PureVision is a soft contact lens family, and four boxes from it are stocked here. All four are six packs. The line covers single vision correction as well as options written for presbyopia, so most prescriptions naming this brand can be filled from this page.
With contact lenses you do not really choose. Your prescription does. It names the exact lens, and it carries the numbers that have to match: power, base curve and diameter, plus an add power for a multifocal lens. Swapping to a different box in the same family because the name looks close is not something to decide on your own, since fit varies between designs even under one brand.
What is worth checking before you order is that the box in your cart matches the box on your prescription. PureVision and PureVision 2 are different lenses. Multi-Focal and 2 for Presbyopia are both written for near vision, and they are not the same product either.
Contact lenses require a current, valid prescription from an eye care professional, and prescriptions are verified as part of the order. If yours has expired, book an exam first. If you are wondering whether the lens you have worn for years is still the right one, that is a conversation for your next visit rather than something to settle at checkout.
Quantities are per box and per eye. If your two eyes have different numbers, order the correct box for each eye separately, and check both lines before you pay.
