Bausch & Lomb Purevision Multifocal is a product designed for all those, who suffer presbyopia – a condition, in which you are not able to see things clearly from a short distance. It is quite common and natural among people who reached 40 years of age. But, just because you have presbyopia it doesn't mean you need bifocals or reading glasses or in fact any glasses at all. Purevision Multifocal contact lenses feature an innovative optical design allowing you to see clearly at all distances – near, far, and everywhere in-between. Thanks to AerGel and new generation silicone-hydrogel material these monthly contacts are very comfortable.
