Bifocal & Varifocal Lens Comparison:
Bifocal and Varifocal lenses are corrective lenses used in spectacles 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 levels 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.
