Did you know that before varifocal glasses were invented, people had to rely on different pairs of glasses to see things at different distances? Switching between glasses while driving, reading or watching TV isn’t convenient and can be frustrating.
Varifocal glasses provide a seamless transition between near, intermediate and distant vision zones. This implies that you can see clearly at any distance without carrying different pairs of glasses and having to switch between them.
How do varifocal glasses work?
Varifocal lenses feature three vision zones, including:
Near
: This vision zone is located at the bottom of the glasses and allows the wearer to see clearly at near distances. For example, while reading a book or using a phone.
Intermediate
: This vision zone is located in the middle of the glasses and allows the wearer to see things at arm’s length, for instance, while working on digital screens.
Distance
: This vision zone is situated at the top of the varifocal glasses and offers a clear view when looking at far away objects, such as while watching movies on TV screens or looking at the traffic light from your vehicle.
Varifocals vs bifocals
Bifocal lenses offer near and distance vision correction with a visible line separating both zones. Varifocal lenses, on the other hand, do not have visible lines separating near, intermediate and distance zones, offering a seamless transition.
Top reasons why varifocals are a smart choice
Varifocals offer optical advantages and are also a smart choice for people. Here’re the reasons why:
Customisable, convenient and comfortable
Varifocals are not ‘one size fits all’ solutions. Instead, they are customised depending on your prescription. Your optician will take measurements, including your pupillary distance (the distance between the centre of your pupils), fitting height (the measurement taken from the bottom of your glasses to the centre of your pupil) and frame position (how the lens sits on your face and aligns with your eyes). These measurements ensure the lens suits your needs, fits your chosen frame and matches your routine. Also, since these lenses include all three vision zones, you don’t need to switch between multiple pairs of spectacles, meaning you get convenience and comfort in a single lens.
Suitable for presbyopia
Varifocal lenses are suitable for presbyopia, a condition that primarily affects individuals over 40. People affected by this condition often find it challenging to focus on objects at a near distance, such as when checking a notification on their mobile phone or skimming down a menu.
Shorter period to get used to
Though varifocals provide a smooth transition, it might take about 2 to 3 days for first time wearers to get used to these lenses. Some people might feel a bit uncomfortable at first, however, the experience and adjustment period will vary from person to person.
How to know if you need varifocal lenses
If you have multiple prescriptions, one for reading, one for working on computers and another for seeing far away objects, you certainly need varifocals. Always consult your optician first before going for varifocal glasses.
Where to shop varifocals from
You can find varifocals at your local opticians or reputed online retailers like Feel Good Contacts. These glasses offer long-term benefits combining comfort, clarity and convenience altogether, making them a smart choice.
