Choosing Between Bifocal & Varifocal Glasses?
Having separate pairs of glasses can be a nuisance. Bifocal and varifocal lenses allow you to have only one pair of glasses, even if you need varying types of lenses for your vision.
For the majority of people, they are the most convenient way to resolve the problem of needing different corrections for long distance, intermediate, and near.
It’s important that you find the lens that will work best for you, and this will depend on your own individual preferences and prescription.
Read on to explore more about bifocal and varifocal glasses, so you can decide which lens best suit your requirements.
Bifocal Glasses
Bifocal lenses are most commonly prescribed to wearers with the age-related condition presbyopia. This results in people requiring glasses with two different prescriptions, one for short and one for long distance.
On bifocals, these two prescriptions have a distinct line between them. Wearers have to look up and down to switch between the prescriptions they need, with the long-distance prescription at the top and near vision at the bottom.
Benefits of Bifocals:
- Convenient
- Cheaper than varifocals
- Initially easier to get used too
Varifocal Glasses
Varifocal (or multifocal) lenses cater to multiple prescriptions. Unlike bifocal glasses, varifocal glasses change prescription seamlessly throughout the lens.
There is no definitive line. The lenses progressively change power in a gradual transition from distance into up-close viewing, as you move your eyes from the top to the bottom of the lens. It allows for middle distance and quick changes of focus as the wearer needs it.
Benefits of Varifocals:
- Can accommodate more prescriptions of lenses
- More aesthetically pleasing as there’s no line in the lens
- Can see at all distances
