People who drive extensively at night require extra caution with PRESBYOND, because blended‑vision profiles can increase halos and reduce contrast in low light.
Potential benefits
Reduced spectacle juggling may help.
- Good unaided distance and dashboard vision once adapted
- Less reliance on varifocal glasses that distort peripheral view
- Convenience for frequent evening or night journeys
- Useful for those who struggle with contact lenses during long drives
- Many patients drive comfortably at night after recovery
Reasons for caution
Night‑time performance must be preserved.
- Higher likelihood of halos around headlights and streetlights
- Large pupils and pre‑existing glare increase the chance of symptoms
- Professional or heavy night drivers may find even mild phenomena problematic
- Alternatives such as monovision or lens‑based options may be safer
- Some patients may continue to use glasses for the most demanding night driving
