The addition (ADD) is not indicated in these contact lenses, as it is for other multifocal contacts. The manufacturer states that these multifocal contact lenses are intended for wearers with an addition of up to +2.50. If the addition is required, the distance value is adjusted for both eyes. Please note that these contact lenses should not be ordered without a consultation with the optician. CooperVision’s Proclear 1 day multifocal lenses guarantee perfect vision at all distances, making them ideal for presbyopia correction. They are made from Omafilcon A, a material that ensures the eyes stay hydrated throughout the day.
