Multifocal Lenses

As we age, the ability of the lens to focus light rays from objects from the far distance, or near to us becomes poorer. This affects spectacle and contact lens wearers, as well as people who previously did not need glasses at all.  By the time we are about 40-45 years of age, there is a need for a separate correction for distance and near tasks.

Multifocal or Progressive contact lenses allow you to see clearly in the distance and up close, as well as in between meaning that reading glasses, which are often inconvenient and easily misplaced, are no longer required.  These lenses allow you the convenience of being able to see across a room, as well as being able to view your computer or to read a book comfortably (Acuvue, 2013).

These lenses all have a slight compromise compared to our natural ability to focus on both near and distance objects, and work by placing both distance and near refractive error correction areas in front of the pupil.  The brain then selects the image appropriate to the distance of the object the eyes are looking at.  These lenses, whether soft or rigid in design, are more complex and may take longer to be fitted than basic contact lenses.

With advancements in technology, new designs are becoming available every day, meaning that most people are now able to wear contact lenses, even those who have tried unsuccessfully in the past.
