Bifocal and Multi-Focal Lenses are two different kinds of contact lenses that can both be worn by people who suffer from a condition called Presbyopia. Bifocal Lenses are manufactured using soft materials, or rigid, gas-permeable materials. Some of these lenses are also available as soft, disposable lenses. Where Bifocal lenses have two frames for two different prescriptions, Multi-Focal lenses have a range of powers in each lens. Bifocal and Multi-focal lenses are available at VisionDirect.com at affordable rates. If you are looking for Bifocal or Multi-Focal Lenses, brands such as Acuvue, Focus Dailies, and Progressive products are available at VisionDirect.com along with attractive offers. You can choose multiple pairs depending on how many lenses you want per box.
