Quick answer

Safe driving needs clear distance vision, useful side vision, comfortable night vision and the ability to judge speed and distance. Have your eyes tested regularly and wear an up-to-date prescription. See an optometrist if night driving is difficult, glare is worsening, or road signs seem harder to read. If vision suddenly deteriorates, do not drive until assessed.

## Vision skills needed for driving

Driving relies on more than reading a number plate. Peripheral awareness helps at junctions, and contrast sensitivity matters in rain and dusk.

- Clear distance vision for signs, signals and hazards
- Adequate side vision for merging and pedestrians
- Coping with glare from headlights and low sun
- Depth perception and single clear vision, not double

## Common problems that affect drivers

Cataracts cause glare and hazy vision, especially at night. Uncorrected short-sightedness makes signs blurry. Dry eye and unclean windscreens add glare. Some conditions, including advanced glaucoma, reduce side vision and make driving less safe even when central vision seems acceptable.

## Practical steps

Keep your prescription current, clean glasses and mirrors, and use visors against low sun. Allow extra time at night and avoid driving when very tired. An optometrist can advise on tint, varifocals or whether vision meets general safety expectations — legal standards vary by country.

## When to stop and seek advice

Stop driving and arrange an urgent eye test if you develop sudden blurred vision, double vision, a curtain across sight, or severe glare that makes oncoming lights unbearable. Tell your clinician you drive so they can advise on safety.

## Frequently asked questions

### Can I drive with one good eye?

Many people with good vision in one eye drive safely after adaptation, but depth perception may be reduced. An optometrist can discuss individual fitness to drive using general safety principles.

### Do I need special glasses for driving?

Your usual distance prescription is usually enough. Some drivers benefit from anti-reflection coatings or a dedicated driving pair. Sunglasses for day driving should not be too dark.

### Does age automatically mean I should stop driving?

No. Many older drivers have excellent vision with up-to-date glasses. Regular eye exams matter because cataracts, glaucoma and macular disease become more common with age.

Your next step

## Take this to your appointment

Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
