Breathing Air Optix Night & Day Aqua

Since these lenses have the word "air" right at the beginning of their name, can I take that to mean that your eyes get plenty of oxygen while you wear them?

As far as I remember it lets 5 or 6 times more oxygen through, thats why you can sleep in them. Best lenses I've had.

Five or six times more oxygen than what?

I'm glad you like the Air Optix lenses.

Hi. The air Optix lets 5 to 6 times more oxygen through than normal soft lenses. All good for comfort and the health of your eyes.

Probably five or six times more oxygen than the Leading Brand, whatever brand that may be.

Thanks Pandy. Do they feel very different from other contacts you've worn?

Interesting question.

As I've worn lenses for so many years the soft monthly ones (can't remember brand) were getting to be a pain and I would get to the point in the day, get them out! The young optician was a bit 'sales pushy' but basically said 'you'll never go back after night and day ones'.

He was right, as soon as I tried them it was like OK, nice...lets see how they are hours from now...how are they? Glad you asked, forgot they are still in this late in the evening. They are so comfortable, in the main you really do not 'feel' them. So in answer they feel like a comfy pair of old slippers you can wear and wear not like the other lenses that felt like I was wearing 4" high heels!

Can't you tell I like them?

I like your slippers/heels analogy, Pandy. I think I understand your point. Do you think these are 4" high heels?

You mean "killer heels," right? Otherwise it would be kind of an oxymoron, don't you think?

Yes, that's right. "Killer." "Heals." Oxymoron. I don't know if any killers that heal.

Haven't you heard of antivenin? It's something given to snake bite victims that's actually made of snake venom.

That's not the point, really. The point is that someone wanted to know how much air your eyes get while wearing Air Optix Night & Day Aqua.

Hear that? That's the sound of our Geek Alert getting a hit.

here's a thought...YES oxygen is important but don't you think having a healthy tear film better for soft contact lens wear?

Soft contact lenses fall into 4 material classes split into 2 categories.
hema hydrogel, and silicone hydrogels.

hema hydrogels are affected by protein deposits and silicone hydrogel lenses are affected by lipid deposits.

Depending on a patients eyes and tear film they may not be suited for silicone hydrogel lenses.

Over all silicone hydrogels deliver higher amounts of oxygen but high water content hema hydrogels can also deliver higher amounts of oxygen as well..

the "high" oxygen advertising is a marketing ploy as well.

So what's wrong with saying that soft contact lenses have high oxygen permeability? They do, don't they? I don't know if that's better than having a healthy tear layer or not. All I know is I've never heard of anyone dying because the didn't have enough tears.

not all soft lenses transmit high oxygen levels compared to silicone hydrogels.

So you're making a claim of false advertising?
Not that I disagree, I just want to make sure I understand where you're going with this.

alot of companies use the "lack of oxygen fear" to promote their lenses, however its always healthier to wear a lens with the highest oxygen permeability.

So are you saying there's something wrong with the "lack of oxygen fear"? If your eyes are lacking oxygen because of the contact lenses you wear, then there is a reason to fear, is there not?

What do you mean by that? What is the "lack of oxygen fear"?

"lack of oxygen" is the new marketing buzz word promoting contactlens wear in a market that is worth billions world wide.

Yeah, but what does it mean? It sounds like a good reason to wear glasses.

the oxygen issue is def open to debate but the medical research that is available the research is pointing towards wearing contact lenses that promot high oxygen exchange such as silicone hydrogels, and hyper permeable rgp's.

true that eyes need alot of oxygen but even hema soft lenses with 55% water content will produce gas exchange so its. Not all eyes can wear silicone hydrogels lenses due to lipid deposits.

Don't most soft lenses have pretty good oxygen permeability? What's "good" permeability anyway? 50%? 75%? 95%? At what point does "fair" become "good"?

Low Dk is < 12
Medium Dk is 15-30
High Dk is 31-60
Super Dk is 61-100
Hyper Dk is > 100

So I guess "fair" becomes "good" at around the 30 mark.

I suppose even if a lens allows 99% of available oxygen through, you can still technically say that there's an "oxygen deficiency."

Yes, I suppose a 1% reduction on oxygen flow can be called a "deficiency."

So it follows that a lens with >31% oxygen permeability.

"Oxygen permeability" is defined on Wikipedia as "the ability of the lens to let oxygen reach the eye by diffusion." Wikipedia also goes on to say that "typical values are from 25 to 50."

So, typically a contact lens has medium to high oxygen permeability.

RejZoR · #31 (**permalink**) 05-07-2012, 01:36 AM

It all boils down to the material used for the contact lenses. With hydrogel, you can't ever achieve Dk of more than ~40 afaik. You could probably get there or slightly past using very thin lens and very low water levels but that would make them very uncomfortable, problematic for dry eye users.

If it's silicone hydrogel, reaching Dk of 100 and above really isn't that problematic and i think they are comparing their contatcs with hydrogels.
I mean, if you multiply usual hydrogel Dk value with 5 you get Dk of 125. Thats about what AirOptix Aqua are advertised. And if you compare high breathability hydrigels with Night & Day (again multiplied with 5) you again get around the value AirOptix Night & Day are advertised.
