Progressive Lenses ( Helpful:3 ) Back »

Progressive or varifocal provide a smooth transition from distance correction to nearcorrection, eliminating segment lines and allowing the viewing of all inter mediate distances.

Thisprogressive lens has a typical configuration of distance, intermediate and nearzones.


Advantages of Progressive Lenses Over Bifocals and Trifocals


Progressive lenses also provide a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses.


Instead of providing just two or three lens powers like bifocals or trifocals,progressive lenses are true "multifocal" lenses that provide aseamless progression of many lens powers for all viewing distances.


With progressive lenses, you can look up to see clearly across the room and inthe distance. You can also look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably.


And it's easy to adapt to today's modern progressive lenses.


A "corridor" of optimum vision runs vertically down each progressivelens. Your eyecare practitioner will take careful measurements of your eyes and eyeglass frame in order to place the corridor in just the right location so your eyes can naturally access the various powers within the lens forcom for table viewing at all distances.


And progressive lenses eliminate an annoying problem caused by bifocal and trifocal lenses known as "image jump."


With conventional bifocals and trifocals, images seem to "jump" as your eyes move past the sharply defined boundary between the distance and nearparts of the lens. With progressive lenses, the transition between lens powerswithin the lens is smooth and seamless, letting you change focus from distance to near and back again more comfortably.
