Final answer:
The potential acuity pinhole technique is a method used to assess visual acuity by using a pinhole to improve focus. It helps determine the closest object a person can see clearly.
Step-by-step explanation:
The potential acuity pinhole technique is a method used to assess a person's visual acuity. It involves using a pinhole to improve the focus of light entering the eye, which can help determine the closest object a person can see clearly. The pinhole restricts the light coming into the eye and reduces the effects of refractive errors, allowing for a clearer image to be formed on the retina.
