There is a ‘distinct line’ of difference between the ‘visible line’ of bifocals and varifocal eyeglasses. When it comes to the difference and ease of usage between both the glasses, people have different stories to tell. Although, someone who has used bifocals throughout his life till the grey years will not be interested in varifocals. This is out to the sheer habit and long term association with the same glasses that the user does not want to forgo. Same is the story with the varifocal glasses. People who are getting used to varifocal glasses will not be favourable of going back to the old school bifocal glasses.
Let’s find out about Bifocal glasses and Varifocal eyeglasses?
Bifocal glasses have two prescription powers in one single lens, that is, it can correct both nearsightedness and farsightedness. The upper part of the lens helps in focusing on distance vision while the lower part of the frame, separated by a visibly distinct line, helps in correcting the close by vision errors.
On the other hand, the varifocal eyeglasses have not just two but three different degrees of focal points in a single lens. The upper and lower portion of varifocal glasses works similar to bifocal glasses. The major two differences among them are:
- Varifocal eyeglasses do not have any visible distinct line
- Varifocals have intermediate vision correction zone in between the upper and the lower portion, which helps in providing clear vision at a distance further than the arm’s length. This portion helps in viewing computers, laptops etc.
- Smooth transition from one zone of the lens to the other vision correction zone
What makes varifocals better than bifocals?
When using bifocals, the user has to shift not only the eyes; it requires movement of the neck as well. This can be understood with an illustration, to say you are reading a newspaper, then your head must have been tilted downward while bifocals are on. Since you are using the lower portion of the lenses to read. Now, suppose, you have to view any object that is placed at a far distance or maybe you want to watch out from the window. Here comes the catch. Now to view at a far off distance, if you will move only your eyes, you will view everything blurry. Why? Because the glasses are tilted downward due to the position of the neck that is to say your head is in a downward pose. Therefore, to view at a distance, you need to move your head upward, so that the glasses also move up and you can view a clear picture.
Now consider the case of varifocals, here if you are reading news in the newspaper and want to view at a distance object, you need not change the position of your neck. While sitting straight, you need to only move your eyes to read newspaper kept on the table and to view at an object kept far off, simply move your eyes. What is better with the varifocal glasses is that offer better vision along with covering a wide range of distance without the presence of any line. The best part of varifocal glasses is that while switching from one part of the lens to the other, it becomes easy to focus due to the absence of line as well as the smooth transition. The smooth unobstructed movement makes it easy for the user to view from distance mode to closer mode and vice versa.
While offering the wider field vision than the bifocals, the varifocal glasses minimises the possibility of distortion of the vision. Thus, they are easy to adapt to comparatively. You can say that bifocals are old technology lenses, whereas the varifocals are digitally advanced lenses that allow a seamless transition between the three parts of the lenses. Moreover, varifocals are the first choice among sportsperson, drivers, students, professionals, celebrities. For the reason that the smooth lens does not affect their looks, instead makes them appear more stylish, which is not the case with bifocals. Driving can become a dangerous business with the bifocals, whereas varifocals make it easy.
All said and done, the varifocals are easier than the bifocals in all aspects.

This is because your eyes and brain have become programmed to the glasses you were wearing previously.
However, slowly and gradually as your eyes and brains will be getting used to varifocal glasses, these symptoms will vanish. Generally, people get accustomed to new glasses within 15 to 20 days period.
