In the context of vision impairment, "best conventional correction" specifically describes the level of visual acuity that a person can achieve when using corrective lenses, such as glasses or contact lenses. This term emphasizes the importance of optical aids in helping individuals achieve their highest potential vision, enabling them to function more effectively in daily activities.

When assessing a person's vision, it is not just about measuring their uncorrected vision—meaning vision without any assistive devices—but rather evaluating how much their vision can be improved through these conventional corrections. This distinction is crucial for understanding how visual impairments are addressed in clinical and educational settings, as it informs decisions about appropriate interventions and support.

The other concepts, such as the average vision of the population or vision without any aids, do not provide a focused understanding of the role of corrective lenses in enhancing visual acuity for individuals with vision impairment. The term underscores the significance of providing appropriate optical corrections to optimize an individual’s visual capabilities.
