How do multifocal contact lenses work?
Who are they for?
Multifocal contact lenses are most commonly used to treat presbyopia,
which is caused by the eye aging. In the past if you had presbyopia
your only option was to use reading glasses to look at objects close
up—like a book, computer screen or restaurant menu. But now multifocal
contact lenses are available that allow you to see nearby objects as
well as those in the distance with clarity—and you’ll never need to wear
If you are over 40 years of age, multifocal
contact lenses could be very useful. Many people use them to enjoy
outdoor activities like sports, riding a bike, jogging, and going to the
gym. Others simply find glasses cumbersome.
How do they work?
contact lenses are exactly what they sound like: lenses with multiple
prescriptions all-in-one. Commonly there is a prescription for looking
at close objects, a prescription for looking at objects in the distance
and sometimes even a number of prescriptions for in-between distances.
Basically, multifocal contact lenses allow you to see at various
distances using one type of vision correction that has different lens
powers. They share a lot in common with progressive glasses.
multifocal contact lenses work depends on their design. Three common
designs are concentric vision, alternating vision and simultaneous
Concentric multifocal contact
lenses are the most common way to treat presbyopia. They work by using a
number of concentric circles with different lens power prescriptions
for different distances.
alternating multifocal contact lenses your pupil shifts between the
different lens powers as you look up and down. They have separate areas
in the lens for near and distance vision. Similar to bifocal glasses,
alternating multifocal contact lenses have a top section that is used
for distance vision and a bottom section for near vision. This is so you
can easily ‘alternate’ from looking straight ahead at objects in the
distance to looking down at a book or phone screen.
simultaneous vision contact lenses, the near and distance vision
sections are both positioned in front of your pupil. Your eye looks
through different lens powers at the same time and your brain chooses
the correct power for the object you’re looing at.
