To learn properly we need 3 kinds of qualities:
Enough intelligence level;
Background knowledge to understand and;
PERCEPTION ABILITY
The proprioceptive dysfunction leads to perception disability.
If a person has enough intelligence level and enough knowledge to understand but he can't learn properly, we must take action in order to find out the proprioceptive dysfunction.
If this is the case, this is the only way to properly help this person.
When a patient goes to an optician and asks if he/she is able to prepare glasses with active prisms, the answer is usually YES.
If, instead, the optician was asked if he/she had ever received a specific training for preparing glasses containing active prisms, the answer would usually be NO.
Many opticians declare that preparing active prisms is the same as preparing other types of prisms, that there are not major difficulties added or special knowledge needed... They say.
Please note this:
Preparing active prisms needs a specific knowledge to ensure good results. It is not enough to put the prisms in the frame.
Please see The Optician and Active Prisms for a better understanding.
