Falls Prevention: The Role of Good Vision
Falls are a serious concern for older adults. Beyond the immediate injury, a fall can lead to loss of confidence, reduced mobility, and loss of independence. While many factors contribute to falls, poor vision is one of the most significant and one of the most treatable.
Clear sight helps us navigate our environment safely. We need to see obstacles, judge distances, perceive changes in floor level, and detect hazards like trailing cables or wet surfaces. When vision deteriorates, these abilities are compromised, often without us fully realising how much we're compensating.
Several aspects of vision affect balance and safety. Distance vision helps us see where we're going. Near vision matters for seeing where we're placing our feet. Contrast sensitivity determines how well we detect edges and changes in surface. Peripheral vision alerts us to hazards approaching from the side. Depth perception helps us judge steps and kerbs. Problems with any of these increase falls risk.
Common eye conditions in older adults directly affect these functions. Cataracts reduce clarity and scatter light, impairing contrast sensitivity. Glaucoma can narrow the visual field, removing peripheral awareness. Macular degeneration affects central vision used for detecting obstacles ahead.
Glasses themselves can contribute to falls if not optimised. Outdated prescriptions mean the world isn't as clear as it could be. Dirty or scratched lenses reduce contrast. Poorly fitting frames that slip down the nose force people to tilt their heads awkwardly. Varifocals, while excellent for many tasks, can cause problems on stairs because the reading portion at the bottom of the lens blurs the view of steps.
Simple steps reduce risk. Keep prescriptions current. Have separate glasses for tasks where varifocals might be problematic. Ensure adequate lighting, particularly on stairs and in hallways. Remove hazards that poor vision might miss.
At Atlantic Home Eyecare, we consider our patients' overall safety and independence, not just their ability to read letters on a chart. If you or someone you care for has experienced falls, or if mobility is already a concern, ensuring vision is optimal is an important preventive measure.
