Varifocals and bifocals are always a common topic to fuss about when you are in your 40’s. It’s understandable why many people are hesitant among these lenses. Bifocals have been available for quite a while now while varifocals are new to the market. Many of us hate to take risks or try something new however good it may be but here staying with bifocals can be a disadvantageous move. Not only, bifocals are an old mode of lens type but it’s also lacking in giving solutions with other vision-related problems. Read on to find out how varifocals are better than bifocals.
What are Bifocal glasses?
Bifocal glasses are types of glasses that are used by people who suffer from presbyopia or myopia. Bifocal glasses contain two different types of lenses incorporated in a single lens. The whole portion of bifocal lenses are divided into two parts, the upper part of the lens offers distant vision and the lower portion offers near vision.
Bifocal glasses can correct your far vision when you’re in the upper portion of the lens and if you want to read a book then you can look from the lower part of the lens. Bifocal glasses contain a visible division line which separates both lenses. It does look good as people can know your age by looking at your glasses. Bifocal lenses only contain two vision corrections as there is no section in the lens to help with computer work.
What are Varifocal Glasses?
Varifocal glasses are glasses with three different vision corrections embedded in a single lens. Varifocal glasses are also used by presbyopic and myopic vision i.e people whose near distance vision is weak and find it hard to read books or identity near objects. The topmost part of the lens offers distance vision correction, the intermediate portion helps with computer work like reading a website on the web or doing any sort of computer work. The lower section of the lenses allows you with near distance correction.
Varifocal glasses don’t have any visible division line that separates the three different lenses and it looks aesthetically beautiful and clear. Varifocal glasses don’t tell of your age and it’s a modern replacement of bifocal glasses. It not only got rid of the divisible line but has also given a different section in the lens to allow computer work.
Which lens offers a better transition from near to far and vice versa?
Varifocal glasses have better transition compared to bifocals as it doesn’t contain any divisible line hence there is a smooth gradual shift from far to internet and near. You just have to move your pupils rather than shaking your head or adjusting your glasses a bit too much to get the right type of vision. Varifocal glasses also contain peripheral distortion in the lens sides which are blurred so that your pupil gets the seamless transition from near to far without any distraction. Bifocal glasses, on the other hand, don’t contain any peripheral distortion and there is no smooth transition in the lenses. You have to look in the section whenever you need to and can’t get the seamless travel of far and near.
Hope you got the answer you were looking for. Don’t you want a seamless shift of vision rather than just looking into different lenses for reading a book or looking for something in the sky?
