Refraction in the context of vision refers specifically to the bending of light as it passes through different mediums, which is essential for focusing light onto the retina. This process is fundamental to how the eye functions.

When we talk about determining refractive errors, we are essentially assessing how well light is focused in the eye. Refractive errors occur when light rays entering the eye do not focus directly on the retina, leading to blurred vision. The assessment of these errors is crucial in determining the need for corrective lenses, such as glasses or contact lenses.

Thus, the answer regarding the process of determining refractive errors aligns with the concept of refraction, as it addresses the underlying issues connected to how light is focused and the subsequent impact on vision clarity. This assessment allows eye care professionals to prescribe appropriate corrective measures, making it central to the understanding of refraction in vision.
