Progressives provide a more natural correction of presbyopia than bifocals or trifocals. They are considered "multifocals" because there is a seamless progression from distance to near with an intermediate section in between. This provides many focal points in order to satisfy almost any visual need.
With progressives you can look up to see clearly across the room or down the street while driving. You can also look ahead to see your computer or someone sitting across the dinner table through the intermediate section. If you drop your gaze downward, you can read fine print comfortably through the bottom of the lens.
There is a corridor that runs vertically down the middle of the lens and measurements will be taken to fit the corridor in the right place so all powers can be accessed comfortably.
Progressives also eliminate a problem called "image jump" which is experienced with bifocal and trifocal lenses. The lines on the lenses create a drastic change in power which causes images to appear to jump as you move from distance to near. Progressives create a smooth, more comfortable transition from distance to near and back.
Progressive lenses are far more sophisticated and technologically advanced than their common name (often called “no-line bifocals”). The newest, best version of these lenses provides the closest thing to natural youthful vision that a presbyopic person can achieve. Progressive lenses provide an uninterrupted view of the world with a gradual focus change from far to near and everything in between without the traditional bifocal line that so many perceive as ugly and a sure sign of aging. The best brand of progressive lenses is far superior to conventional bifocals or trifocals in virtually every comparison except price. Yes, progressive lenses are technologically superior to bifocals and do cost more. Many optometrists and opticians also recommend that when you purchase progressive lenses you should buy the best the optical store has to offer. We recommend MyFocal HD Progressive lenses (sold exclusively at Visionworks) or one of the best Varilux brands. Vision distortions, narrow viewing areas and the inability to adjust to your progressive lenses are much more common with inferior quality brands of progressive lenses.
