Can I drive at night with contact lenses?

For most wearers night vision is the same with contacts as with glasses, and often better (no frame reflections, no rain on lens surface). Three caveats:

• Multifocal lenses: the concentric zones can produce mild halos and starburst around point sources (oncoming headlights, street lamps). Most wearers adapt within 2–3 weeks. A few don't — multifocal contacts may not be the best choice for nightly long-distance driving.
• Late-day dryness: tired, dry eyes scatter more light, reducing contrast at night. Use re-wetting drops 30 minutes before night driving.
• Old lenses: deposits scatter light. Don't drive at night on a lens that's past its replacement interval.

If night vision is markedly worse with lenses than glasses, ask your optician — the prescription or material may need fine-tuning.
