Progressive lenses are a type of multifocal eyeglass lens designed to help people see clearly at different distances—far, intermediate, and near—without visible lines on the lens.
How Progressive Lenses Work
Your image shows the three main vision zones in a progressive lens:
*Distance Vision (Top Part)
The upper part of the lens is used for seeing far away.
Example uses: driving, watching TV, looking at scenery.
*Intermediate Vision (Middle Corridor)
The middle section is called the corridor.
It is used for mid-range distances.
Example uses: computer work, desk tasks, talking to someone across a table.
*Near Vision (Bottom Part)
The bottom part is designed for close-up tasks.
Example uses: reading books, checking your phone, sewing, reading menus.
Peripheral Distortion
On the left and right sides of the lens, there may be slight blurriness or distortion.
This is normal for progressive lenses because the power gradually changes from top to bottom.
Advantages of Progressive Lenses
✅ No visible line (more natural appearance)
✅ Smooth transition between different viewing distances
✅ Three vision zones in one lens
✅ Convenient – no need to switch glasses
Who Usually Needs Progressive Lenses?
Progressive lenses are commonly prescribed for people with presbyopia, which usually starts around age 40+, when the eyes have difficulty focusing on near objects.
Simple Summary
Progressive lenses allow you to see far, intermediate, and near in one pair of glasses with a smooth power transition and no visible lines.
