Why do I need multifocal lenses?

These common lenses enable you to see objects that are far away, objects that are at an arm’s length distance (like working on a computer), and objects that are close-up like when reading.
How do I know if I have farsighted or nearsighted glasses?
The more nearsighted (or farsighted) you are, the higher your prescription in diopters. Refractive Power – The first number in the series identifies your degree of nearsightedness or farsightedness. A plus sign (+) indicates you are farsighted, a minus sign (-) indicates you are nearsighted.
What is the difference between multifocal and progressive lenses?
The difference between progressives and multi/bifocal glasses is that progressive lenses lack the telltale lines on the lenses that separate each visual zone. Progressive lenses provide a much more seamless transition between near and distant vision.
How do you tell if your progressive lenses are correct?

Presbyopia usually becomes noticeable in your mid-forties, and at first is often only a problem when reading.

What are the most widely used distance glasses?
Single vision lenses – the most widely used distance glasses Single vision lenses are eyeglass lenses that only have one dioptric power throughout the entire lens.
How do distance eyeglasses work?
As their name implies, distance eyeglasses enable wearers to see distant objects more clearly. People generally start using them before they reach the age of 40. After this point the eye’s ability to change its focus from one distance to another, known as the amplitude of accommodation, is no longer sufficient to see clearly at all distances.
