Accommodation
Accommodation is the visual system’s ability to adjust its focus in order to see objects at different distances clearly. It is a fundamental function for near vision and for rapidly shifting focus between different distances.
Key features
The Accommodation allows you to adjust your focus when switching between distance and near vision. This function is essential for activities such as reading, using a smartphone, working on a computer and carrying out tasks requiring precision.
How does the Accommodation work?
- Focus adjustment — The visual system adjusts its optical power to bring nearby objects into focus.
- Automatic reply — The Accommodation is triggered automatically when the object approaches.
- Coordination with convergence — It works in conjunction with eye movements to maintain single vision.
Relationship with other visual functions
The Accommodation is closely linked to near vision and the stability of binocular vision.
- Convergence — Focusing the eyes on a nearby point.
- Binocular vision — Integration of the images from both eyes.
- Presbyopia — A natural reduction in the eye’s ability to focus as we get older.
- Eye dominance — A natural preference for one eye.
Optical solutions
When the accommodative demand is high or prolonged, certain optical solutions can improve visual comfort during near and intermediate tasks.
- Office lenses — Optimised for medium and close-range distances.
- Progressive lenses — To combine multiple focal lengths into a single lens.
- Single-vision lenses — For clear vision at a single distance.
