Varifocal Glasses – A Scientific Genius!

Eyewear has evolved over the years, whether as a sight correction instrument, a digital wellbeing device or a fashion accessory. It has had its own breakthrough moments, through various inventions and discoveries. The varifocal lenses are just one of those breakthroughs.

Although initially, the reach was limited but with the proliferation of e-commerce, there is now you can find an extensive range of varifocals online.

What Are Varifocal Glasses?

Also referred to as progressive lenses, varifocals are one of the finest creations of science. These glasses provide a clarity of vision for all distances. And this is made possible by using just a single lens. Varifocals are a modification of the bifocal lenses.

Varifocals glasses consist of three different visibility zones, for three different ranges of vision, i.e., distance, intermediate and far. What really makes these stand out is the divisions which are not visible to the naked eyes, hence not compromising on the physical appearance.

How Varifocals Work?

The main feature that guides varifocals functioning is the presence of multiple focal points on these lenses. The different sections of the lenses are optimised for various distances.

It is designed in such a way that the user gets the benefit of sight correction for both near and distance objects. The good news is that there are no manual adjustments required. You just put them on and leave it to the amazing varifocals to get along with its act.

Who Needs Varifocals?

Varifocals were specifically designed for those suffering from the defect of both nearsightedness and farsightedness. In contemporary times, such a condition is mainly prevalent in people above 40 years of age.

There is a general tendency for our eyesight – with respect to near objects – to weaken with age. When a threshold is crossed, a condition known as presbyopia may occur. When presbyopia sets in, one’s ability to see nearby objects (clearly) diminishes. A common problem one might encounter is an inability to read books and newspapers.

It needs to be noted that even those below 40 years of age may require varifocals, but there are rare occurrences for the same.

How Are Varifocals Different From Bifocals?

The major difference between these two variants lie in the number of focal points that they carry. While the varifocals have multiple focal points, bifocals – as the name suggests – consist of two focal points. This results in a smoother transition when we shift our gaze from an object far away to the one that is relatively close and vice-versa. The transition in bifocals may not be as smooth and can also get unpleasant.

In varifocals, the boundary separating the different zones are not visible, whereas there is a clear division when it comes to bifocals.

Are Varifocals Expensive?

Before we discuss the price of varifocals, it needs to be noted that varifocals serve the purpose of two glasses simultaneously, one for the purpose of reading and another for nearsightedness. So, it is natural for the prices to be relatively towards the higher end of the spectrum.

If you are looking for cheap varifocal glasses, you are just a few clicks away. All you need to do is head online. You will not only find affordable pairs but also a plethora of styles.

Buy glasses online and you will be surprised by both the savings that you make and the hassle-free experience that the online medium offers.
