Showing 1–6 of 6 questions
Q1 · Myopia
NEET PGEasyExplanation
In myopia the eye is too long, or too powerful, so light focuses in front of the retina, blurring distance vision. It is corrected with a concave (minus) lens. Hypermetropia is the opposite, corrected with a convex (plus) lens.
Q2 · Hypermetropia
EasyExplanation
In hypermetropia light focuses behind the retina, so a convex (converging, plus) lens is used to bring the focus onto the retina. Myopia, in contrast, is corrected with a concave (minus) lens.
Q3 · Astigmatism
MediumExplanation
Astigmatism arises from unequal corneal, or lens, curvature in different meridians, and is corrected with a cylindrical lens that compensates for the differing refractive power. It commonly coexists with myopia or hypermetropia.
Q4 · Presbyopia
NEET PGEasyExplanation
Presbyopia is the age-related decline in the lens's ability to accommodate, typically from the 40s, causing difficulty with near vision. It is corrected with convex reading glasses or bifocals.
Q5 · Amblyopia
MediumExplanation
Amblyopia is reduced vision in an eye that did not develop normal sight in childhood, from strabismus, refractive error, or deprivation. Treatment — correcting the cause and patching the good eye — is most effective in early childhood, before the visual system matures.
Q6 · Strabismus
MediumExplanation
The cover-uncover test detects manifest and latent squints by observing eye movement when each eye is covered and uncovered. The corneal light reflex (Hirschberg) test also helps assess ocular alignment.
Optics and Refraction sits within Ophthalmology, which carries the same syllabus in both exams. This set runs to 6 questions, each tagged Easy, Medium or Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Optics and Refraction marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Ophthalmology examiners keep returning to.
