Multifocal &
Monovision
Multifocals
These are required when two different prescriptions
are necessary: one for distance, the other for reading. It is common
to need different strengths for different tasks from approximately
the age of 45. This common condition which affects everyone, is known
as Presbyopia.
Just like multifocal spectacles, multifocal contacts incorporate different
strengths within different parts of the lens. Some have reading segments
that resemble bifocal lenses. Others have ‘rings of alternating
power’.
Multifocal technology is constantly advancing and there is now a range
of manufacturers offering lenses in different designs.
The success of these lenses depends on factors including:
the
prescription
the
shape of the eyes
lifestyle
occupation
visual
demands
Some people get extremely good vision, while others find that they
sometimes have to use additional glasses for certain tasks. There
is a small but significant percentage of people who do not get on
with them at all and prefer to wear ordinary contact lenses to correct
general vision, and then wear glasses on top just for reading.
In order to assess potential suitability
and gauge their success it is advisable to book an assessment. The
optometrist will be able to give more specific information about the
likely outcomes and can arrange a trial.
Monovision
This is an alternative option to multifocals.
In monovision normal lenses are worn, but the power is modified so
that one eye is corrected for distance viewing and the other for reading.
Although it sounds strange it works very well, especially for those
under 55 and the success rates is higher than with multifocals |
