Multi-Focal and Bi-focal Lenses
Do you have trouble seeing that small type on prescription bottles, or reading the gps on your phone? If so, you probably have a common age-related condition called presbyopia which happens when the lens loses the ability to focus on close objects. If you have presbyopia, you are not alone. Fortunately, there are options for presbyopia. Bifocal and multifocal contact lenses allow you freedom over glasses and the ability to see in all directions. They are available in contact lenses in both soft and Rigid Gas Permeable (RGP) varieties.
The Difference Between Bifocal and Multifocal Lenses
Like bifocal lenses, progressive multifocal lenses allow you to see clearly at different distances through one lens. A progressive lens gradually changes power from the top of the lens to the bottom, giving a smooth transition from distance vision to intermediate/computer vision to near/reading vision.
