Advantages
and Applicable Objects of Progressive Lens
There are multiple focal points on progressive
lens. This lens is not an automatic zoom lens, there is a progressive zone
which is between the fixed far vision zone above the lens and the near vision
zone below the lens. In this zone, the refractive power of the lens is gradually
increased by decreasing the radius of curvature of the lens. It’s not suitable
for all the people.
Advantages:
1. Uninterrupted vision from far to near, clear at far, middle and near distances
