What is LACREON

Hello,

I have recently switched to 1-day acuvue moist from focus dailies. I will say the acuvue are a much more comfortable lens. Cost twice as much but that is worth it.

I cannot find an answer to: What is Lacreon?

All I can find is the marketing phrase

Quote:

*LACREON™ is Johnson & Johnson Vision Care, Inc.'s brand name for its proprietary technology that permanently embeds a water-holding ingredient, similar to that found in natural tears, into the proven etafilcon A material.

What is the water-holding ingredient and is it coming off the lenses and into my eyes? If I have to store a pair in cleaning/disinfecting solution over-night and wear them again does the "water holding agent" get diminished, rinsed away?

Technically, these are ONE day contact lenses. You really shouldn't be cleaning them overnight or wearing them for more than a day. But I know that many people do.
Based on what I've heard about this Lacreon® it's permanently embedded in the lens. Therefore, no matter what you do to it, it's always going to be a part of the lens and cleaning or storing should have no adverse effects.
I'm not a doctor though and you should always check with a professional.

Thank you for your reply.

Yes, I realise its not ideal to wear these contacts for more than one day. I do not do it as a matter of course. But as somebody who has worn contacts for years, I know it does and will happen.

Its good to know that the "moist" is not a coating that wears off. I was concerned these lenses had some sort of lubricant on them that was washing off every time I blinked and going into my eyes. Who knows what the long term affect of something like that would be.

I am very happy with the 1-day acuvue moist lenses. I wore focus dailies for years and acuvue's are so much more comfortable.
