Myopia
Myopia is a defect in which a person sees nearby objects clearly but distant objects appear blurred.
Practice This ConceptMain explanation
Teacher explanation
In myopia, light from a distant object is focused in front of the retina instead of on it. This can happen because the eyeball is too long or the eye lens has too much converging power. A concave lens is used for correction because it spreads the rays slightly before they enter the eye.
Example
A student can read a book easily but cannot clearly see the school notice board from the back row.
Simple analogy
Myopia means near clear, far blurred.
Common confusion
Students often say myopia means 'short sightedness' but forget to mention that the image of distant objects forms in front of the retina.
Exam tip
In correction answers, mention concave lens, diverging rays, and image shifting to the retina.
