What are multifocal lenses? What does a multifocal lens do? Or do multifocal lenses really work? These are just some of the questions we’ll be answering today with this multifocal lenses post. So, if you would like to learn more about these types of lenses continue reading this post. 

If there is a lens that’s been getting great attention over the years it has to be multifocal lenses. One of the main reasons why this lens has been receiving so much attention is its use. In other words what it provides. Those who are familiar or have used this type of lenses will tell you that they offer the best of both worlds.

If you go with them, you’ll have clear long and distance vision without necessarily having to wear glasses. Even this wasn’t great these contact lenses are known to come in a variety of options. But before going deep into these, let’s look at what these lenses are.

What Are Multifocal Lenses?

Just by its name, it is evident that multifocal contact lenses are a type of contact lens. What isn’t evident is the fact that they are made using different lens powers. Yes, to give them their distinct feature, they are made using two or more lens powers.

What this does is help one see objects at all distances clearly. It is with this that some choose to refer it to as a single lens with multiple prescriptions. In general, these lenses are perfectly put together to give the wearer of the lens clear and un-blurred short distance view.

Who Uses Multifocal Lenses?

In most cases, this lens type is used by people with presbyopia. Also known as “Short Arm Syndrome”, presbyopia is a condition where one struggles with blurry vision. To be exact, it’s an eye condition where one experiences blurriness where doing near vision tasks like using a laptop or reading. Presbyopia is a common condition with people over the age of 40.

Why? Well, as we grow our eyes tend to lose the lens’ elasticity thus causing it to harden. As a result of this, our eyes lose the ability to focus on nearby or close objects given that light focuses now behind the retina as opposed to on top of it. Presbyopia is a natural condition and it is known to gradually increase as one grows older.

How Does Multifocal Lenses Work To Help With This Condition?

One way you can be able to deal with presbyopia is using multifocal contact lenses. What these lenses do is provide vision correction for short distances. A big plus with this particular lens is the fact they can accommodate multiple prescriptions on one lens.

What this result in is helping one see clearly objects that are at different distances. Key to note with multifocal lenses is that they o have three focal points for distance, reading and intermediate correction.

Types of Multifocal Lenses

Now that you are familiar with multifocal contact lenses, what’s used to make them and the condition it helps with, it’s time to look at the different types of multifocal contact lenses. The two types will be looking at in detail are;

  • Aspheric Multifocal Lenses
  • Concentric Multifocal Lenses

Aspheric Multifocal Lenses

This type of lens provides a nice blended transition between multiple prescriptions. When it comes to build, they are built like progressive eyeglasses lenses. With this lens, the near prescription or distance is at the centre. This tends to gradually change when you start moving outwards.

In terms of examples, Proclear 1 Day Multifocal contact lenses and Dailies Total1 Multifocal are examples of commonly purchased aspheric lenses. These two are normally weighted to remain in a proper orientation. This goes to ensure that there is clear vision correction all day long.

Concentric Multifocal Lenses

This multifocal contact lens incorporates concentric circles on the lens to offer a great vision. For it to work effectively, it has a gradual transition between prescriptions. Similar to a bull’s eye pattern, the rings tend to alternates distance and near corrections. A popular concentric contract lens is The 1 Day Acuvue Moist Multifocal lenses.

In Conclusion

After going through the information shared above, I am sure we can all agree that multifocal lenses do work. They work to help individuals over the age of 40 have clear and un-blurred short distance view.
