Practical Home Safety Tips for Vision Changes in Dementia
If your loved one with dementia has started bumping into furniture, missing steps, or seeming confused in familiar spaces, vision changes may be part of the picture.
Dementia doesn’t just affect memory. It can also change how the brain processes what the eyes see. Your loved one’s eyesight might test fine at the optometrist, but they may still struggle to judge distances, notice obstacles, or make sense of busy visual patterns.
These changes can lead to falls, anxiety, and frustration for both of you. The good news is that many home adjustments are simple, inexpensive, and can make a real difference in safety and comfort.
This article walks you through practical changes you can make room by room, along with tips for lighting, contrast, and reducing visual clutter. You don’t need to renovate your home. Small shifts can help your loved one move more safely and feel more at ease.
Understanding Vision Changes in Dementia
Before jumping into solutions, it helps to understand what might be happening.
In many types of dementia, especially Alzheimer’s disease, the brain has difficulty interpreting visual information. This is different from typical age-related vision problems like cataracts or macular degeneration, though those can occur at the same time.
Common vision-related challenges in dementia include:
- Depth perception problems. Your loved one may misjudge the height of a step or the distance to a chair, leading to falls or hesitation.
- Difficulty with contrast. They may not see a white toilet against a white floor, or a clear glass on a light countertop.
- Sensitivity to glare. Bright lights or shiny surfaces can cause confusion or discomfort.
- Trouble with busy patterns. Patterned rugs, floors, or wallpaper can look like obstacles or holes, causing fear or hesitation.
- Reduced peripheral vision. They may not notice objects or people approaching from the side.
These changes can make a familiar home suddenly feel disorienting. But with a few thoughtful adjustments, you can help your loved one navigate more confidently.
Lighting: Bright, Even, and Glare-Free
Good lighting is one of the most important and overlooked safety tools.
Increase overall brightness. Older eyes need more light to see clearly. Aim for bright, even lighting throughout the home, especially in hallways, stairs, and bathrooms. Consider higher-wattage bulbs or adding extra lamps in dim areas.
Eliminate harsh shadows. Shadows can look like holes or obstacles. Use multiple light sources in a room rather than one overhead light. Floor lamps or under-cabinet lighting can help fill in dark spots.
Reduce glare. Shiny floors, glass tabletops, and mirrors can create confusing reflections. Use matte finishes where possible, add non-glare coatings to picture frames, and consider sheer curtains to soften bright window light.
Use nightlights strategically. Place nightlights in hallways, bathrooms, and between the bedroom and bathroom. Using motion-sensor lights can be particularly beneficial for navigating at night.
Keep lighting consistent. Moving from a bright room to a dark one (or vice versa) can be disorienting. Try to maintain similar light levels throughout the home.
Contrast: Making Objects and Edges Visible
When depth perception is impaired, contrast becomes essential for safety.
Use contrasting colors for key items. A dark toilet seat on a white toilet, a brightly colored handrail against a neutral wall, or a red placemat under a white plate can help your loved one see important objects clearly.
Mark edges and transitions. Add a variety of colored tape on the edges of steps, thresholds, and countertops. This helps the brain recognize where one surface ends and another begins.
Choose solid colors over patterns. Busy patterns on floors, rugs, or bedspreads can look like obstacles or movement. Solid, contrasting colors are easier to interpret.
Make doors and doorways visible. If doors blend into walls, consider painting the door frame a contrasting color. This helps your loved one identify where to walk.
Avoid clear glass. Clear glass tables, shower doors, or cabinet fronts can be invisible and dangerous. Use decals, frosted glass, or solid alternatives.
Reducing Clutter and Visual Confusion
A simpler visual environment is easier for the brain to process.
Remove unnecessary furniture and decor. The less there is to navigate around, the safer the space. Keep pathways wide and clear.
Secure or remove loose rugs. Rugs with patterns can look like holes or steps. If you keep rugs, choose solid colors and secure them with non-slip backing or tape.
Minimize reflective surfaces. Mirrors can cause confusion, as your loved one may not recognize their reflection or may think another person is in the room. Consider covering or removing mirrors that cause distress.
Organize items simply. In kitchens and bathrooms, keep frequently used items visible and in consistent places. Too many choices or hidden items can increase frustration.
Close closet and cabinet doors. Open doors and cluttered shelves can be visually overwhelming.
Room-by-Room Safety Checks
Here are quick tips for the most important areas of the home:
Bathroom
- Install grab bars near the toilet and in the shower or tub.
- Use a contrasting toilet seat and bath mat.
- Remove glass shower doors if possible, or add decals.
- Keep lighting bright and even.
Bedroom
- Ensure a clear path from bed to bathroom.
- Use nightlights or motion-sensor lights.
- Choose solid-colored bedding to help your loved one see the bed clearly.
Stairs
- Mark the edges of each step with contrasting tape.
- Ensure handrails are sturdy and easy to see.
- Keep stairs well-lit, with light switches at both top and bottom.
Kitchen
- Use contrasting placemats and dishes.
- Store frequently used items at eye level.
- Remove or secure rugs in front of the sink or stove.
Living areas
- Arrange furniture to create clear walking paths.
- Remove low coffee tables or footstools that are easy to trip over.
- Keep cords tucked away and out of walking paths.
When to Talk with the Healthcare Team
If you notice unexpected changes in your loved one’s vision or an increase in falls, it’s important to speak with their healthcare provider. Some vision problems, like cataracts or glaucoma, can be treated. Others may indicate a change in the dementia itself.
An occupational therapist can also do a home safety assessment and recommend specific modifications for your situation. Ask the care team for a referral if you’d like personalized guidance.
Key Takeaways
- Vision changes in dementia are common and can affect depth perception, contrast sensitivity, and the ability to interpret busy patterns.
- Bright, even, glare-free lighting is one of the most important safety tools in your home.
- Use contrasting colors to make edges, objects, and doorways easier to see.
- Reduce clutter, remove tripping hazards, and simplify the visual environment.
- Talk with the healthcare team if you notice sudden vision changes or an increase in falls.
You don’t need to make every change at once. Start with the areas where your loved one spends the most time, and adjust as you go. Every small improvement helps.
