How Do Multifocal Contact Lenses Work?


Do you have trouble seeing far away as well as up close? You’re not alone, this is a common vision impairment. If you’ve started to lose your ability to focus up close (presbyopia), multifocal contact lenses might be right for you

42% of people have nearsightedness, and farsightedness becomes more common after the age of 40. These are different than presbyopia, where you lose the ability to focus on things closer, regardless of distance prescription.

Multifocal lenses are designed to combine prescriptions in one pair of contacts. This means no longer juggling multiple pairs of glasses or your sight hindering everyday life.

Now, here is closer look at what multifocal lenses are and how they work.

Are Multifocal Contact Lenses right for me?

Eyesight is constantly changing and at older ages it is common for things closer to us to become blurry and unreadable. This may also lead to headaches and strained eyes. If you already have a prescription for nearsightedness and you start to experience troubled vision closer to you, then multifocal contact lenses might be the answer.

What are Multifocal Contact Lenses?

There are many types of contact lenses, but these ones serve more than one eye prescription at the same time. This typically means a prescription strength for seeing things far away, and another one for up close vision. This prevents the need for contacts and glasses, or multiple pairs of glasses.

What’s the difference between Multifocal and Bifocal Lenses?

When talking about soft contact lenses they are effectively the same thing. The only true bifocal contact lenses are segmented bifocals, which are hard gas-permeable lenses.

How do Multifocal Lenses Work?

There are generally three types of multifocal contact lenses that work in different ways. These are concentric, aspheric and segmented bifocal. After an eye exam and depending on your vision, your eye doctor will decide which is the best fit. The technology behind multifocal contact lenses have progressed over the years and could really benefit your eyesight.

Concentric

These lenses work similar to a bull’s eye, where the changing prescriptions alternate in a ring like pattern. There are gradual transitions between the strength so your eyes can adjust naturally.

Aspheric

Aspheric multifocal contact lenses gradually adjust from distance power in the center, to nearsighted power along the edges. Rather than concentric, these typically only have two prescription powers.

Segmented Bifocal

Segmented bifocal lenses work similar to reading glasses. The bottom section of the contact lens is a prescription for presbyopia and the upper section is for seeing further away distances. Typically, the contact is slightly weighted to prevent shifting and these are available as hard lenses only.

Multifocal Lenses don’t work for everyone and it’s important to find an option most comfortable for you.
