How is vision impairment linked to an increased risk of falls in people over 65?

✓ Accepted answer

Vision impairment increases fall risk by reducing an older adult’s ability to accurately perceive depth, distance, and ground obstacles, leading to misjudged steps and loss of balance.

• Heightened Physical Hazard Awareness: Blurred vision or narrowed fields of view prevent individuals from seeing curbs, uneven flooring, or shadows that mimic steps. The CDC notes that one in four Americans over 65 falls annually, and impaired visual processing is a primary contributor to these preventable injuries.
• Systemic Condition Overlap: Eye diseases like diabetic retinopathy, cataracts, and macular degeneration frequently coexist with heart disease and stroke. These chronic conditions can simultaneously compromise mobility and visual acuity, creating a compounding effect on fall risk.
• Medication Side Effects: Prescriptions for heart, blood pressure, or mood disorders often cause dizziness, lightheadedness, or muscle weakness. When these side effects intersect with compromised vision, a person’s reaction time to a stumble is significantly slower, increasing the likelihood of a hard fall.
• Perception Gaps and Screening: A 2026 study in npj Aging found that nearly 50 percent of eyes with objective visual impairment did not report subjective symptoms. Because many older adults are unaware of their declining vision, routine objective screening is critical to catch issues before they contribute to injury.
• UK and US Safety Measures: In the UK, the NHS provides free sight tests, while private specialist clinics offer rapid access to targeted care. In the US, regular check-ups with optometrists or ophthalmologists are recommended to monitor conditions like glaucoma and update prescriptions to ensure adequate light sensitivity and clarity.
