Ocular Dominance
Ocular Dominance is the natural preference that the visual system attributes to one of the two eyes during the perception and processing of images. It does not imply that one eye is ‘better’ or ‘worse’ than the other, but simply indicates which eye is used as the primary reference.
Key features
The Ocular Dominance is similar to a manual preference (right-handed or left-handed). The dominant eye serves as the primary reference point for the perception of position, depth and visual alignment. It is a stable and natural characteristic.
Types of dominance
- Sensory dominance — One eye makes a greater contribution to perception.
- Motor dominance — One eye plays a greater role in guiding alignment movements.
- Directional dominance — Preference for alignment during specific activities.
Relationship with other visual functions
Ocular Dominance affects various aspects of binocular vision and may be a factor to consider when choosing bespoke optical solutions.
- Binocular vision — Integration of images from both eyes.
- Convergence — Focusing the eyes on a nearby point.
- Accommodation — Focusing at different distances.
- Heterophoria — A latent tendency for the eyes to become misaligned.
Impact on optical solutions
Ocular Dominance can influence the choice and customisation of lenses, particularly in solutions that require balance between the two eyes or in specific configurations.
- Progressive lenses — Dominance can influence the distribution of visual zones.
- Office lenses — Optimised for close-up and medium-range tasks.
- Single-vision lenses — For clear vision at a single distance.
Isolani Experience
At Isolani Optical Centres, we regard Ocular Dominance as an integral part of the lens customisation process, to ensure natural, stable and comfortable vision in all everyday activities.
- Personalised eye care advice — Analysis of visual needs and lifestyle.
- Behavioural Centring — Detection based on actual visual behaviour.
- Simulation Room — Evaluation of optical solutions under real-world conditions.
Ongoing support
Your Ocular Dominance remains stable over time, but your visual needs may change. At Isolani Optical Centres, we offer ongoing support through non-medical eye tests and updates to your personalised optical solutions.
