Everything You Need to Know About Multifocal Contact Lenses
The world of multifocal contact lenses can be rather overwhelming – and that’s an understatement!
But fear not; you are in the perfect place to find out everything you need to know. Get ready for the simplest possible breakdown of multifocals.
What are multifocal contact lenses?
How do multifocal contact lenses work?
For people who wear contact lenses, having to switch between multiple pairs for different settings can be inconvenient.
Fortunately, multifocal contact lenses solve this problem by allowing wearers to see clearly at different distances with just one pair of lenses.
This allows for a smoother transition between different environments, such as going from reading a book to driving a car.
Multifocal or varifocal contact lenses are a great option for those who want convenience and ease of use while still maintaining clear vision.
Its important to note that this transition may not always be perfect and may take some getting used to. This is an important factor to discuss with your optometrist when getting fitted.
Aspheric vs concentric - which multifocal lenses are right for me?
It is important to note that there are two types of multifocal lenses available, aspheric and concentric.
Concentric ring design
Concentric circles vary in diameter, but share the same centre. Concentric ring design involves a central circular prescription lens and alternating concentric circles surrounding the central point.
The eye then alternates between the rings to see at different distances with a gradual transition.
There can be multiple layers of rings, two of which are usually within the pupil’s range. This range varies as the pupil contracts and dilutes according to the levels of light.
Concentric ring lenses are available in both soft and hard gas permeable materials. However, the location of the prescription will vary according to the material.
A hard or rigid gas-permeable lens features the long-distance prescription in the central point of the lens.This is referred to as the centre-distance.
A soft contact lens will comparatively place the short-sighted prescription in the centre of the lens. In this case, the prescription is known as the centre-near.
It is also possible to have a central near-sighted prescription in the dominant eye and a long-sighted centre for its non-dominant counterpart.
DID YOU KNOW?
Varifocal contact lenses work by combining multiple prescriptions in each lens, allowing the wearer to see clearly at both near and far distances without having to switch lenses.
Aspheric design in multifocal contacts is similar to progressive lenses in glasses, where the various prescriptions merge across a single lens.
Aspheric lenses are designed to be flatter and smoother than traditional spherical lenses, which can result in sharper and clearer vision for wearers.
Additionally, they can provide a more comfortable and natural fit, reducing the chances of irritation or discomfort.
Aspheric lenses are particularly beneficial for those with higher prescriptions or astigmatism, as they can reduce visual distortions and improve visual acuity.

How to use multifocal contact lenses
Wearing multifocal contact lenses can be a daunting task, but with proper insertion, there is nothing to worry about.
To use multifocal contacts, it’s important to follow the instructions provided by your eye doctor and the manufacturer.
These may include proper cleaning techniques and a specific wearing schedule.
With some practice and patience, wearing multifocal contacts can become second nature and provide clear vision for all of life’s activities.
Choosing multifocal contact lenses: advantages and disadvantages
Multifocal contact lenses are not suitable for everyone. Read on to find out the advantages and disadvantages of using them.
You will no doubt be pleased to hear that multifocal contact lenses are available for various usage periods e.g. reusable multifocal contact lenses or daily or monthly multifocal contact lenses.
There are also options between soft and rigid designs to suit your personal preference. A key benefit is that you can get multifocal contact lenses for astigmatism.
This is a type of refractive error, meaning that the eye does not focus light evenly on the retina, resulting in blurred near and distance vision.
Those with astigmatism would often also develop presbyopia around the age of 40.
This led to a tricky decision: opt for wearing reading glasses on top of contact lenses or wear bifocal glasses. Thanks to multifocal lenses, clear, seamless vision is now achievable with much less compromise.
There are some disadvantages to multifocals that may mean they are not the right lens for you. Often there is hazy or shadowed vision early on in the adjustment process.
Multifocal contact lenses come at a higher cost compared to standard contacts. This is owing to the more complex prescriptions and precision required when fitting them.
The cost of varifocal lenses is an important factor in deciding your method of vision correction but ultimately it should be something that you speak with your doctor about.
