Acuvue Bifocal contact lenses can be a good alternative to your bifocal glasses. (It is though very important that you get to try out these lenses properly first at your opticians since it is impossible to convert the parameters for your bifocal glasses into the correct values for bifocal contact lenses.) The lens has five invisible, concentric zones which makes it possible to see clearly at varying distances – both far and near. Acuvue Bifocal has a flexible wearing schedule which gives you the options of either using the lens as a daily two-week lens where you take the lens out each night, clean it and insert it the next morning – or as an overnight one-week lens where you wear the lens constantly (day and night) for a week and then after 7 days replace it with a new one. It is also quite common to wear Acuvue Bifocal as a monthly disposable lens
