Firstly I have to state that these contact lenses are something I totally rely on every single day. I cannot wear glasses - they make me sick (no I won't get used to them, tried that few times) and I can't go without anything as I have quite strong dioptries (-2.5).
These contact lenses are monthly - Continuous Wear ones. That means they are made of soft material (AerGel) that allows oxygen through freely. For someone like me they are the most convenient option - you put them in and leave for a month, then you take them out and dispose of them. You can swim, shower, sleep with them - you can do pretty much anything you need as if your eyes were healthy. However, they are also least comfortable ones - your eyes must be in otherwise perfect health - no abrasions, scratches, etc. as the cause irritation quite easily. Also, it is wise to give your eyes a break sometimes - I normally take them out for night few times a month, but have gone through few months without a break without heavy damage.
I must say they are a bit irritating during pregnancy (sometimes you feel like you have an eyelash in your eyes, nothing worse than that), but I suppose that is very individual feeling.
The only real inconvenience comes when you are starting with them - as they cause most irritation of all types, you need to be checked by optician a day after you put them in for the first time, and then again after a week. After that you don't need to come back until your normal check up. Ordering online is rather cost effective option - I order a box of 3 pairs for £21, which is comparable to cheapest "take-out" monthly lenses from high street opticians.
These contacts make my life so much easier, I don't know what I would do without them. Highly recommended if your eyes are not sensitive.
For me, and I believe many people, contact lenses are a matter of self-esteem rather then simply preference or anything else. I believe (and have been told) that I look so much better in lenses then I do glasses. However, I don't like faffing around with them every day taking them out, cleaning, putting them in etc. So, when I found out that I could wear continuous wear lenses I jumped at the chance. The particular kind of continuous wear lenses I use are these; Bausch and Lomb purevision.
What Are They?
Bausch and Lomb do many different kinds of lenses, these ones in particular are designed to be used either as a 30 day monthly disposable or as a 30 day continuous wear lenses. Bausch and Lomb claim that these are made with a "unique AerGel material"; they say that this means that more oxygen is allowed through to your eyes meaning that you can see "rich contrast and detail" while ensuring that you remain comfortable. Apparently this AerGel material also helps to repel debris and provide long term moisture to your lens.
They are available on prescription between -12 and +6, a base curve of 8.3 or 8.6 and a diameter of 14.0.
Technically, since I have a mild astigmatism, I should wear lenses designed especially for that but they don't do those in continuous wear and since I cope with these ok my optician is happy for me to keep using them. This does however mean that my vision isn't quite as sharp and clear as it could be with some lenses.
I haven't found this to be a problem at all with these lenses though. I'm short-sighted and when wearing these, even objects in the distance are very sharp. I have experienced no blurring, difficulty making out images or reading road signs in the distance. I've also experienced no halo like effect around lights that you get with glasses and some lenses.
I take out the lenses weekly to give them a quick clean and besides a little protein build up I haven't no debris or other dirt on the lens but then I never experienced this with other lenses either so it's hard to say if this is due to their AerGel material as they claim or if they would have been clean anyway.
Comfort wise I do find that my eyes can get a little dryer with these then with other lenses I have tried, this may be better if you use them as a monthly disposable rather then continuous wear but I combat this by using rewetting drops and this solves the problem completely for me. Besides this these lenses are very comfortable and they stay in place perfectly without slipping round my eye.
I'm going to give them 5 out of 5 and highly recommend them. However, as with all lenses consult your optician before changing brands.
Price And Availability
I buy my lenses from Lensway, they retail for £39.89 (for a box of six) at usual price but are almost always on offer, Currently you can buy them for £19 per box, on top of this there is 5% handling and insurance and postage charges.
They are however available from almost all opticians but prices vary so it's worth shopping around.
I have been wearing colored contacts for three years. My eyes suddenly got so irritated to them. The doctor said that I am experiencing corneal swelling. I don't really understand it but the doctor informed me that I was starving my eyes with proper nourishment, I was over-wearing my contacts!
Well, I admit that I have slept with my contacts frequently. But after weeks of using glasses and having my eyes recuperate from the injury. The doctor told me to use PureVision. I got a little sad because I use to wear colored contacts.
I didn't have problem the first day I have used it. It didn't dry up too much. I no longer need to put eye drops frequently. I got less irritation compared before. I still sleep with my contacts occasionally. But it was okay with my doctor. He said that I can wear it for longer hours since it was designed to be used that way.
I also notice when I examine my contacts there are less dirt that accumulates. I don't know how it happens or if the contacts repels dirt but I can say this is an extremely good quality contacts.
This is the second year of wearing Purevision, and I will continuously wear it coz' I value the health of my eyes.
I had been wearing glasses for years, until one day my optician says "have you ever tried contacts". So I thought I would give them ago. They are a soft lense and allow a high percentage of oxygen through to the eye. On first putting these in I wont pretend they where comfortable straight off. As with all contacts, putting something into your eye is not normal. But this is something you soon get used to. I wear these lenses on a monthly basis. I put them in at the start of a month and then eat, sleep and..... After wearing them continuously for this length of time they still feel comfortable. Even after a full nights sleep, I awake and my eyes feel fine. My left eye has a stigmatism, but these lenses seemed ok with that too. I have worn these on numerous occasions whilst working in the heat and dust of Iraq and again they worked well, with no problem. I know a few people who have tried these lenses and they have not got on with them. As with most contact lenses it is a matter of trial and error, but all in all these are very comfortable.
I had to buy both Toric lenses and the Aspheric lenses because I only have astigmatism in my left eye so I'll do a review of both. I found that actually, the Aspheric lens compared pretty well against the Spec Savers version I was using previously and I think that the quality of the lens seemed to be slightly better (it was a bit thicker in my opinion). The only issue I really had was that towards the end of the month, a build up of dust and dirt did appear (even though I cleaned the lenses quite carefully) which made the contact lenses quite uncomfortable for the last few days.
However, for most of the month, the Bausch and Lomb ones were really quite comfortable so, if ordered in bulk, it can work out to be a lot cheaper than getting it from your opticians direct. Unlike the Toric ones, I think that the investment is definitely worth it. Also, I think that the issue of dust and dirt might be due to the solution I was using (still the Spec Savers ones, not Bausch and Lomb) so perhaps if I used the recommended one then that problem would be solved.
I had been wearing monthly disposable contact lenses for about five years when my optician suggested I try these new ones. I took them out once a week, overnight, as recommended, just to give my eyes the chance to breathe, but otherwise left them in 24/7. I had no problems at all and absolutely loved the freedom they gave me: no more fiddling around on a nightly basis with solution and sticking my fingers into my eyes. These lenses didn't dry my eyes out either, whereas the old ones did.
Three years after beginning to wear them, I developed some problems with my right eye. I went to the eye infirmary and was told I had a viral infection, and would be unable to wear my lenses for up to six months. They also said that they advise against this kind of lenses because of the problems they can cause, and they had seen some serious problems because of them. However, it was my decision whether or not to start wearing them again once the six months were up.
Because I love them so much, I DID start wearing them again, but I now leave them out one day a week just to give my eyes the chance to breathe. Six months on I have no further problems and I don't regret my decision. I definitely recommend these lenses, they are genuinely, I believe, life-changing; but you do have to be very careful.
I get mine from Specsavers: they are £15 per month via Direct Debit at time of writing, and include free check-ups and a free eye test once every two years.
These contact lens are the monthly wear ones. I have been using these since they first came onto the market several years ago. I have strong prescription -7.5 in both eyes. I work shifts so had found it really difficult to use conventional contact lens as I never seemed to get the hang of them especially with night shifts. I tried these and the first time in my adult life I woke up and could see things which let me tell you was a big wow. I have generally put these through their paces especially with working long nights shifts during which the best of eyes get tired an dry but i never had a problem. During the time i have used these i have also had knee surgery and with conventional lens you couldn't wear them but with these lens I was able to keep them in and hence felt less disoriented when i came round from surgery. I would say to get them from a good optician as then you can be check to see if they suit you.
I've recently started to use these lenses as an alternative to laser corrective surgery - my prescription is low at -1.25 in each eye and I would be a good candidate for surface abrasion laser surgery which is virtually risk free, but I just wanted to see if I could get the benefits of 20/20 vision without the need to burn the front of my eyeballs away.I usually use a mixture of glasses and daily disposables but with sports this is becoming a pain. I've used these lenses now for a week and whilst there is some minor irritation for a few minutes in the morning when I wake up they have otherwise proved extremely comfortable. Definitely a good alternative to any other solution based on the evidence thus far
I read the only other review on these contact lenses and fall to the conclusion that he is right in many aspects.
my prescription is -4.50 in my right eye.
I feel that the contact lenses are fantastic and its a wonderful feeling that when you wake up you can see...but thats not strictly true as depending on how bad you eye sight is...you may wake up having blurry sight for a few second like i did...every night for the last 180 nights, yes the blurriness went but always felt worried about washing the lense out of my eye.
I would buy them again though as they are the best for my eyes, i have not tried any other lenses.
in regards to keeping them in for longer i have also done this, because my eyes are bad due to an eye accident while in primary school.
once i was also very naughty and wore my monthly lenses for three months, i never took them out even though the opticians would never recommend them to me again if they knew...they would probably treat me like a little kid. my eye has been checked again and my eye sight has worsened a little but not too much. i would not do it again though.... also i would not recommend doing as i did by wearing the lenses longger than a month.
i buy my lenses from vision express in bexleyheath every three months. in effect it costs me £6.66 per lense. if you was to google bausche and lomb thei rwebsite is very useful on advice and stockists.
the only downside is that you can't get them in a colour option, they are great and would recommend evey time.
i too also considered surgery but when i went for the assessment they said i was not eligible....which was a shame...i shall pursue that later on.
via vision express you need to have a check done every six months which costs £35.00. this is my downside.
Purevision are a disposable soft contact lens that you can wear continuously for 30 days. This review is aimed at those who already wear contact lenses, as I doubt that anyone would use continuous wear lenses as their very first lenses.
I have a fairly strong prescription (-7.50). I have been using Purvision continuous wear lenses for nearly 4 years now. I've been wearing contact lenses generally for around 17 years, gradually moving from pemanent soft lenses, to disposable monthlies, to the continuous wear. I find them absolutely fabulous.
I found that with non-disposable lenses my eyes were not getting enough oxygen and blood vessels started growing across my cornea. I also had higher calcium and protein deposits on my lenses than average. So I made the switch to monthly disposables, which sorted the problem out. When I decided to go on a 5 month backpacking trip through the middle east, I decided to look into continuous wear lenses for several reasons:
1. My vision is really bad, and I didn't fancy waking up in a hostel in the middle of the night and having to fumble for my glasses.
2. I didn't want to lug around 6 months' supply of cleaning gear, and didn't want to rely on being able to find it on the road.
3. I was worried about hygeine - I was not always going to have ready access to clean bathrooms to wash hands etc.
I therefore trialled a pair of Purevision lenses. According to my optometrist I am the best candidate she has ever seen for these lenses, so I am very lucky. If you have a tendency to dry eyes, you may not be suitable, or you may need to spend a small fortune on regular eye drops.
The lenses are specially developed to allow more oxygen to access the eye than standard soft contact lenses. Irrespective of the extended wear function, these lenses are actually the best for me because of this oxygen access. The continual wear is really just a bonus, but boy what a bonus!
According to their website these have:
" Special Performa surface treatment repels protein build-up, providing the most comfortable experience all through the day and night . PureVision contact lenses provide 4 to 5 times more oxygen to your cornea that conventional csoft lenses, greatly increasing comfort and freshness . Unique AerGel technology balances oxygen and water to provide all day/all night comfort"
I wear the lenses continually. I am supposed to take them out once a week for a few waking hours, but I have to confess I tend to forget. I try to make up for this by having periods of a week or two every couple of months where I do not wear them at all. I do take them out whenever I'm unwell at all, or if my eyes are feeling tired, which virtually never happens. What I do do fairly regularly is rub them with an all in one solution, which I find helps a lot, especially towards the end of the month.
I find these lenses incredibly comfortable. They are very thin, which means it can be difficult knowing whether they're inside out or not when putting them in. I think that if anything they're more comfortable than regular lenses, but I find all lenses comfortable, and unless I'm tired I can't feel them at all.
When first wearing Purevision you need to check in with your optician regularly so they can make sure that your eyes are suitable. When I first started wearing them, my eyes would be dry in the morning. The lens can stick to your cornea, but an eye drop or two sorts things out. As time goes by your eyes get used to the lenses and mine stopped drying out after a few weeks.
The joy of having perfect vision all the time is absolutely amazing. As someone who has had bad eyesight since early childhood, waking up and being able to see the time is wonderful.
I have had no problems with the lenses at all. One thing I do have to be careful about is knowing when you have an infection starting - I have had an infection a couple of times previously with other lenses, and you don't realise while you have the lens in. It is only when you remove the lens that you can feel the discomfort in your eye - the lens acts as a buffer. So, if you're not taking your lenses out, presumably there is a risk that you will not realise you have an infection developing. I am slightly paranoid about this, and will whip the lenses out if I have any concerns whatsoever, and more than once I've gone to the optometrist worried there's something wrong when everything has been fine. You just can't be too careful with your eyesight.
I had been considering laser surgery, but with the risks involved, I simply can't justify it. The lenses will cost more over a lifetime than the surgery would, but otherwise the benefits are virtually the same.
These are one of only 2 or 3 brands for continuous wear lenses. Ciba Vision do them, and I've noticed you can now get some own brand versions. I find that the Purevision are normally the cheapest anyway as I buy online, and being Baush & Lomb, it's a reputable brand. I have not tried the other brands, and don't know anything about them. I have simply stuck with my optometrist's recommendation.
The lenses can be expensive, although they're cheaper than dailies. Frankly I would pay a lot more for them, so I think they're excellent value for money.
Over the counter they can cost up to £30 a pair. It's far cheaper to buy over the internet - sites such as OKvision and Post Optics used to have the best prices, at around £12-15 a pair (for 6 months' supply), so between £70-85 for the full 6 months.
12 months' supplies are usually cheaper again, but my prescription has not yet stabilised so I don't buy that much at once. I've not yet made the leap myself, but buying internationally can be even cheaper.
However, Tesco.com have started selling contact lenses and Purevision are an amazing £8.74 a pair, which is just £26.22 for three months' supply, which is by far the cheapest I've ever seen them, plus you get the bonus of clubcard points etc.
Of course, whilst the lenses may not be the cheapest lenses around, you save on cleaning fluids. I just keep a small travel sized bottle of an all in one cleaner on me when I travel, and a big bottle at home, and that's all you need.
Now, a little secret - I cannot recommend doing this, but I have also been known to cheat (unintentionally) and wear them longer than 30 days. I am always forgetting when I started a new pair, and I'm sure I've gone over 5 weeks before, with no problems. I wouldn't recommend it and I'm sure the doctors and opthamologists out there are horrified, but nothing bad has happened to me (touch wood....).
I will never, ever go back to the other lenses. These lenses are way ahead of the others in so many ways - they are better for your eyes, because they allow more oxygen in, you can wear them 24 hours, you save on cleaning fluids, they are more hygenic because you're not handling them all the time, and you don't have to carry around lots of pairs the way you would with dailies.
Whilst medically they are not for everyone, I thoroughly recommend giving them a go.
Breakthrough technology, great convenience and supreme comfort have made PureVision contact lenses the preferred choice the world over. PureVision contact lenses are simply no-care lenses that can be worn even while you sleep. There's hardly a need for cleaning and maintenance.
