Not trying to shit on dailies by the way, as they're actually the healthiest for your eyes if you can swing the cost.
>The reason behind the lawsuit? The suit claimed Johnson & Johnson had misled consumers and eye doctors that their Acuvue 1-day lenses had some type of special physical property that limited its use to 1 day when, in fact, they were identical to regular Acuvue lenses, which were bi-weekly contacts.
