People living with Parkinson’s often have trouble with their eyes
Parkinson's disease can short-circuit nerve signals between your eyes and your brain. It can so impair the muscles and nerves that control eye movement.
I have dry eyes/without tears that caused my eye tired and sensitivity to light when I am driving or reading.
To alleviate eye problems I use more light when you read besides I use tears eye drop daily
Dry eyes are caused by a lack of tears. Tears are necessary for the normal lubrication of your eyes and to wash away particles and foreign bodies
It's hard to distinguish between Parkinson's disease-related eye problems and natural, age-related changes in vision.
