Vol.6 Story about medium and near lenses
With the spread of telework and remote work, the number of information on "middle-near bifocal lenses" that are specialized for indoor use is increasing.
I think that there are many people who are not familiar with the bifocal lens itself, so I will introduce the difference between the bifocal lens and the bifocal lens and the situation of proper use.
1. What is a near-near lens?
The big difference between bifocal lenses and bifocal lenses is the range of viewing distance.
Bifocal lenses are characterized by having many parts that are in focus at long distances, and there are few parts that are in focus at medium and short distances.
It is a lens that can cover from far to near, such as driving a car to your smartphone, with a single pair of glasses.
On the other hand, the bifocal lens is designed so that the part of the upper part of the lens that is in focus is narrowed and the part that is in focus at medium and short distances is wide.
Mainly from medium distance (2m to 3m) to short distance (about 30cm to 40cm), it is difficult to see at long distance (beyond 5m), but the field of view at hand is wider than bifocal lens. , It is a lens that does not easily cause shaking and distortion peculiar to progressive lenses.
