Purevision Multifocal Contacts

Find information on Purevision multifocal contacts and where to buy at the best price.

When I started researching bifocal contacts with a view to what I might need later in life, I was surprised to read about multifocal lenses that can have two or more different prescriptions within each lens. How do they work? How can the eye look through two or more different powers at the same time?

My page on multifocal lenses explains things in more detail but one of the most popular types of multifocal lens is an aspheric lens where several different powers are laid in circles within the contact lens. Somehow, the eye learns to switch between the various powers to focus on near or far objects. The picture below shows how this works.

Purevision multifocals are aspheric lenses made specially for people with presbyopia, a condition that sadly affects many of us as we get older and have difficulty focussing on reading small print or doing intricate work like sewing without getting blurry vision.

They are the only multifocal lens available in a silicone hydrogel material called AirGel and allow the eye to instinctively find the right zone in the lens for correct focus.

Tip: My optician told me to read small print in bright light to avoid straining the eyes as I get older. That was fine five years ago, but now that I'm in my 50s, I have tried bifocals too!

How Multifocal Contacts Work

How Multifocal contact lenses work How the eye instinctively reacts to switch between the lens powers to see near and far.

Presbyopia can affect you as you get older even if you've never had to wear eye glasses or contact lenses for vision correction before.

Aspheric multifocal contacts work by using several different powers within a contact lens laid in concentric circles which radiate out from the center of the lens.

When doing close-up work like reading or sewing, your eye focusses through the middle of the lens; when driving the eye looks through the outer portion of the lens; and for doing work like surfing the internet, it focusses more on a mid point, roughly in the middle of the lens.
