How Does Parkinson’s Disease Affect Vision in Sacramento, CA

When people think about Parkinson’s, they typically focus on the loss of motor skills. However, the disease can also impact vision and make it difficult to complete various tasks that don’t involve motor function or mental health. Continue reading to learn how Parkinson’s disease can affect a senior’s vision and what family caregivers can do to help with each issue.

Blurred Vision

As Parkinson’s progresses, it could impact your aging loved one’s eyesight. The disease can change how the eyes move, and your loved one’s sight may become less sharp. You may also notice your loved one straining his or her eyes to focus on an object or person. The blurred vision could exacerbate coordination and balance problems, increasing the risk of slips, falls, sprains, and other serious accidents. Help your parent navigate the home, and look for ways to make daily life and activities more manageable.

Seniors with severe vision impairment may need assistance to be able to continue living at home. For many seniors in Sacramento, California, live-in care is an essential component of aging in place safely and comfortably. However, it’s important for them to have caregivers they can trust and rely on. At Home Care Assistance, we extensively screen all of our live-in and 24-hour caregivers and only hire those who have experience in the senior home care industry. Our strict requirements ensure seniors can remain in the comfort of home with a reduced risk of injury or serious illness.

Blinking Abnormalities

Blinking reflexes can decrease substantially with Parkinson’s. The disease affects the ability to open and close the eyes voluntarily. Some doctors prescribe injections around the eyes to address blinking abnormalities. Keep in mind this issue can lead to dry eyes as well as eyelid irritation. When these health problems aren’t managed, your parent could develop an external eye disease. One of the best ways to prevent dry eyes due to blinking abnormalities is to use ointments that increase comfort levels and vision. Your loved one should also use lid scrubs and warm compresses to reduce irritation in the eyes.

Sensory Deficits

The neuron production in the eyes is typically reduced due to Parkinson’s. A loss of these neurons can make it difficult to differentiate between objects that are similar in color intensity. Colors in the blue and yellow spectrums are often challenging for seniors with Parkinson’s to distinguish. Doctors generally prescribe medication to help with dopamine loss, but your loved one may need to wear glasses to address vision deficits. Specific tints can make it easier to see contrast between colors when wearing glasses.

If your loved one is living with vision loss and needs assistance with daily tasks, help is available. Seniors can face a variety of challenges as they age, many of which can be mitigated with the help of professional in-home caregivers who provide high-quality senior care. Trust Home Care Assistance to help your elderly loved one age in place safely and comfortably.


One of the most common non-motor symptoms of Parkinson’s is hallucinations, and they cause seniors to see things that others don’t. For instance, your loved one may see a cat in the room that isn’t there or believe he or she sees a deceased friend. The hallucinations are often due to the loss of brain chemicals and receptors such as dopamine and serotonin. When the body doesn’t produce enough of these chemicals, it could lead to visual dysfunction and increase the odds of hallucinations and delusions. To address these issues, the doctor may simplify your loved one’s Parkinson’s medication regime or add other drugs. 

There are a variety of age-related health conditions that can make it more challenging for seniors to live independently. However, many of the challenges they face can be easier to manage if their families opt for professional at-home care. Sacramento families can rely on expertly trained caregivers to keep their loved ones safe and comfortable while aging in place.
