For a general understanding:
In a Reinigunsflüssigkeit include two factors of major importance:
1. The ocular tolerance
2. cleaning performance
The dilemma is: the better the cleaning performance, the more "aggressive" is usually the solution and therefore worse tolerated. So it is important to find a mix "optimal" (note: people react individually and compatibilities are different from person to person). During the time I had with AquaCare within 3 years 3x "infection" of the eyes, which could however be treated quickly because of direct reaction. That there is a connection with the Reinigunsprodukt here is close, but can not prove, of course. Anyway, I had prior to use with this fluid never had problems with the eyes, as I clean the lens properly.
Interested parties should definitely by Stiftung Warentest googling times and look at the results, several products were tested. HOWEVER: I did the test is understood to Stiftung Warentest has tested just 5 minutes exposure solely at Aqua Care, as it is declared on the packaging as a minimum requirement. If the really were so, the result would obviously not meaningful, I have my lenses still overnight in lens case. Maybe someone here knows so more and has at Stiftung Warentest might demand times ?!
Anyway, I'm switched to Opti Free Replenish. This was for me the results of the best "fit" because the damage to the cell structure was only "medium" (AquaCare "low"), but the Reinigunsleistung was very good. However, the price is outrageously high, I do not, however, the health of my eyes worth. Habituation my eyes, however, has taken a couple of weeks and the change was not so nice. I think the wearing time is longer at Optifree, but the comfort in AquaCare was better (but unfortunately not the main purpose given: killing harmful bacteria to the eye).
I hope I could help some with my review.
PS: A not mentioned impudence of solo AquaCare is still that for ages the bottles are sold with lids that are not closed after opening and one on the road has no density bottle. An absolute impudence ..
