Effects of Dementia on Vision in Pembroke Pines, FL

Dementia impacts the brain, causing seniors to experience visual changes and eye-related diseases such as macular degeneration and cataracts. Due to the vision and perception issues caused by dementia, seniors may have difficulty interpreting things related to their daily lives. Here are some of the ways dementia can affect an older adult’s vision.

Reduced Visual Perception

Dementia causes issues with visual perception because the condition affects the parts of the brain responsible for handling the visual information coming from the eyes. As the disease progresses, the mind will adjust by relying on one eye to see everything (as opposed to using both eyes), and blurred vision, decreased depth perception, and slower reactions to lighting may result. Things may also look bigger or smaller than they are. Going outside on bright, sunny days may also be difficult for older adults with dementia, which is why they should make a slow transition from dark and dim places to adequately lit and sunny areas.

Visual Misinterpretations

One of the common issues seniors with dementia experience is hallucinations. The sight problems caused by this neurological disorder could make seniors see things that aren’t there. For example, if a senior with dementia is sitting in the living room, he or she may see the reflection from the television and believe someone else is in the space. Although hallucinations can be stressful on seniors and their caregivers, the delusions aren’t permanent. Some of the ways to stop hallucinations in older adults living with dementia are to adjust the lighting in the home and avoid flooring and furniture with stripes and multicolored patterns. 

Vision impairment resulting from dementia may make it difficult for seniors to complete everyday tasks on their own. If your senior loved one has been diagnosed with a serious condition and needs help with tasks like meal prep, transportation, bathing, and grooming, reach out to Home Care Assistance, a leading provider of senior care Pembroke Pines, FL, families can trust. We also offer comprehensive care for seniors with dementia, Alzheimer’s, and Parkinson’s.

Decreased Visual Field

The areas of visual perception can become smaller due to dementia, impacting the way seniors see things. Aging adults with dementia may have difficulty recognizing nearby objects and people. For instance, closing the bedroom door may be difficult because dementia prevents them from finding the door, even though it’s in plain sight. Therefore, they’ll have to strain their eyes when doing basic tasks. Step in and help your senior loved one when his or her visual field becomes smaller because you can move around better and see things clearer.

Caring for a senior loved one can be challenging for families who don’t have expertise or professional training in home care, but this challenge doesn’t have to be faced alone. Family caregivers can turn to Pembroke Pines Home Care Assistance for the help they need. We provide high-quality live-in and respite care as well as comprehensive Alzheimer’s, dementia, stroke, and Parkinson’s care.


Although dementia can cause seniors to make visual mistakes and experience delusions, the condition doesn’t directly lead to permanent blindness. However, failing to receive treatment for issues such as glaucoma and retinal complications can increase the risk of permanent blindness in aging adults with dementia. If your loved one is diagnosed with dementia, take him or her to an eye doctor to determine what he or she can and cannot see. The doctor can recommend prescription drugs to treat eye-related conditions or schedule a surgical procedure. Living with dementia won’t prevent your parent from being able to receive vision surgery.
