Monofocal lenses correct vision at a single distance, while multifocal and trifocal lenses extend functional range. The cost difference reflects both optical capability and long-term value.
Monofocal lenses
- Single focal point
- Excellent contrast sensitivity
- Lower device cost
- May require glasses for reading or intermediate tasks
Multifocal/trifocal lenses
- Multiple focal points
- Higher spectacle independence
- More complex optics
- Higher device cost
- Require detailed counselling
Cost comparison
- Monofocal RLE: lower end of the £3,500-£6,000 range
- Multifocal/trifocal RLE: upper end of the range
Long-term value
Patients choosing monofocal lenses may incur ongoing spectacle costs, whereas premium lenses reduce long-term optical dependence.
