Product Info

Biofinity are a silicone hydrogel continuous wear contact lens, manufactured by CooperVision and made using their patented Aquaform technology, which creates a hydrophilic silicone hydrogel lens that allows greater levels of oxygen to flow freely through the lens to the eye helping them stay moist and comfortable al day long.

Higher oxygen supply lenses are known to create whiter healthier looking eyes for most contact lens wearers.

Biofinity contact lenses are designed to be worn all day and up to 29 nights in a row, they posses and maintain a high level of water to ensure the lens remains soft and flexible, delivering real comfort through the day and night.

Combining this perfect balance of water and exceptionally high levels of oxygen, Biofinity fells almost as natural as wearing no lenses at all. Biofinity is a naturally comfortable lens lens with no additives, coatings, wetting agents or surface treatments so nothing comes between you a more comfortable lens-wearing experience.

Biofinity also contains Aspheric optics which enhances vision even in low lighting conditions and helps with peripheral vision.

Good To Know

Why Should I wear Continuous Wear Contact Lenses?

Like may continuous wear contact lenses Biofinity are designed for all day comfort, all day every day, so you can put them in at the beginning of the month and continue wearing them comfortably for 30 days and 29 nights, knowing that your eyes are getting a healthy amount of oxygen not just throughout the day but also whilst you sleep at night.

Continuous wear contact lenses have been designed to be slept in, so if you like to take long naps party all night or work irregular hours, then this is the lens type for you. They are ideal for those people who have poor vision but want or need to wake up seeing the world clearly without searching for their glasses or inserting contact lenses.

How long Can I wear Biofinity Contact Lenses?

Biofinity are a silicone hydrogel continuous wear contact lens designed to be worn for up to 30 days. Although many people wear them daily or weekly they are safe and have been approved to be worn for up to 30 days and 29 nights consecutively, this is so that your eyes are given 1 night free of contact lenses before inserting a fresh pair for the following month.

Biofinity are one of the few contact lenses that you can safely sleep in.

Are Continuous Wear Contact Lenses Safe?

Continuous wear contact lenses are designed to be worn up to 30 days and although safe and healthy for your eyes they can increase the risk of infection, corneal neovascularisation (growth of new blood vessels into the cornea to increase oxygen supply), inflammation and irritation.
There are ways you can reduce the risks of complications due to continuous wear contact lenses

  • If you don't need to wear your lenses overnight every night remove them, clean them and soak them -give your eyes a break
  • Don't wear your lenses whilst swimming, in the hot tub etc - this is especially important with extended wear lenses
  • Remove your lenses and give your eyes a night off at least one a month
  • Follow your Optometrist advice
  • Attend regular contact lens check ups

Great lenses for all day use

I've been wearing contact lenses for around 18 years and prefer them to my glasses. These lenses ensure that enough oxygen gets to my eyes when I wear them for a long time, they're comfortable and my optician has noticed that my eyes are healthier since I moved to use them. Great price and delivery.

Consistently Good

I've been wearing these continuous wear lenses for about ten years now without ever a complaint, if anything they've got better in quality!

Comfortable for extended use.

Iv used these lenses for many years and will continue to do so. I like the extended wear as it fits in with working long shifts where the daily/monthlys start to fail. I find the lenses quite thick compared to others but I very rarely get any tears and knicks as a result.

Best ever

These are perfect. I can't feel them at all, easy to take care of, just amazing! Sometimes I do need to use eye drops, especially in the morning, but not every day. Unless I'm wearing them for too long, i.e. if I forget that it's been a month already. I mean I do take them out overnight every 2-3 days to let my eyes rest, but I sometimes forget that the pair is a months old already. They do get a bit uncomfortable then, but as I said, it's me, these lenses are fantastic!!! I've been using them for almost a year, and I'm not going back to anything else. And three weeks ago I had my eyes checked out, they are perfect, so no damage from continuous wear lenses, as many people fear! 10000% recommended!!!

Definately worth trying...

Having read all the reviews, I decided to try these and I must admit after wearing them continually for a couple of days I thought I had made a big mistake as my eyes felt dry particulary in the evening, however I persevered and afterwards I was fine with them and during the day I dont feel a thing and sometimes forget I am wearing them, I am in front of a laptop every day and they never dry out, I must admit I do take them out most of the time before I go to sleep but I know I can keep them in if I need to. I have just bought my second box and so definately worth trying.

Absolutely amazing!

These really are a wonder product! They take a couple of days to get used to, but I've been wearing them for 6 months now and they're so comfortable I forget I'm wearing them. Its like having perfect vision again :) I would strongly recommend these to anyone

If you're looking at these, chances are you're wearing daily disposables or monthly lenses and thinking these are too good to be true. I thought the same but took the plunge. Best decision I ever made. They are truly life-changing. I'm 6 months in to a round-the-world trip and I have barely had any problems. I take them out a few nights a month, about 50 hours or so total, just to give my eyes a rest, but otherwise you can't even feel them. I'll never forget when I woke up the first day and could see perfectly. These are the solution for anyone who can't afford eye-surgery or is too scared to do it.

First and only contacts.

I love these lenses. They really are very comfortable. I've had no problems at all. I expected to wake up with horribly crusty eyes or something in the morning, but I don't. I wake up bright eyed, and ready to see the world. The worst I get with them, is after about 8 hours on the computer (I'm a student, so I spend a lot of time writing essays) I find myself rubbing my eyes a little. I've only had them fall out once, and that was right at the end of the month, so I was meant to change them anyway. All I had to do was add a drop of multisolution and pop it back in again. No uncomfortable itching after or anything. I would recommend these for anyone.

Important - not for continuous 30 day use

These lenses are great - it takes a few days to get used to them, so have some drops handy. But it gets better quickly, and sleeping in them is not a problem. HOWEVER - they are NOT intended to be worn for 30 days continuously! They are recommended to be worn for 7 days and 6 nights in a single stretch, then your eyes need a rest and your lenses need a clean. I've seen people state in reviews that they have worn them 30 days straight - this is dangerous. Check the manufactures booklet:

Great Value Continuous Wear Lenses

I have worn more costly continuous wear lenses before and these cheaper lenses are of the same comfort. I told my sister in-law about these lenses and she tried them last month and re-ordered this month. They are a tad larger than previous lenses ive tried however they are just as comfortable. Will be ordering again.

the best I had so far

i had used different brands and types before, for me these ones are much better then daily ones which used to make my eyes dry long before end of the day.. i sleep with them as well without problems like with other types of contact lenses..still not perfect as sometimes they dont last whole month but overall the best i had so far

The Best!

These are lovely!
I must have tried most brands by now and although I am not easily pleased, I have to give these 10 out of 10.
I have very dry eyes, work in a warm and humid office and have my pc on all day.
These are the ONLY contact lenses I have tried which stand the test of time!
I have tried the rest, but am returning to the best..

I have been wearing lenses for over 13 years, and have used Biofinity continuous wear for about 2 years. I have never have a problem with them, I always forget I have them in and they make wearing lenses a lot simpler. They are great value for money, I used to pay over £200 a year for lenses, now I am paying a lot less.

Result is not guaranteed

These lenses simply don't work for me as my eyes get sore and red after only 4-8 hours of the continuous wear. It's simply impossible to wear them as long as one month in my case. Seem to be a good product but for some reason does not work in my case. Sad.

Honest Review. Love Love Love.

Ill start with the bad points:
Sleep in eyes for the first few days when you wake up.
Odd itchy day.
Odd bloodshot eye.
Other than this these are excellent. Waking up in the morning and being able to read messages etc on your phone and just being able to get going without putting in lenses is brilliant. I wish I discovered these sooner.
I cant even feel them in my eyes. I fotget they are there. I really love them.
I work in front of a computer all day and im back on the laptop at home most evenings and my eyes dont get dry.

What has happend with those contact lenses??

I have found the contact lenses much more comfortable to wear than my glasses.I use the monthly coopervision contact lenses from begining which is about 20 months and they were great. Unfortunately from few months they get worse, they were cracking after two weeks of wearing them and it has hapend with at least one pair from every package. What's happend with my contact lenses??

Very disapointed

Bought these lenses purely on the good reviews. Expected good things! I could not bare these lenses any longer than four days. Tried removing cleaning and reinserting the next day but scratchy feeling came back within a few hours. Reverted to daily disposables.

Not good for continuous use

My eyes have always been very sensitive, after reading all the good reviews i decided to buy these lenses. On my first day they felt great, comfortable and i didn`t feel them in my eyes. After 8 hrs my eyes got very tired , sore and dry so i had to use lots of eye drops....however, I decided to leave them in and see how i felt in the morning. When i woke up next morning, my eyes were sore with a burning sensation. So unfortunately these lenses are not good as a continous wear for me. They would make great daily ones. I will keep searching for the perfect lenses for me.

I totally agree with everyone -- these contact lenses are amazing! I can`t feel them in my eyes , they do not dry out and my eyes look white and healthy!
I would strongly advise buying these lenses!

Ok so I raved about these when I first bought them, but I now find myself constantly wetting my eyes due to them feeling uncomfortable and dry. They seem to dry out quickly after just putting them in, and easily throughout the day, which is a shame, because extended wear contacts were a godsend to me over laser eye surgery...and they were within budget too.
Im at a loss which ones to try next...mabes the Night&Day ones, or even the cheaper ones as the reviews sound just like my experience now...I have to try something!!
I would still use extended wear however, of any brand, even with the constant wetting.

Most comfortable lenses ever!

Having worn contacts for years (hard, gas permeable, daily soft) I`m finding the Biofinity continuous wear lenses the best ever. I wear them at night and my eyes never feel dry or irritated. It is as if there is nothing in my eye. My daughter also thinks they are great and says that she won`t bother with Laser eye surgery when lenses are so comfortable.

Great Lenses

I have worn contacts for over 15 years and always purchased 2 week disposables. After finding this website I decided to try the extended wear Biofinity lenses. With my schedule, and a new baby, I had a hard time taking out my contacts every night, so I thought these would be better for my eyes. Let me say that they are wonderful! I have fallen in love with these lenses! They feel good, they dont cloud up as easily as others that Ive tried, and I dont have to take them out for 30 days. I couldn`t be more pleased with my purchase!
