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.

Used for years

I do not find it easy to remove lenses so having the continuous wear option is great for me. These stay moist inside my eyes for the entire month - I change them every 4 weeks and have had no problems whatsoever.

Excellent contact lenses

I’ve been wearing these lenses for over 10 years now. They are the most comfortable I’ve had, even after sleeping in them for up to 3 weeks. I feel they do get dry at the end... but I haven’t had lenses that don’t feel like that? Exceptional performance in comparison to any other lense I’ve tried.

Great product

These lenses were recommended by my optician as they make your eyes feel less dry and I would have to agree this would be the case. The website delivers promptly and I have never had any issues. I would highly recommend them.

Biofinity contact lenses

I have used Biofinity contact lenses for several years now. I disliked dailys and moved to montlys to reduce the number of times my hands are in contact with my eyes. I tried other brands first but regularaly had to take them out before 2 weeks due to irration / sensation of scratching. No such issue with Biofinity and I always get a full month from them before taking them out. Great price also.

Long wear gets dry

Overall it's pretty comfy but when you wear it for more than 8 hours it starts getting dry.

Great lenses! Never had any issues with them at all. I find that these do not fray out at all and are very soft. Always great delivery times aswell.

A quality product at a decent price

I’ve tried many contact lenses types in the past 6 years and these ones by far came out on top for comfort throughout the day and easy cleaning and storing ready for the next day’s use.
The price is good too, I recommend these to anyone unsure about which lense to go for

Great lenses for full time wearers

This is a really comfortable lens that I wear for sixteen hours a day - every day. What else to say, it just does the job it's supposed to without any fuss. Strong and hardwearing too, being very forgiving of occasional "rough" handling.

Great lenses

I love these lenses. Sometime I have had them in for 5/6 weeks without even realising! They are so comfortable i can hardly feel them. I recommend them to everyone and won't go back to using dailies.

Great continuous wear lenses

I have high myopia (-10) and have been using this brand for years with absolutely no problem at all. My optician refers to these as the gold standard which works for me!!

These are very good contacts. They are easy to fit and are super thin. Easy to maintain and when in the eye they are not noticeable at all

Crystal 1 day contact lenses

A great (and cheaper) alternative to some of the other one day lenses - couldn't tell the difference.

Pretty decent

My eyes are somewhat on the sensitive side, unlike some other brands I've tried I usually get the full months use out of these (approx 13 hours per day).

Easy and comfortable

I have worn these lenses for a while now, they are very comfortable and long lasting. They feel as good at the end of the month as they do at the beginning.
