The progressive lens is a
multifocal lens that is the most accommodating
multi-distance vision for presbyopia patients. The first
progressive lens was introduced in
1959 by Bernard Maitenaz.
As the name "progressive" indicates, the progressive lens progresses
an RX prescription from a near prescription leading to
the distance prescription including every prescription
in between. Cosmetically speaking, progressive lenses are
the most aesthetically pleasing multifocal lens by
making the progression of prescriptions virtually
seamless and showing no immediate evidence of multi
prescriptions on the lens to an onlooker. |

The progressive lens has a visual field anatomy
of an hour glass (see image below). The two dominant
prescriptions (distance and near) have a wider field of
view. The progression in between has a narrow field of
view leaving a peripheral distortion.

There are premium progressive lenses
to help minimize peripheral distortion. Wave front
technology was introduced to spectacle lenses as a way
to minimize overall distortion. Wavefront is commonly
used as a diognosis of the eyes Freeform progressives
have also been introduced as a new technology. By
placing the ADD power and entire prescription on the
back of the lens freeform lenses claim to eliminate
front curve distortion. By eliminating front curve
distortion the freeform design considerably increases
all visual fields of view including the intermediate,
hence minimizing peripheral distortion. |
