What is the difference between a 6/6, 6/9, etc., eye vision?
Oh, I see. Is there a difference in treatment for different measurements?
Different treatments depend on the cause of the vision problem. For example, if someone has 6/60 vision or worse, they may use a white cane or a guide dog. In contrast, if someone has 6/9 vision, they may simply need glasses to correct their vision.
