Multifocal contact lenses contain zones or gradients of different powers to provide vision at distance and near, helping manage presbyopia without constant spectacle use. Designs vary between manufacturers.
How They Work
Some lenses use concentric rings of distance and near power, while others employ aspheric profiles that blend powers smoothly. The brain learns to select the appropriate focus depending on the task.
- Available in soft and some rigid or scleral materials
- Can be combined with monovision strategies in selected cases
- Fitting often involves trialling different designs and power balances
- Lighting and contrast can influence perceived quality of vision
Expectations and Adaptation
Multifocal lenses can reduce dependence on reading glasses but may involve some compromise in clarity or contrast, especially in low light. Careful counselling and follow‑up optimise satisfaction.
- Provide feedback on real‑world tasks such as driving and reading
- Fine‑tuning may require several visits and prescription adjustments
- Not everyone achieves complete spectacle independence
- Regular aftercare ensures continuing corneal health and performance
