Slowed Blink Rate

It’s important to note that a reduced frequency of blinking is common with Parkinson’s. The normal blink rate is about 15 to 20 times per minute, but people with Parkinson’s may blink significantly less, sometimes only 3 to 4 times per minute. This reduced blink rate can lead to dry eyes, discomfort, and vision problems. Blinking helps spread tears across your eye’s surface, keeping it moist and clear. Managing this symptom involves using artificial tears and consciously blinking more frequently.
