Verified step by step guidance

Understand the key terms provided in the question: Refraction, Convergence, Adaptation, and Accommodation. Each term relates to the eye's ability to process light and focus images on the retina.

Define 'Refraction': Refraction is the bending of light rays as they pass through different mediums, such as the cornea and lens, to focus light on the retina.

Define 'Convergence': Convergence refers to the inward movement of the eyes to focus on a nearby object, ensuring the image falls on corresponding points of the retina in both eyes.

Define 'Adaptation': Adaptation is the eye's ability to adjust to varying levels of light, such as transitioning from a bright environment to a dark one.

Define 'Accommodation': Accommodation is the process by which the lens changes shape (becomes thicker or thinner) to focus light on the retina for clear vision at different distances.
