I also use varifocals all the time and agree with Bill that looking under machines and such can be difficult, also working upside down. But a bright light certainly helps me. When I had my first ones, if I swivelled my line of view whilst looking at a straight line then the vision went all wavy. When I spoke to the optician he said some versions of glass do that, unfortunately this meant I had to move to a much better quality of glass. Only problem is that it was quite a bit more expensive, but it did cure the problem.

Colin

Hi All

I wear varifocals. I have to being quite long sighted so I need them for both short and long distances. Coated lenses are always offered as an option when you buy them. I am not sure they are so good They do scratch and when they do it is quite visible and rather distracting to look through. The last pair I ordered a couple of years back was not coated, they are no worse than the coated ones were and if anything clearer at this late stage of use. (I have been on several building sites doing design work) Lots of concrete dust. I am due for a new pair and I think I will order the same again. When they offered the last pair I was also offered a thinner lighter higher refractive index plastic lens, it was quite expensive so I declined it. That was a mistake, I had not taken into account the new prescription at the time required thicker lenses. They are very heavy, on the nose….. For the new pair I will order it for comfort.

When I got my first varifocals my biggest gripe was and is that I can no longer see vertical plumb and level within a few mm. very useful when inspecting work, before I got them it was no problem. The glasses distort the image. Very annoying. Now I need a bubble level.

Just for info. Using High Refractive Index glass means that the same power of lens can be made with less physical curvature; and that's what gives the improvement.

One thing that came up recently, my good lady suffers from really itchy eyes – turns out it is the result of arthritis. A combination of eye drops (I will get the name, readily available and very good generally) and arthritis medication has improved things no end.

Graham,

Not sure if they are the same drops but, the Hospital prescribed Celluvisc eye drops for me [active ingredient is Carmellose Sodium].

… Using these was, quite literally, a life-changing improvement.

…. and when you have the anti-reflection coating, you can't have the scratchproof coating so the lenses scratch easier.

Regarding cost and its minimisation that has been referenced s few times: I long ago decided that my eyesight, its protection and improvement was not the worse place, by far, to sink my hard-earned cash and I no longer worry too much about it. If I need it I get it.

G'day all.

Sort of on-topic – many years ago, when the ME Ex was at Seymour Hall and also at Olympia there used to be a small stand run by a chap who looked like Col. Sanders. He had a little kettle on the boil and would demonstrate the misting up of glasses and then apply his remedy …Clersite rings a bell?? He stopped attending before I did and I haven't been able to locate the product since. It certainly worked and the effect on old 'specs' was remarkable … vision just like when first supplied. The stuff was sold in a tiny round pill-box like container and pink in colour, and PRICY!. Applied by finger and thumb and polished off by tissue. I suspect it was probably jeweller's rouge mixed with a soapy 'gunge'. Anybody remember same and/or come across it lately?

I have both anti-reflection and hard coatings on my varifocals.

So do I, and they are reactolite, well, get darker in sunshine.

Don't know how that works for you. In order to work at all, the anti-reflection coating must be on the outside – i.e. on top of the anti-scratch. The AR coating is (relatively) vulnerable to scratches. Granted these scratches are not on the lens itself (which is protected by the anti-scratch coating) but on the AR they are just about as noticeable as they would be on the lens (I'm looking through one right now ).

For that reason, my optician will not furnish both on the same pair of glasses.

[modeng2000Participant @modeng2000]

Very interesting OMG, I'll have to ask about this on my next visit.

[Clive HartlandParticipant @clivehartland94829]

I have as I have aged, needed reading glasses and opted for the type where there is a lense glued to the bottom and I have no trouble using them. I also opted for the reactolite glasses and then went to work on the bees and as the Sun was out I could not see the bees as the glasses darkened so had to go back and get another pair just to work the Bees.

I work on things very close up like very small bearings that need regreasing( These are fitted to the ends of the footscrews on Tribrachs by some makers) The ball bearings are very small. Also I need to look at Glass surfaces for cleansing and to see dust specs. Machining I have no problem with measuring or seeing what I am doing.

[ChrisHParticipant @chrish]

I use varifocals, complete with reactolite built in and anti reflective coatings. Have had no problems at all except one which I will come to, and wearing them i find no bother at all, would not be without them. My wife has had a problem with hers, getting a double vision or halo effect over the top, but that might be due to the thickness of the lens for her.

The one problem I have had is with the reactolite. I not very often go welding, but when I do it is outside. Now my welding was never the best but I have found that using my usual glasses I really struggle as I cannot see what I am doing as the darkened reactolite due to bright outdoor light combined with the welding glass means all is very dark indeed. I have just got new glasses, plus a spare pair without the reactolite for when 'working'. I have yet to try welding with them, but am hopeful I will be able to see a bit more. Bit like Clive's comment seeing his bees I suppose!

I have 'rescued' a two year of pair of glasses using 'armour etch' to remove the crazed coating from plastic lenses.

1 never let your coated lenses in the bath!

2 never dry them with a towel!

3 when they go bad, don't use mechanical means to remove the coating.

My experience only you may have a disaster! – I'd only do this with a pair that was otherwise ready for the bin.

Neil

[Gone AwayParticipant @goneaway]

I'd be careful what you clean coated lenses with too. I'm pretty sure dish-detergent (washing up liquid) is bad over time also home made concoctions using isopropyl alcohol with or without dish-detergent (ask me how I know).

These days, I mostly just run them under the tap (warm water) and lightly swab them at the same time with a paper handkerchief. Then just pat off the excess water with a dry piece of the paper hankie. (I don't rub dry paper hankies on the lenses – bit too abrasive for that). Normally, that's all it takes.

Occasionally, if the lenses are really bad, I go the whole hog and, after washing as above to get the dust off, I clean them with proper lens-cleaner and a lens-cleaning cloth.

[Neil WyattModerator @neilwyatt]

Well I 'found' my reading glasses, and I'm using them now. Funnily enough I get a good view of the computer screen, and it's getting better as my eyes are forced to accomodate. I don't know if this experiment will give me a headache…

The left eye now sees the screen sharply, enough to be aware of the pixels as a 'texture' (I hate iphone screens as my short-range acuity without glasses means I see the 'white' as a dancing sea of coloured dots, I don't see this with any other type of screen I've encountered).

My right eye is still fuzzy looking at the screen, but sharp if I lean a third of the way towards it. so I've made a 'lazy-eye patch. I've also done a bit of crude refocusing (bending) as making the lens a couple of mm closer to my eye made quite a difference -enough that I can read and type with just the right eye.

The blooming keyboard is pin-sharp. Hopefully this will let me go to say left eye is fine, right eye needs -0.25 to -0.5 stronger.

[John McNamaraParticipant @johnmcnamara74883]

Hi Neil

My eyes do not match perfectly but the optician corrects each individually, Could it be the person making up your prescription made a mistake? I would go back for a retest. (They can also check the existing pair with a machine against the prescription used to make them up if not I would ask for a new pair FOC).

When I Ordered mine I got the lower middle section to start focussing at screen distance in my case about 600mm that is also about right for lathe work the lower section for closer reading means that if have to look down. The upper section is for distance.

I also always try to get the largest metal frame aviator style glasses for the best eye protection when I am not wearing safety glasses. The penalty being weight.

Regards
John

[Geoff TheasbyParticipant @geofftheasby]

Neil,

I have exactly the same problem, which makes reading uncomfortable, as a decent distance for my left eye is too far away for my right. I have also been diagnosed with a slight squint, which tends to create double vision, and means I am no longer confident about driving, as I am unsure of my position on the road. Fortunately Debs is a good driver.

Geoff

I use Meths to clean my glasses, applied using a paper towel.

Works well, and none of the smell from proprietary products.

Geoff – Nice one Lewis!

Are they plastic lenses? Coated?

Thanks for the spoiler (haven't seen the race here yet). Wasn't expecting a spoiler in this forum.

> Could it be the person making up your prescription made a mistake?

No, I think I've dramatically lost accommodation since getting the glasses, especially on teh right; the reading glasses were hardly used because of the other pair I had, and I think my 'range' had changed too much by the time I came to use them.

Can't believe I saw the day the Tour de France relegated a Briton winning the British GP to a footnote on the news!

Neil

[OuBallieParticipant @ouballie]

OMG,

Plastic lenses.

Spoiler.

I bow my head in shame

Did you really expect anyone else to win?

He was so fired up after that total brain out of gear cock-up on that last Qually lap!

Best of all is having Williams back on form, but lucky escape for two drivers though.

Where did they find Bottas?

Neil,

The West is anti-car from all the bull manure from a lot of people, the latest from dear Boris who wants to ban ALL Classic cars due to their 'polluting' the 'clean' inner-London air.

No doubt all the Chelsea tractors and other gas guzzlers will be exempt. There is a protest site up for signing http://www.classicandsportscar.com/news/general-classic-car-news/the-free-use-of-classic-cars-in-central-london

Geoff – Just back from an hour in the dentist's chair, & now sipping Rooibos.

That link keeps appearing at the top of the post, so inserted the text instead. Can you fix please Neil?
