1. Vision changes
After age 70, common eye conditions such as cataracts, glaucoma, and age-related macular degeneration can significantly impair vision, making driving more hazardous. These conditions reduce the clarity of what you see, diminish contrast sensitivity, and cause glare from oncoming headlights to appear more intense. This can make it difficult to read road signs, detect pedestrians, or respond quickly to changing traffic conditions.
Regular eye exams with an ophthalmologist are crucial to identify and manage these issues early. Updating eyeglass prescriptions or using specialized lenses may improve vision enough to continue driving safely. In some cases, limiting driving to daylight hours or familiar routes can help mitigate risks. However, if vision problems persist or worsen, it is important to consider stopping driving to protect yourself and others on the road.
2. Medication side effects
Many medications commonly prescribed to older adults can cause side effects that impair driving ability. Drowsiness, dizziness, slowed reaction times, blurred vision, and reduced alertness are some of the effects that can compromise safe driving. These side effects can be especially pronounced when multiple medications are taken simultaneously or when dosage changes occur.
It’s essential to carefully read medication labels and discuss potential impacts on driving with your healthcare provider or pharmacist. They can help adjust dosages, recommend alternative treatments, or provide guidance on when it may be unsafe to drive. Never stop or change prescribed medications without consulting the prescriber. Monitoring how you feel after starting new medications and being honest about any side effects can prevent accidents caused by impaired driving.
