Bifocal contact lenses are specifically designed for people suffering from an eye condition called presbyopia. If you are holding that menu at arms length tofocus clearly, you might be suffering from presbyopia. Other symptoms might include blurred vision, headaches, eye strain and eye fatigue.
How do BifocalContact Lenses Work?
Like bifocal eyeglasses, bifocal contact lenses have two powers on one lens: one to correct distance vision (hypermetropia) and the other to correct near vision (myopia), helping you see clearly atboth distances.
Various types of bifocal contact lenses are available and the type that is right for you depends on your lifestyle and amount of correction needed. Your eye care professional will help you with making the correct choice for you. Here is a closer look at some of the the various bifocal contact lens designs available today.

Aspheric multifocal contact lens (also known as progressive contact lens) designs work more like progressive eyeglass lenses, that is different prescriptive powers are located across the lens letting you see clearly at all distances. These lenses do require a period of adjustment, the eyes eventually learn to ignore near objects when focusing on far objects and vice versa. |

Concentric contact lenses (also known as annular contact lens) have an arrangement of prescriptions in a bulls eye pattern in which they are alternate in strength from near to far. Depending on your eye care needs the centre of the lens can either be designed for near vision or far vision. |

Translating bifocals contact lenses work much like bifocal eyeglasses. There are two distinct prescription areas, one for near vision and the other for far vision. Depending on your visual needs the lens can have either near or far vision at the top or the bottom. Contact lens tend to rotate when you blink, to avoid the lens from rotating the bottom is weighted (ballasted) and/or flattened (truncated). This helps to keep the lens in the proper position |
