September is Fall Prevention Month, making it a good time to think about some of the less obvious factors that can affect balance and everyday safety as we age.

Most people associate falls with things like muscle weakness, uneven sidewalks, loose rugs or slippery floors. But there’s another important piece of the puzzle that can sometimes be overlooked: your vision.

As we get older, it’s common to notice changes in eyesight. Reading small print may become more difficult. Driving at night can feel more challenging. Adjusting when you walk from a bright room into a darker one may take a little longer.

These changes can be frustrating, but vision also helps your brain understand where your body is in relation to the world around you. When visual information becomes less clear, safely navigating your surroundings can become more difficult.

Your Eyes Help You Stay Oriented

Balance isn’t controlled by just one part of the body.

Your brain constantly combines information from your eyes, inner ear, muscles and joints to help determine where you are, how you’re moving and what’s around you.

Vision provides important clues about your surroundings—where the floor begins and ends, how high a step is, whether an object is in your path and how far away something may be.

When visual information becomes harder to interpret, the body may have less information available to guide movement.

Vision Changes That May Affect Everyday Safety

Several types of age-related vision changes can make navigating your surroundings more challenging.

Reduced Contrast Sensitivity

Contrast sensitivity helps you distinguish an object from its background.

For example, a light-colored step against a similarly colored floor may be much harder to recognize when contrast sensitivity is reduced.

This can make curbs, stairs, rugs and changes in flooring easier to overlook.

Difficulty Seeing in Low Light

Many people notice that they need more light to see comfortably as they get older.

Dim hallways, poorly lit staircases and nighttime trips to the bathroom may become more difficult to navigate, especially when your eyes are still adjusting to a change in lighting.

Changes in Depth Perception

Depth perception helps you judge distances and understand how objects relate to one another in three-dimensional space.

It plays an important role when stepping off a curb, walking down stairs or reaching for something.

Reduced Peripheral Vision

Peripheral vision helps you notice things that aren't directly in front of you.

Changes in peripheral vision may make it easier to miss objects, people or obstacles approaching from the side.

Increased Sensitivity to Glare

Bright sunlight, headlights and reflections from shiny surfaces can sometimes make it temporarily harder to see clearly.

For older adults, recovering from glare may also take longer, which can be particularly noticeable while driving or moving between brightly and dimly lit areas.

Small Changes at Home Can Make a Difference

Supporting safer movement doesn't necessarily require major changes to your home.

Start by taking a look at the places you walk through every day.

Keep hallways and stairways well lit, particularly at night. Remove or secure loose rugs and cords that cross walking areas. Consider adding contrast to the edges of steps if they're difficult to distinguish from the surrounding floor.

Nightlights can also make nighttime trips through the house easier to navigate.

And don't forget your glasses. Wearing the correct prescription and keeping lenses clean can help you get the clearest vision possible.

Don't Skip Regular Eye Exams

Changes in eyesight aren't always immediately obvious.

Regular comprehensive eye exams give your eye-care professional an opportunity to evaluate your vision, update your prescription when necessary and look for changes in your eye health.

If you've noticed new difficulty seeing steps, judging distances, navigating in low light or maintaining your balance, it's worth discussing those changes with your healthcare provider or eye-care professional.

Sudden or significant changes in vision should be evaluated promptly.

Healthy Aging Means Looking at the Whole Picture

Preventing falls isn't about focusing on one thing.

Maintaining strength and balance, staying physically active, reviewing medications with your healthcare provider when appropriate, creating a safer home environment and taking care of your vision can all be part of a broader approach to healthy aging.

Your eyesight does much more than help you read a book or recognize a face.

It helps you understand the space around you—and move through it with greater confidence.
