PRESBYOND can markedly reduce dependence on spectacles, but complete freedom from glasses in all situations cannot be guaranteed.
How it can reduce glasses use
Blended vision covers multiple distances.
- Improved unaided distance, intermediate, and near vision for most daily tasks
- Less reliance on reading and varifocal glasses
- Particularly helpful for active lifestyles and varied working distances
- Backup spectacles usually only needed for very fine print or demanding conditions
- High satisfaction when expectations are realistic
Limits to full independence
Some spectacle use remains common.
- Ageing changes and minor regression can occur over time
- Night driving or prolonged fine work may still benefit from glasses
- Residual refractive error or dry eye can affect clarity
- Other eye diseases may later reduce spectacle‑free vision
- Patients must accept trade‑offs such as possible halos or contrast changes
