Periphery Revisited

Peripheral vision is so important. What's it worth to a person who rides a bicycle to notice objects (or cars) in the periphery? What's interesting is that the better your observance of periphery, the better balance you have. Peripheral vision is so important in many professions. One that comes to mind is law enforcement. What's interesting is that when some of us are in stressful situations, our periphery tunnels down.

Sometimes through vision training, we could improve one's periphery.

The above situations are what I call functional. In other words when these patients are given a peripheral vision test within the office, their findings are normal. Of course, we have to rule out peripheral vision defects due to pathology in the eye or the brain. These are permanent and don't respond to training.
