Science has taken us places. It has made life simple and no longer just a survival game. Humanity has witnessed discoveries and inventions that one would not even have imagined in the wildest of their dreams. Nothing is impossible - might just be possible.
For those who have kept a track of the evolution of eyewear, will definitely rate varifocals among the top inventions that eyewear has seen. The varifocals is not just another invention, but goes far beyond this with its ability to transform the lives of those suffering with major vision disorder.
What Are Varifocal Lenses?
Varifocal lenses are an advanced version of lenses, deriving its advancement from the multiple focal points that it consists of.
It comprises three different visibility zones, that are segregated smartly for distance, intermediate and near vision. To your naked eyes, these zones are not visible but you can only experience it once you put on your glasses.
How Does It Work?
With the help of the three visibility zones and multiple focal points, varifocals allow one to get sight correction for both distance and near objects and anything that lies in between.
This is achieved without the need for any adjustment as the zones of these lenses are designed in such a way that it aligns with your requirement of looking clearly at objects placed at variable distances. All you need to do is to put them on and let the varifocals perform its magic.
Who Needs Varifocals?
Anyone who requires a sight correction for both near and far objects can benefit greatly with the shift to varifocal lenses. These lenses serve the purpose of both distance and reading glasses. This wipes off the need to carry two separate glasses for both these purposes,
Simultaneous occurrence of both nearsightedness and farsightedness is mainly observed in people who are above 40 years of age. With ageing, our eyesight with respect to near objects may get weaker. This condition is known as presbyopia, which is absolutely normal.
We already had bifocals for the same purpose. Why varifocals then?
How Are Varifocals Different From Bifocals?
As already discussed, varifocals have multiple focal points whereas bifocals come with only two focal points. Due to the multiple focal points of the varifocals, these lenses facilitate a smooth transition when one needs to change their line of vision between objects at varying distances. The same process in bifocals results in an abrupt transition, which may get irritating at times.
The boundary of different zones in the bifocal lenses is visible to the naked eyes. However, this is not the case when it comes to varifocals, giving it a better appearance.
What Are The Best Frames For Varifocals?
Frames become very crucial when we are talking about varifocals. The larger the size of the frame, the better it is. Large frames incorporate large lenses, which help in widening the field of view. This will make the transition from far objects to that of near ones or vice versa smoother.
However, opting for large frames is not a hard and fast rule and even relatively smaller frames will do.
Here, we have compiled a list of frames that will give your varifocal lenses the charm they deserve. These recommendations are applicable to the population above 40 years of age, considering that the defects to which these lenses cater are mainly observed in this population.
- Oversized Frames
In case of varifocals, oversized frames are not only a fashion statement but also one that suits well, keeping the rule of size as the benchmark.
Those who have categorised oversized glasses as a funky one - only to be used by youth - you need to see the ones with sleek metal frames. The sleek metal oversized frames are our first recommendation for your varifocal lenses.
- Round Frames
Utilise the retro round frames to make your varifocals the perfect vintage glasses. This is a perfect option for those with angular face shapes. The round shape also aids in making the transition between objects at varying distances.
- Browline Frames
Browline frames are a wonderful option for your varifocals, especially when the requirement is office use. The sophisticated design of the frame gives a professional touch to your physical appearance.
Varifocal lenses are a superior eyewear instrument. It might take you a week or two to adjust to these lenses, but once this initial phase passes, you will be ready to declare your varifocal glasses as your best friend.
