Heavy night drivers require extra caution with PresbyMAX, because multifocal laser profiles can increase halos and reduce contrast in low light.
Potential benefits
Reduced spectacle juggling may help.
- Improved unaided distance and dashboard vision
- Less reliance on varifocals that can distort peripheral view
- Convenience during frequent night journeys
- Useful for drivers who dislike or struggle with contact lenses
- Good outcomes in many patients with modest night‑time demands
Reasons for caution
Night‑time quality must remain high.
- Increased risk of halos around headlights and streetlights
- Large pupils exacerbate optical side‑effects
- Professional or extensive night drivers may find even mild phenomena problematic
- Alternatives such as monovision or lens‑based options may be safer
- Some patients may still prefer glasses for the most demanding night driving
