Explain that myopia, or short sightedness, is caused when distant objects are focused in front of the retina.

In the subtopic The eye (biology only), this learning objective focuses on explain that myopia, or short sightedness, is caused when distant objects are focused in front of the retina. Within The human nervous system, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include myopia, retina, and short sightedness. myopia means a vision condition where distant objects appear blurred because they are focused in front of the retina. Avoid students often think that myopia is caused by the eye being too long rather than understanding that it is due to distant objects being focused in front of the retina; instead clarify that myopia occurs when the light rays from distant objects converge before reaching the retina, leading to blurred vision for far away objects. For exam answers, clearly explain how myopia occurs by stating that distant objects are focused in front of the retina, and use diagrams to illustrate this.
