The NOHL only affects the vision, and does not affect the happiness. In any case we can be congratulations regardless of how much we affect this pathology, to our vision. We can make some experts "not see".
Carl Jung said "He who looks outside, dreams. Who looks inside, awakes".
The LOHN may be the opportunity to discover new things and another way of looking at life. There is No worse blind as those who will not see. So many times the fact of not seeing, not prevent you from seeing many other things.
A rapid diagnosis and an early attention to the patient to facilitate the adaptation of this to its pathology, and its new way of seeing life.
