The difference between bifocals and varifocals
Let us now compare the two types of lenses.
As a result of their single vision appearance, varifocals may be more aesthetically pleasing to wearers. They will also provide a more comfortable viewing experience once they are accustomed to them.
Bifocals are generally more affordable and offer two distinct prescriptions; they are a great option if you are purely seeking function.

Who requires varifocal lenses?
One of our most important senses is sight, and 78% of respondents to a survey stated that they feared losing sight the most. However, it is inevitable that we will eventually experience deterioration of our sight. As a result of the loss of near focusing ability that occurs after the age of 40, a varifocal lens is generally necessary for those over the age of 40.
We lose elasticity and stiffen the crystalline lens in our eyes as we age, causing our close sight to deteriorate. As we age, our eyes lose the flexibility that allows us to focus on different distances. As a result, your vision may begin to blur when you look up at close objects due to weaker muscles around the eye.
It is commonly referred to as presbyopia, and you may begin to notice it in your early 40s. Varifocal lenses are often used to treat presbyopia, allowing you to see clearly at all distances again.
