II. Progressive Lens:
- What are progressive lenses?
These are multifocal lenses that correct vision at different working distances, from reading distance to far distance.
Unlike bifocals, they have a gradual change in prescription and don't have visible lines that separate the segments, so they look just the same as single vision lenses.
The distance vision part of the lens is usually in front of the pupil, with the near vision part in the lower section of the lenses.
If you've been wearing single vision lenses, it might take some time to adjust to wearing them.
 | Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision. - Natural, clear and balanced vision from far to near
- Low astigmatism provides visual comfort and easy adaptation
- Larger far zone and comfortable reading zone

- Benefits of Progressive Lenses
---With progressive lenses, you won't need to have more than one pair of glasses with you. You don't need to swap between your reading and regular glasses.
---Vision with progressives can seem natural. If you switch from viewing something up close to something far away, you won't get a "jump" like you would with bifocals or trifocals. So if you're driving, you can look at your dashboard, at the road, or at a sign in the distance with a smooth transition.
---They look like regular glasses. In one study, people who wore traditional bifocals were given progressive lenses to try. The study's author said most made the switch for good.
