Is dopamine good for eyes?

Dopamine (DA) is an important neurotransmitter in the retina and mediates diverse functions including development, visual signaling, and refractive development.

Can low dopamine cause eye problems?

Lack of dopamine can therefore lead to a range of visual disturbances in PD patients, such as diplopia. PD patients also have an increased risk of eyelid apraxia and blepharospasm or dry eyes.

Can dopamine cause blurry vision?

Blurry vision may be related to dopamine depletion in the back of the eye and within the visual connections through the brain. This may be partially corrected with dopaminergic medications, though medication effects are usually subtle regarding vision, so you may not notice them.
