Confusion sometimes occurs when you try to buy lenses online and want to find the right type of lenses for your particular sight needs.

When buying varifocal or bifocal lenses, knowing what each one does and which is the best for you can save you time and money!

Bifocal and Varifocal lenses are corrective lenses used in glasses to correct ‘presbyopia’ – a reduced ability to focus on near objects, caused by natural ageing, which is usually noticed between the ages of 40-50 – and other similar disorders.

They are characterised by a gradual increase of lens power, usually between 15 and 20 mm with a final addition power between 1.00 to 2.50, which is added on to the wearers other sight corrections. The level starts at a minimum – or no additional power at the top of the lens – and reaches a maximum additional power of magnification, at the bottom of the lens.

What are varifocal Lenses?

Varifocal lenses allow you to see near intermediate and far using just one pair of glasses. unlike bifocals there’s no visible line, just a smooth transition from near to far

Benefits of Varifocal Lenses

· No visible lines

· Accurate blend of distance, intermediate and reading prescriptions.

· See clearly at all distances

· Look just like ordinary lenses

What are bifocal Lenses

Bifocal lenses are two prescriptions in one lens. You only need to use the one pair of glasses for reading, TV or driving

Benefits of bifocal lenses

· Combination lens for both distance and reading

· No need for two pairs of glasses

· Choice of D-segment or a C-segment

Applicable to both men’s glasses and women’s glasses, the lens is best suited for viewing distant objects at the top of the lenses and viewing nearby objects at the bottom of the lens.

By simply tilting your head the corrected sight view is obtained. Reading occurs usually low in the visual field and distant objects higher in the visual field, so only small movements of the head are required.
