The most important parts of vision are central, so perimetry should also capture the central parts well during the fitness to drive test. This video shows how it should be done.

shows intact central visual field up to 10°
Finger counting in the middle periphery

The rate of short-sightedness has increased and with it diseases such as glaucoma or retinal detachment. Can this be prevented? And if so, how? Below is a link to a pulse program and the current SOG guidelines. The short answer is: Yes, you can prevent progression, with special lenses, as well as with drops or combined, but environmental factors are most important, more important than genetics. Children should therefore spend at least 2 hours a day outdoors and take a break every 20 minutes when reading. What doesn't help, by the way, is eye training.
