Multifocal lenses cause specific visual phenomena including halos, starbursts, and glare around bright lights, especially during night driving. These effects stem from the lens design splitting light into multiple focal points. While offering clear vision at various distances, patients often require three to six months for neurological adaptation.
- Visual disturbances: Seeing rings or starbursts around headlights specifically due to the multifocal ring design.
- Contrast sensitivity: Colors may appear less crisp or slightly washed out in low-light environments.
- Neurological adaptation: The brain requires significant time to learn how to process simultaneous focal points.
- Ghosting effects: Some patients perceive a secondary blurry image alongside the primary clear one initially.
Bookimed Expert Insight: Choosing a high-volume surgeon is critical because they better manage the specific neuroadaptation phase. For instance, Dr. Pichit Naripthaphan at TRSC International Eye and Vision Center has performed over 12,000 surgeries. Experts like him often suggest trying multifocal contact lenses before surgery to simulate the visual trade-offs firsthand.
Patient Consensus: Many describe nighttime driving as looking through a kaleidoscope due to the intense halos. While most adapt, some patients find the reduced contrast in dim rooms annoying and suggest sticking to monofocal lenses if night vision is your top priority.
