Sometimes there are visual acuity guidelines for various activities like driving.  However, there are no such guidelines that suggest that a certain level of visual impairment is necessary before a patient should seek low vision rehabilitation.  

Nevertheless, it is critically important that patients not be pre-selected for a referral to a low vision doctor. Some professionals believe that a patient is too old to benefit from low vision rehabilitation.  That attitude fails to show respect for the patient’s own values and desire for his or her own quality of life.  

At patient should be referred for low vision rehabilitation on the basis of the patient’s own complaints about their vision and if those complaints cannot be resolved with conventional eyeglasses, contact lenses or medical treatments.  The patient can then decide for his or her self whether the available rehabilitation approaches are suitable for and meet the patient’s needs.
