Biofinity Advice

Do we have anybody here on the board who wears Biofinity contact lenses and is willing to share their wisdom and insight with us? Thanks.

Sindyr · #2 (**permalink**) 11-09-2008, 08:09 AM

I just started wearing contact lenses 2 weeks ago. I just got 4 boxes of Biofinity lenses. Since it's the only lenses I have worn, and I am not a long term wearer I can't really give a comparison to any. So far I can say they seem fine for me and have been comfortable so far and I hope they continue to be so that I don't have to return them.

I`ve been wearing lenses for about 8 years now and I first tried continuous wear over 2 years ago. I have tried most brands but there is absolutely no doubt that Biofinity are much, much better than any other continuous wear lens on the market at the moment. If you have sensitive eyes do not look elsewhere. My eyes tend to dry out a lot - I work with a computer for most of the day and smoke cigarettes which does not help and Biofinity are the only lenses that can deal with my lifestyle. No dryness, itching or soreness for a whole month. You can easily forget you got them in at all. THANK GOD FOR THESE LENSES!

Hi Sindyr,

It's been quite a while since you've posted this, and we haven't heard from you since. I hope your Biofinity contact lenses are still comfortable for you.

Do you speak from experience, or did you just copy and paste a paragraph from another website?

Glad to hear it, boogi. How long have you been wearing Biofinity?

I've been wearing Biofinity lenses now for 2 months. I used to wear Coopervision Omniflex yearly lenses with 70% water. My optician persuaded me to go monthly with these high oxygen permeability lenses.

The first pair of lenses were the optician's re-branded lenses (identical to Biofinity) and I had some minor problems because the prescription was 0.25D out in one lens.

I also found my right eye a little uncomfortable (but also sometimes felt this with Bausch & Lomb Soflens Daily, which I had tried occasionally and the Omniflex lenses). This discomfort was not present outside however.

It seemed to take me 1-2 weeks to get used to these lenses, which did surprise me.

The second pair I bought as a trial to check the 'corrected' prescription. They were proper Biofinity lenses. I found these to be very comfortable in both eyes and I also felt/imagined the lenses were thinner than the original re-branded lenses. However, Coopervision assured me the two differently named lenses were the same, although there could be minor differences within manufacturing tolerances.

It is of course possible that it just took a little longer to get used to these lenses.

I have found that the lenses are easily damaged - just minor nicks on the perimeter of the lens, not a fatal radial tear, etc. My new optician has told me that, because I pinch the lens off the centre of my eye, I could damage/crease the lens if they are dryish, after say 17 hours wear (even if my eyes don't feel dry). She will show me an alternative removal method next week. She also said that the twin basket barrel lens cases are worse for damage than the twin side by side lens cases and I only noticed this damage when I switched to the barrel case, which I prefer.

I am in the process of ordering regular RGP lenses to try (for minor astigmatism correction/slightly better vision hopefully). If these don't work out, then I'll be back to Biofinity lenses, which I find very comfortable.

What was surprising about a two week adjustment period? Was that longer than you expected or shorter?

Well I thought (perhaps naively) that after so many years with yearly lenses the silicone hydrogel lenses would be very similar in feeling. It's not like I was going back to hard lenses or RGP lenses (which I am about to try

)

I did try Bausch & Lomb Soflens Dailies when I tore a yearly lens on holiday recently and had forgotten to pack a spare. That lens was very thin and very flexible, so handling was fiddly, but otherwise very little difference.

But of course the Biofinity is quite a different material.

I have been wearing the Biofinity lens for a few months now and they are the most comfortable soft lenses I have ever worn. I have been wearing soft lens for about 35-40 years. I was probably one of the first soft lens wearer in the U.S.. But the best feature is that it is very evident when these lenses are inside out. More than any other soft lens, you can immediately tell when one is wrong side out by the shape and the way it handles. I can't tell you how many times in the past I have had discomfort with a lens, only to finally figure out I had put it in backwards. They are very durable and I find no discomfort, even after 20 hours of continuous wear. And they cost about half of other brands. Great product.

Hello TELETINA500

Thanks for posting your experience with the Biofinity Lenses. I too find them very comfortable. I sometimes wear the lenses very long hours also but don't have any need nor desire to wear them 24/7.

Never ever had a problem with putting lenses in 'inside out', though some years ago, once did put two lenses in the same eye - but that was rather obvious

I didn't think Biofinity were particularly cheap, though Coopervision tend to undercut Johnson & Johnson on price and you do pay a premium for the high Dk silicone hydrogel lenses. There are some good prices on Internet Mail Order companies though.

Hi anu. Do you wear contact lenses yourself or just read the websites?

Thanks for posting. That's some good information. I hope KITT appreciates it.

i wanted to try biofinity, so i ordered from 3 different online distributors, but all 3 checked my prescription at walmart and would not send lens until i had a prescriptioin, very nice...... so i said, FINE, i'll get a prescription, i went to walmart OD for a refit from Acuvue oasys, to biofinity, i said i want to try biofinity, he said, ok, we'll order a trial pair, then he said what about Avaira, i said, no way, Dk/t is to low i want a higher Dk/t, besides biofinity is 3rd gen SiHy, completely different macromer from 1st/2nd GEN SiHy. he said, not really, i could not believe the walmart OD didnt know his contact lens polymers very well, biofinity is base on a new polymer, not the TRIS or Tanka polymer that 1st/2nd GEN are base on but a completely new polymer. so then i understand that OD really dont know the biochemistry of SiHy lens. same goes for MD's, i want very specific blood tests and i know what numbers i am looking for but sometimes MD says really doesnt work, so they dont know thier blood tests either, you know MD's and OD's are very general, i have to look out for my own well being, no one else will do that. because MD's and OD's surely dont have a freakin' clue.

Why did the WalMart OD suggest Avaira (a 1-2 week disposable lens) when you asked for Biofinity (a monthly disposable lens)?

There is not so much difference in Dk values in these two lenses at Dk 100 for Avaira and 128 for Biofinity, so although the Biofinity is better, you are probably approaching the rule of diminishing returns as the Dk value rises higher.

It seems that this site's sponsor is also a little confused about the lens material used in Coopervison Avaira lenses. www.lens.com states the lens material is Comfilcon A (same as Biofinity), whereas it is in fact Enfilcon A.

I might try avaira if biofinity is not as robust or does not retain moisture as well as the ads say. yes, diminishing returns on Dk/t, 90% compared to 98% not much difference. but i need to study the polymer structure and edge formation more, neither have surface treatments which is good, although avaira has 1/2 the modululs of biofinity, so that's a plus for avaira,

i need to read and re-read the original patents for comfilcon A and enfilcon A to determine the real similarities and differences between the two new polymers, and how they are different from the TRIS or Tanaka macromers.

I think at the end of the day, what matters is, does the lens feel good in your eye and is the oxygen permeability high enough for your planned wearing time?

You don't need to analyse the chemical polymer structure, etc. Even if you did, it probably won't tell you anything other than a rough guide about the comfort (unless you know you have an allergy to a particular polymer).

Hi Sindyr,

I guess you now qualify as a long-term wearer, unless you gave up on them two months after you posted this question. How is it going?

It's been almost a year since you posted this thought, boogi. Are you still comfortable with Biofinity? You're not going to change lenses again like you have so many times in the past?

Well, Sindyr, it's been about a year and a half at this point since we've heard from you. How do you like those Biofinity lenses?

That's very true, knotlob. That's a good way to trim it down to what's important.
