No animal needs glasses.
It is very strange why man needs glasses.
The reasons are two:
the first is the physiological reason; and the second is the psychological.
The physiological reason is that our process of helping a mother
to give birth to a child is basically wrong.
For example, the child has been for nine months in deep darkness;
his eyes are very delicate, fragile.
And in any hospital where he is going to be born,
he is going to face, immediately after the birth, glaring lights all around.
That is the first shock to the whole delicate system of his eyes.
And eyes are the most delicate part of your body —
softer than a rose petal, very fragile and very important,
because eighty percent of your life's experience depends on them.
Only twenty percent is contributed by your other senses.
