Vol.7 Story about near and near lenses
Following on from the bifocal lenses introduced in Vol.6 "Talking about medium-near lenses", we will introduce "near-near lenses" that are more specialized for desk work, and situations for proper use.
1. What is a near-near lens?
Normally, for near-field glasses, the power is set according to the easy-to-see distance of about 40 cm (it moves back and forth depending on the physique and posture), but distances beyond that are blurred and invisible.
For example, when you want to watch TV while reading a newspaper, you have to take off your near-vision glasses to watch TV.
The near-near lens is a lens that allows you to see around 40 cm at the bottom of the lens and about 1 m from the center to the top of the lens. The feature is that it is hard to feel distortion.
It is inconvenient that you cannot stand up or walk because your feet are blurred while wearing these glasses, but it is a lens that is very useful for long hours of desk work and computer work.
In addition, many people are using the near-near lens with the effect of blue light cut.
