year I have also had two cataract procedures, one eye was deteriorating quite rapidly, the other less so. The cataracts alter the focus of your eyes and restrict the amount of light getting in. Most people over 60 suffer from them to some extent. It is quite amazing just how much difference the implants have made. Everything is brighter and colours more vivid and my optician has said that with my new pair of glasses (which you have to leave until about 6 weeks after the op), my vision should be better than 20/20 which is a result by any standards. At the moment I'm getting by quite well with an old pair of glasses around 10 years old which just demonstrates what an improvement has been made. Many people don't like going to opticians and leave things too late in some cases. Very often people, especially women, refuse to wear glasses for reasons of vanity - this is a seriously stupid attitude, especially if you drive a car. Nobody else cares if you wear glasses because it is so common but people seem to think it is a big thing when it's nothing of the kind. And then there are options for contact lenses or laser treatment which can avoid the need to wear specs - but only if you have your eyes checked out first.
 
There is a lot that can be done to stabilise or remedy eye defects - but the longer you leave it the less successful it will be.
