Varifocal contact lenses work with their two or more prescription lense features in a single, small lense. This progressive lens will adjust your vision level so you can see anything from varying distances to wearers. This medical device makes the whole seeing process easy for everyone. The most amazing part is that with the help of varifocal contact lenses, you can see in any situation without any additional need for eyewear.
There are more things to break down to make it clear how do varifocal contact lenses work. Let’s have an in-depth overview down below.
What is a varifocal Contact lens?
A varifocal contact lens is a kind of contact lens that has multiple prescriptions in a single lens. It helps to correct refractive errors like presbyopia. People with presbyopia need to wear contact lenses and glasses simultaneously as their vision changes frequently.
A varifocal contact lens makes the process easy because it has three features. These multiple prescription lenses solve the problem of seeing close objects, objects that are viewed at a distance, and seeing everything in between.
This little lens has multiple visions, making your view clearer and more accurate. People who use glasses know how tough it is to wear them all the time. You can’t wear them in the rain, while playing, at some events, etc. That’s why more people are switching to contact lenses.
And the rate is getting higher day by day. Since 1991, about 4% of people are switching to contact lenses per year. And researchers are saying that the rate will increase more in the upcoming days.
When you have problems seeing things that are close or far, you can switch into contact lenses. But what if anyone has both problems at the same time?
That’s why varifocal or multifocal contact lenses were invented. Now, everyone has the freedom to see clearly at all distances.
Now the question is, how do varifocal contact lenses work?
We all know how contact lenses work. Some of you also know how do bifocal contact lenses work. Varifocal contact lenses pretty much work the same just with better facilities. Some people find it easy and comfortable to wear initially, but on average, it will take four to six weeks to get used to them.
As time passes by, everything will get easier. You will get a better vision as your eyes will automatically look through the correct part of the lens. Also, you can read, drive or do anything without any additional glasses.
There are two types of varifocal contact lenses: Segmented vision and Simultaneous vision. They both work in different ways.
Segmented vision contact lenses
This design is more like bifocal glasses. Bifocal contact lenses have two vision features. Moreover, it works on close or distance vision problems at once. Like Bifocal contact lenses, Segmented varifocal vision also has solutions for those two problems. It just works differently. Segmented Vision has its top or middle segment to see the distant objects correctly. And the lower segment solves the problem for closer vision.
Simultaneous vision contact lenses
Simultaneous vision works for both bifocal and varifocal contact lenses. Usually, this design consists of two or more concentric circular zones. The center of the lens controls the near refractive or distance power. Multifocal lenses can be a CN ( center near) or CD ( center distance ) design. These concentric circles offer various lens power for different viewing distances.
Importance of Varifocal contact lenses:
Varifocal lenses are essential for people who have astigmatism and presbyopia.
Astigmatism is a sight problem that causes blurry and detrended vision at any distance. It happens when the eyes fail to focus light evenly on the retina. Which also causes allergies and headaches. Life was pretty tough for astigmatism patients.
Some of you have heard about astigmatism contact lenses and the know-how do astigmatism contact lenses work. Now let us tell you that astigmatism, Bifocal, and varifocal contact lenses are all the same. With the blessings of varifocal contact lenses, they can also enjoy the perfect vision.
Before the invention of varifocal contact lenses, astigmatism would develop into presbyopia after age 40. Presbyopia is a disorder that decreases the ability of the eyes to focus on nearby objects. So people needed to use contact lenses all the time and carry reading glasses, which was uncomfortable. Varifocal contact lenses work for both astigmatism and presbyopia patients as a blessing.
Also, they come in different color contact lenses. How do color contact lenses work? It doesn’t do much; it just helps people suit their personal preferences. So overall, we can say, varifocal contact lenses help with the most precise view and the dream look. Last but not least, you can see anything in any situation without extra eyewear.
Disadvantages of varifocal contact lenses:
It’s kind of tough for new people to adjust varifocal contact lenses in the beginning. Also, the costs are high, especially if you need different measurements, complex design, unique colors, and required fittings.
FAQs
Q1: Are varifocal contact lenses worth it?
Answer: It’s beneficial for people with more than one refractive error(a type of vision problem). It will help you have better visual acuity to see near, medium, or far distances, without any other glasses. That’s why varifocal contact lenses are worth it to some people.
Q2: Are Multifocal contact lenses and varifocal contact lenses the same?
Answer: Multifocal contact lens is another name of varifocal contact lens. They are also known as progressive lenses. How do progressive contact lenses work? The same as varifocal. Progressive lenses, multifocal contact lenses, or varifocal contact lenses work for presbyopia and other sight-related problems.
Q1: Can you use Varifocal contact lenses as monthly contact lenses, and how does it work?
Answer: Varifocal contact lenses are safe to wear every day at any time. So you can wear them as monthly contact lenses. Most of us know how do monthly contact lenses work; you can all wear varifocal contact lenses and keep them in solution before sleeping. You can also go for disposable contact lenses. After 12 hours, you can just throw them into bins.
Final thoughts
Ultimately, we can all agree that varifocal contact lenses are a blessing of technology. Millions of people can see the world now. Varifocal contact lenses are working as perfectly as possible. And we also know that it will be more helpful and provide the best service in the future. Finally, many people can cut off glasses from their life and still have a clear vision of near or distant objects.
