When you’re buying glasses online, confusion can sometimes occur when you want to find the right type of corrective lenses for your particular prescription.

When purchasing varifocal or bifocal glasses, being in possession of all the facts and knowing which option is the best for you can save you time and money.

What are Bifocal and Varifocal lenses?

Varifocal or bifocal lenses are corrective lenses used in glasses to correct a condition known as  ‘presbyopia’. This is a reduced ability to focus on near objects caused by ageing. The condition usually occurs in people over the age of 40-years of age.

Bifocal and varifocal lenses can be fitted to new and existing frames. This includes budget glasses and designer frames, such as Polo, Oakley and Ran Ban frames.

What Are Varifocal Lenses? 

Varifocal lenses allow you to see near and far using just one pair of prescription glasses. They also have an ‘in-between’ range which is handy for seeing objects in the middle distance.

The benefits of varifocal lenses are there no visible lines (like the ones found on a bifocal), an accurate blend of distance, middle and reading prescriptions, and an ability to see all distances clearly. What’s more, they look just like regular lenses.

What Are Bifocal Lenses? 

Bifocal lenses incorporate two prescriptions into one lens. You only need to use one pair of glasses for reading, watching television and driving.

Used in both men’s glasses and women’s glasses, the bifocal lens is best suited for viewing distant objects through the top of the lenses and nearby objects using the bottom of the lens.

Benefits of Bifocal Glasses

The benefits of bifocal lenses are they offer a combination lens for both distance and reading, there’s no need for two pairs of glasses and you have a choice of D-segment or full-width divide.
