Progressive lenses
Progressive lenses change power gradually from distance at the top to reading at the bottom, with no visible line. They let you see far, at arm's length and up close through one pair, once the fit and your habits are right.
How the zones work
The upper part of the lens holds your distance power. A narrow corridor below it adds power step by step for screens and dashboards, and the lower part holds your full reading power. The sides of the lens are softer by design, so you turn your head rather than your eyes to look sideways.
Fit matters more than with single vision
The corridor must line up with your pupils. That needs your PD for each eye and a fitting height measured with the chosen frame on your face. Choose a frame with enough lens height to fit all three zones; very shallow frames are not suitable for progressive lenses, and those frames say so on the product page.
The first weeks
- Wear the new pair for full days rather than switching back and forth.
- Point your nose at what you want to see, then move your eyes down to read.
- Take stairs carefully at first and look through the top of the lens.
If something still feels wrong after two weeks, ask your eye care professional to check the prescription and fit.

Progressive lens questions
What is the difference between progressive and bifocal lenses?
A bifocal has two powers split by a visible line. A progressive changes power smoothly and adds the intermediate range in between, with no line.
Do I need a fitting height?
Yes. It places the corridor at the right level for your eyes in the frame you chose. It is measured with the frame adjusted on your face.
Can I wear progressives at a computer?
Yes, through the intermediate corridor. If you work at a screen all day, a dedicated pair for that distance can be more comfortable.
