Multifocal Contact Lenses - Any Experience?

[solwisesteve]

Rgp (rigid gas permeable) are small, hard lenses, usually annual replacement.
Dailies and monthlies are soft lenses.

arrr... right.

[solwisesteve]

Another 35mins wasted this am and two lenses in the bin.

I'm 90% close to chucking the whole lot :-(

I'm going to give Boots a bell and book another training session.

The problem is I touch my eye lashes or whatever and blink and then the lens is a mangled heap on the end of my finger. Tried two eyelids holding, one eyelid, one handed, two handed, look up, look straight, onto the whites, onto the pupil. After half an hour you start to loose patience and just start ramming the damn things into your eye :-(

[Kingstepper]

Hold eyelashes up with forefinger and lower lid with middle finger of other hand. Shouldn’t be possible to touch eyelashes with inserting finger. Even if you blink, if lids well held, lens should still go in.

Yes I tried that... though, tbh, I tried so many permutations that I've lost track now ;-)

I think I've lost patience so time to speak to Boots, have another try with them sat next to me. If I can do it two or three times with them then I'll give it another go at home. At the moment a bit despondent and god knows what my blood pressure is!

[Kingstepper]

Don’t wear them now but when I did think biggest problem at first was being too tentative.
Persevere, maybe bit more training (those ladies are nice!) you’ll get there.

Just takes a bit of practice. Millions of people do it every day, so you can as well.

I have had multifocal lenses for a while, they take a few days to get used to them (owing to their principle of working, very well described in this post). The result is not 100%, but I found it acceptable. I stopped wearing them when my nearsightedness worsened: when wearing glasses I had the option of looking underneath the glasses, but that doesn't work with lenses. I might try again when my vision has stabilised (hopefully in a few years). Until then, I only wear contacts when swimming/diving or in the sauna and have bought reading glasses to be able to read while wearing contacts.

95% of the time I wear my multifocal spectacles, as that works best for me. Oh the fun of coming of age...

[Kingstepper]

Swimming with contacts is certainly not advised due to risk of infection.

Thanks, I never knew.

I actually discussed with my optometrist that I swim in them and never got any feedback (swimming was actually one of the reasons why I originally started to wear contacts 20+ years ago). A quick google explains why it isn't recmmended and that makes perfect sense.

[PhilipK]

Swimming with contacts is certainly not advised due to risk of infection.

Is that true even with goggles? (I've just started taking swimming lessons, and I have been wearing goggles to keep water out of my eyes, but I'm not quite at the point of buying prescription goggles!)

Also, FWIW, I'm paying £40 a month for daily disposable multifocals on the Specsavers Lensmail scheme.

[solwisesteve]

My optician also said no swimming because of the chlorine etc... chemicals. When I asked about a salt water pool (I have to play the smart alec), i.e. like the saline solution you wash the lenses with anyway, he didn't have an answer ;-)

[WarrenVrs]

Swimming is ok, but only if you remove and dispose straight after. Obviously only really works with dailies.

Goggles with a decent seal should be fine, but if chuck the contacts after if pool water did get in.

I wouldn't wear them on flights either.

For practice, sit down and practice opening the lids and touching the white of the eye. Only the white! Don't go near the cornea. Goes without saying to wash your hands beforehand.

Whatever water you're swimming in can harbour huge numbers of bacteria and other micro-organisms, which can attach themselves to your lenses and lead to infections. Additionally, the lenses are highly water-absorbent and so they can swell and change shape, which can irritate the eyes.

The advice I've always had is to avoid swimming or showering in lenses, but if for some reason you must, then you should wear waterproof goggles and throw the lenses away immediately after you're done.

[Itsguy]

I use the CooperVision 1 day multifocals and find them very good. Note though that it can take a few days to get used to them, you won’t necessarily get the best results straight away so give it time. Your brain needs to work out how to process it, and you may also have to get used to what distances work best for reading. I wouldn’t say they’re as good as proper progressive glasses, particularly in low light, and there’s more of a trade off between near and far focus than with progressive glasses. But for most everyday purposes they’re great, you can just see and soon forget you’re using anything. I use them on the motorcycle, glasses under a helmet doesn’t feel right for me. They’re also handy for watching 3D movies at the IMAX without having to wear two sets of glasses.

Sometimes I get caught out by a restaurant menu by candlelight, that some idiot decided to print in tiny, elaborate italic writing on dark grey paper, and I’d still prefer glasses for working at a computer or watching a ballet from the cheap seats, but in the day and for socialising they’re ideal.

For getting them in, make sure you have a good magnifying mirror, you can get small ones that just stick on your normal mirror with a suction cup, simpler than bulky shaving mirrors and you can take them on holdiday in your wash bag. Holding the eye lashes with the other hand so you can’t blink works for me. A dry-ish finger helps, and make sure the lens hasn’t sucked onto the finger tip. Be sure to wash hands first to avoid eye infections. Good luck!

[PhilipK]

Thanks for the various comments about swimming - something I hadn't really considered.

I've no desire to get an eye infection - been there, done that - so I think I'll need to dispose of my lenses straight after swimming lessons (even though I'm still in the salt-water "kiddies" pool) and wear my glasses for the rest of the evening.

[SimonH]

I really struggled with mine at first, but had another training session and the lady really helped me immensely. The main mistake I was making was to apply to much pressure, in essence you just need the faintest of touches of the lens to the eye for it to attracted to the eyeball if that makes sense. Also, I use left hand to hold upper lashes out of the way, middle finger of right for the lower, and apply the lens with the index finger. The other thing is not to blink too quickly once inserted which I struggle with so I actually lower the eyelid with my finger.

I think I did both mistakes.... press too hard on the eye and also blink too soon after removing finger with the consequence I found it stuck to my eye lid :-(

9:15 tomorrow at Boots.

bwt, assuming I get used to them etc...., I was looking at the Air Optix Aqua lenses which seem to have a lot of advantages over dailies i.e. supposed to be easier to fit and you can even occasionally sleep in them, oh.... and they work out a lot cheaper!

I'm just off for an eye test and trial of the MF torics

[solwisesteve]

Hold it!! There are tools for this job...

That's one but there are loads of different makes.

You will never learn to apply them correctly if you use these tools. Completely useless once you mastered the technology.

Personally, I wouldn't sleep in them. Or recommend a patient sleeps in them.

Right.... so a 45 min training session at Boots Friday am and now my 3rd day fitting on my own. A bit fiddly this am but probably because I was rushing with getting ready for work. I found that putting the lens literally right on the tip of my finger helped because less chance of touching my eye lids and hence blinking. Also pulling the top lid up with hand reaching from above. Then DON'T BLINK after putting the lens on the eye.... carefully swivel eye around and then gently release the eye lids. Thanks for the pointers with this.

Anyway they're in now... tbh I'd really like reading to be a little better but another visit to Boots this Friday so I'll mention it then. Also the quote for the price was total rubbish. So the quote says £17.50 per month 30 pairs. Now I thought that meant 30 pairs a month... NOPE.... that means 30 pairs every three months! Anyway I've decided, if I stick with it, to go for monthlies which are a heck of a lot cheaper and look better lenses anyway.

So issues....

I'd like the reading end of the vision to be better. But that's tuning the strength.
Also long distance flicks between good and bad. I can make it good by blinking hard. Then far vision does a big improvement. But over the course of a few mins it deteriorates again. So I'm tending to walk around like a dutchman saying hi all the time!

Anyway that's my findings so far.

Good to hear perseverance is paying off!

I can't get my head around the pricing / wearing schedule they've given you though. Assuming they're dailies, are they saying you should wear each pair for three days, or am I missing something?

Still waiting for "the call" from Vision Express for mine...

[vulcangascompany]

Interesting discussion i’ll need these soon but over the last few years have been put off Boots. They are eye wateringly expensive and their service is going downhill fast. The opticians never used to be pushy but they obviously now have sales targets and want you to take the most expensive option - check out other options before signing up to one of their ‘plans’ it will be probably cheaper than Boots!

They don't seem to have considered the concept that people might actually want to wear dailies every day! They think that dailies will only be worn occasionally for going out, social events, etc... So you might pop lenses in for a night out but not every day for work. Hence the 30 pairs to last you a month. I gather people use monthlies for everyday wear.

Yes.... I'm going to continue with Boots whilst on the free trial and taking advantage of the various lens options (powers) but after that I'll probably just buy monthlies from someone like visiondirect. tbh Boots have been very good service wise.... I'm going to ask on Friday (next appointment) what the options/costs are for monthly lenses.

Funny - I always thought that dailies were aimed at those who wear lenses all day every day, and I always liked the idea of putting in a fresh, new, sterile pair every day, as well as the convenience of them. Seems I'm in the minority though.

Like you, once I've settled on the right parameters, I guess I'll be shopping around online for the best deal.

[solwisesteve]

Another visit to Boots. Now, today, just started with the 'monthlies'. Boots reckoned the daily lens was slipping down a touch and that's why it was better just after a hard blink. So the monthlies are a more acceptable £19pm (and that's for a pair). On a trial for two weeks with them. After a break of 4 days waiting for them to arrive I was out of practice fitting them so 20 mins this morning putting them in :-(

Anyway first impressions are they're better for reading... okay for distance. Distance is still better without them and, tbh, reading isn't as good as with reading glasses but, saying that, I am typing away on the PC okay with the lenses which I wouldn't be able to do without eye correction. I'll give it a few more days before drawing any conclusions.

I looked on the various web sites and the price from Boots is en-pare (is that how you spell it) with the online sellers.

Good grief, I've just reread what I typed above! How many 'thems' are there in those few sentences!

[DMC102]

Sounds like progress!

Still waiting for mine to come in to Vision Express. Seems that the torics are made to order and take about a month...

I'm surprised at the 'made to order'.. Vision Direct have them as an off the shelf purchase and I think they ARE Vision Express. I'll be interested on how you find them... I'm thinking of giving them a try. The price is much the same (well it is from Vision Direct) as standard multi-focals so I don't know why they haven't been suggested by Boots. I think I'll ask them in two weeks at the next checkup.

Vision Direct have them available to order, yes, but - at least for my parameters - when you get to the checkout they state estimated delivery in about a month.

I'm pretty sure there's no connection between Vision Express and Vision Direct.

[solwisesteve]

I'm pretty sure there's no connection between Vision Express and Vision Direct.

tbh I've been on so many online lens sellers web sites you're probably correct... I'm sure one of the online sellers said something about collect from vision express though it might well NOT be vision direct - looking at online sellers, reviews, forums, tech sites, it's starting to blow my mind!

Lol yes it's a bit of a minefield.

One thing I've learned from years of using Vision Direct is never to go to the site direct, but instead by searching for your lenses on Google and clicking their Shopping ad. I almost always get a lower price that way.

[de30m]

Well as I’m responsible for two factories making around 1.4million lenses a day I can add something to this

On the specific designs of Multifocals

We make two different multifocal types the concentric power rings as so well described above by DavidL, and is the most common MF design, and also a balanced progressive (BP) design unique to us that is effectively a varifocal with a smoothed power profile from the centre zone out to the periphery with up to about a 2 add and this was developed by Essilor through their then contact lens subsidiary from their glasses lens technology, in fact as a young production engineer I worked on developing the metrology needed to measure this on a contact lens and programming the six axis lathes used to make the optical parts that form the moulds for these and this design is now part of our product portfolio after a number of acquisitions over the past 10 years

We are currently developing a combo version of these two multi-focal designs that uses the concentric ring design for high adds and the balanced progressive design for lower and mid adds as a one day, this is because for lower add powers the balanced progressive design is easier to live with, but less successful at high adds

We make BP MF 1day lenses (Proclear and MyDay), standard MF (Clariti and the hydrogel MF own brands from most major opticians which we make too)

A multifocal toric is available as described above, only from us but this is a made to order lens we can make in any prescription and in both hydrogel and silicon hydrogel technologies, but at a cost as it is very rare fitment but not planned in single use format, our 1day process is designed for large volumes and is how we achieve the economies of scale needed to enable us to make both daily and monthly lenses across so many different products


Own brand lenses from almost all the major opticians are made by us such as vision express, specsavers, boots and that’s just the big three UK brands, we make over 4000 different branded lenses globally


Oh and just to be 100% clear, I can’t get them for anyone as all contacts lenses are a prescription medical device so only available via a qualified optician ( slightly different rules apply around the world)

Vision direct is part of Essilor

Vision express is part of Grandvision

They are very much competitors but in slightly different retail spaces, first one being almost entirely online the latter largely a physical retailer with added online availability

Well, thank you very much for your input. Despite our leaders’ opinion regarding experts, it’s a rare pleasure to learn something directly from the horse’s mouth, if you’ll forgive the expression.

A question if I may. Being an aging ( thus with a dose of astigmatism) shortsighted (around -5 for each) bloke, is there one lens technology that will (or is) a valid equivalent to spectacles, for driving, working on screen and mobile phone please?

[Neilw3030]

Have been trying multi focal dailies on and off for awhile now. First trial was with Boots, but they refused to give me anymore help getting the prescription right after my third attempt. I would have to pay.
Only thing is the ones great for reading left me unable to drive, tweeked slightly and improved driving but not reading abilities.
To try and understand, the power is for close work and the add is for distance? Is that right?
Dailies online are costing me over £50 for 30 pairs so I think monthly lens could be a better option.

Thanks for that and no problem I’ve been called way worse!!

I’ll qualify my answer by saying I only make them, the prescription and fitting of them is something I only understand from being part of the industry and have no expertise in that field.

Lenses are always more of a compromise for near and distance correction as a pair of glasses however I would say at your prescription level you should be well served with normal aspheric lenses if you don’t need a multifocal for the close up work but if you need a near addition it will depend on how much that is if you need a BP design or concentric ring design and either way then depends on your eye if you need a high water content or even a silicon lens

There are a lot of questions your optician would ask to steer you to able to answer these questions

There are good reasons for each modality and material

I am hugely biased as I developed some of these lenses and that’s before I get to the fact i work for the company that makes the biggest variety of lenses on the market
and I run two of the factories making some of the best of them

Do you wear lenses now and do have any challenges with them, I can give some guidance maybe from that

[Saint-Just]

I only wear lenses on sunny days with my sunglasses, and away from the computer, as my varifocals are more suited for mid and close distance work.
I read without my glasses without any problem.
The fact that my CL are not varifocal means that I tend to restrict their use to outdoors activities. They are 1 day Acuvue Moist.
I am happy with the service we get from Vision Express but as they are not exactly independent either I am grateful for your opinion.
I have worn CL 40 years ago, stopped after a damaged cornea and have worn them again whenever needed the last 20 years.

As a single vision lens 1 day acuvue is a good lens and for a long time the industry leader, however that is based on silicon lens technology that is now over 10 years old

The benchmark lens for most of the last 10 years in clinical studies and what we used to develop our newest lenses especially MyDay

MyDay uses the now newest and best silicon 1 day technology and is the fastest growing lens in the market

this is available through most opticians and is now the standard used for comparison in clinical and the #1 and #2 lens for quality and performance in the toughest single use lens market, Japan.
We are 1st and 2nd because we sell MyDay under both it’s own name and as a brand for Menicon

We don’t yet do a MF MyDay though as we are still focusing on single vision and torics and we are fully committed on capacity for the next 2 years on those but it is on the way as new lines are in build now

I know that reads like an advert but on the basis that we cannot keep up with customers demand now, I really don’t need to try to upsell the product.

Yes I also helped develop the process that makes this and it is our newest, measurably most capable and highest performance process and I am now responsible for the manufacture of half the global supply of this product

[burnside]

I’m reading this thread with some interest.

I’ve had glasses for years and did try contact lenses a very long time ago, but one got stuck to my eye ball and I ended up looking like the Terminator for a bit and the optician had to remove the offending article.

I struggled to get them in and screwed my eyes up a lot so didn’t get on with them so went back to glasses.

Ouch, enough to put anyone off

likely you were fitted with the wrong base curve or you needed a higher water content lens to improve mobility on the eye and the lens dried up and stuck to your eye

Early silicon lenses were very stiff and RGPs as per their name are rigid and both can force your cornea into the shape of the lens, causing fatigue if the base curve radius is too low

Conversely high base curve lenses can curl up in the eye as the lens edge doesn’t maintain good edge contact with the eye and your eye lid rolls them over

High water content materials and smart silicon lenses now have some ability to form to your eye shape and eye fatigue is much reduced and comfort levels far higher and much easier to fit compared to RGPs and high modulus silicons

[burnside]

It was a very long time ago but i'd put it more down to user error than the product, but possibly technological and material advancements would mitigate a clumsy idiots approach these days. Maybe!

As an alternative to multi focal lens, how does mono vision lenses compare?
Was chatting with one of my customers a few weeks ago and he said he had gone mono vision and found it much better vision wise, and cheaper to boot.

It works but not for everyone and not everywhere and depends on the gap between your near and distant prescription

I’d not want to be driving and have a car pull out on my non dominant side and the resultant distortion to vision from my reading eye having to respond

Most of the time ok but when you need stereo vision it could be a compromise if the corrections are a long way apart, but it’s amazing what your brain can work out from what your eyes are seeing when you need to

It was a very long time ago but i'd put it more down to user error than the product, but possibly technological and material advancements would mitigate a clumsy idiots approach these days. Maybe!

Still have to get over the horror show last time from last time, might struggle to hold your eye open with that memory!

The comfort and range of lenses now means anyone can wear lenses pretty much

I do this and have no problems did try varifocals and can’t drive with them, the option I have tried is good lenses for distance, sport and then reading glasses and this works well too. But do wear varifocal glasses and they are good and my most common choice day to day.

I did struggle to put them and it takes time a perseverance, now quite easy to do.
