In the context of optics or Photography, "non-focal" typically refers to objects or elements that are not the primary focus of the lens. This can include background elements or out-of-focus areas in an image. Non-focal points do not fall within the plane of focus determined by the lens and may appear blurry or less defined compared to the focal point.
The term "non-focal," when related to a neurological examination of a patient, typically means the patient is experiencing light-headedness, faintness, dizziness, generalized weakness, maybe some blackouts, with altered or loss of consciousness, and confusion. Other symptoms may include ringing in the ears, difficulty swallowing, slurred speech, double vision, and/or loss of balance. Actually, I believe that this is wrong. It means the patient is moving all extremities in a normal fashion as well as walking and talking normally and there is no obvious sign of neuro impairment. This is often used when a detailed neuro exam is not felt to be clinically necessary; there is no suspicion of a neurological problem, so a detailed neuro exam is not performed.
