BFUHS Ophthalmic Officer Previous Year MCQs: Clinical Refraction Solved Paper
Securing a top rank in state optometry recruitment exams requires precision, especially in core clinical subjects. This comprehensive study guide provides a carefully curated set of BFUHS Ophthalmic Officer Previous Year MCQs dedicated entirely to the highly tested subject of Clinical Refraction. By diligently practicing these targeted Ophthalmic Officer MCQs, candidates can sharpen their objective and subjective refraction skills, ensuring maximum accuracy and time management during the written examination.
This specialized practice module breaks down complex clinical scenarios using authentic Ophthalmic Officer Previous Year MCQs accompanied by detailed, step-by-step explanatory answers. In this practice set, you will review and master essential refractive principles, including:
- Retinoscopy Dynamics & Working Distance: Decoding “with” and “against” reflex movements based on varying working distances (e.g., 1m vs. 50cm), and calculating final prescriptions using optical transposition.
- Cycloplegic Refraction: Understanding the standard dioptric deductions required when performing retinoscopy under strong cycloplegics like 1% Atropine.
- Subjective Refraction Tests: Interpreting the Duochrome test responses for under-corrected myopic patients and distinguishing the clinical presentation of near-vision blur in presbyopia versus hypermetropia.
- Refractive Surgery & Classifications: Reviewing the strict contraindications for LASIK surgery (such as the minimum age requirement of 18 years) and defining the clinical components of total hypermetropia (manifest plus latent).
Practice BFUHS Previous Year MCQs on “Clinical Refraction”:
Q-1: While doing retinoscopy from 1m, red reflex moves in the opposite direction to the retinoscope. This indicates: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) Hypermetropia
B) Myopia greater than 1D
C) Myopia of 1D
D) Myopia lesser than 1D
Click “Show more” to see the answer and explanation.
Answer: B) Myopia greater than 1D
When the reflex moves opposite to the retinoscope without working distance power, it indicates myopia greater than the working distance power. With a normal working distance of 1D, this corresponds to myopia greater than 1D.

Q-2: An examiner working at 2/3 m observes against motion when refracting a -2.00D myopic eye (without any lenses being placed in front of the patient). When refracting the same eye at a working distance of 50 cm, he observes neutrality. When the examiner moves to 40 cm, he will observe: (BFUHS Optometry Previous Year Question Paper)
A) With movement
B) Against movement
C) Neutralisation point
D) Scissoring reflex
Click “Show more” to see the answer and explanation.
Answer: A) With movement
At 40 cm, working distance power is 100/40 = 2.5D. Since the patient’s refractive error is -2.0D (less than working distance power), the reflex will be “With Movement”. This follows the basic principle of retinoscopy where neutralization occurs when refractive error equals working distance power.

Q-4: A female patient wants LASIK surgery for her eye. She asks for your opinion. All the following things are suitable for performing LASIK surgery except: (BFUHS Optometry Previous Year Question Paper)
A) Myopia of 4 diopters
B) Stable refraction for 1 year
C) Corneal thickness of 600 microns
D) Age of 15 years
Click “Show more” to see the answer and explanation.
Answer: D) Age of 15 years
LASIK surgery is generally not recommended for patients under 18 years of age because their refractive error may not have stabilized yet. Other parameters like stable refraction, adequate corneal thickness, and appropriate myopia degree are suitable.

Q-5: When a cycloplegic retinoscopy has been performed using atropine (1%), how many dioptres should be subtracted: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) 1.00D
B) 0.75D
C) 0.50D
D) 0.00D
Click “Show more” to see the answer and explanation.
Answer: A) 1.00D
Atropine is a strong cycloplegic that completely paralyzes accommodation. A standard deduction of 1.00 Diopter is made from the retinoscopy findings to account for the loss of ciliary tone and the working distance.

Q-6: In Duochrome test, under corrected myopic patient will see: (BFUHS Ophthalmic officer Previous Year Question Paper)
A) Letters on Red more clearly
B) Letters on Green more clearly
C) Both equally clear
D) Both blurred
Click “Show more” to see the answer and explanation.
Answer: A) Letters on Red more clearly
Red light has a longer wavelength and is refracted less than green light, so it focuses further back in the eye. In an under-corrected myopic eye, the red focus falls closer to the retina than the green focus, making the red background appear sharper.

Q-7: When plane mirror retinoscopy is performed at a distance of 1 m (no cycloplegics used); in myopia less than 1D, the movement of reflex will be: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) With movement
B) Against movement
C) No movement
D) No reflex
Click “Show more” to see the answer and explanation.
Answer: A) With movement
At 1 meter working distance, the neutralization point corresponds to -1.00 D of myopia. If myopia is less than 1.00 D, the far point lies beyond the examiner, resulting in a “with” motion, similar to emmetropia or hypermetropia at this working distance.

Q-8: Blurring of vision for near work occurs in:(BFUHS Ophthalmic officer Previous Year Question Paper)
A) Hypermetropia
B) Presbyopia
C) Both of the above
D) None of the above
Click “Show more” to see the answer and explanation.
Answer: C) Both of the above
Blurring of near vision is the hallmark symptom of Presbyopia due to physiological loss of accommodation with age. It also occurs in uncorrected Hypermetropia when accommodative reserves are insufficient to overcome the refractive error plus near demand.
