These are soft contact lenses that correct vision for individuals who require a different lens correction for their near vision and their far vision. Basically, if you wear bifocal glasses, then this is an option you could consider.
There are now several different types of soft bifocal contacts available. We find that different brands work for different individuals. We put the contacts on your eyes to determine how well they fit the eye, and how well you see with the lenses. If one type does not work, we try a different brand.
There are disposable brands available. Also, some are designed for "extended wear" so you can leave them on at night.
