Question
How do spectacle lenses correct myopia?
Answer
Spectacle lenses correct myopia by diverging light rays before they enter the eye. This adjustment allows the light to focus further back on the retina, enabling distant objects to be seen clearly.
Explanation
This answer is strong because it clearly explains the mechanism by which spectacle lenses function to correct myopia, demonstrating an understanding of the relationship between lens shape and light refraction. The question tests the student's ability to describe a specific corrective process related to vision.
Common mistake
Misunderstanding Lens Function
Students often confuse how spectacle lenses correct myopia and hyperopia, thinking they simply magnify or reduce size rather than changing the refraction of light.
Emphasize that spectacle lenses adjust the path of light entering the eye to ensure it focuses correctly on the retina, rather than just altering the image size.
