If I know the answer to that I may also know the answers to the following : Why do people with perfect eyesight run into doors without seeing it? Or professional drivers have accident? Answering a why question is hard or would require a fair amount of involving other things. This is still a work in progress. Thanks

Let me see if i can be of help here, you will agree with me that most times people dont take good care of their eyes maybe because of the high cost of living in Nigeria or else where. The eyes has all that magnetic abilities but people tends to miss their way or run into objects when their eyes does work or interact with the right senses in their body. Just my thoughts and like you said " work in progress" @greenrun
