Parkinson’s gradually damages the brain. Over time, symptoms will begin to appear. When the vision is affected, what happens?
The charity, Parkinson’s UK, states people with the condition will often experience problems with their eyesight.
For instance, difficulty can arise when starting to move the eyes, or when trying to move them quickly.
This may be more apparent when trying to look at fast-moving objects, such as cars.
Another symptom is tracking – this involves the eyes having trouble moving smoothly across a line or from one object to another.
Additionally, people with Parkinson’s may blink less often, which can result in dry and sore eyes.
And eyelid apraxia can occur when the muscles that open the eyelids aren’t working properly.
This could lead to the eyelids closing involuntarily and most often happens during speech.
Moreover, people with Parkinson’s can find it hard to see in low light.
This includes being unable to clearly make out the shapes of light-coloured objects on a light background.
And sufferers may even experience hardship telling the difference between colours.
Specifically, this may be worse for shades of blue, green or both.
