- 1. If u got +0.50/+3.00×180 in your refraction and you realized u need to reduce the cylindrical component by 1.00 what will be your new prescription? (DHA MCQs online)
- A. +0.50/+1.0 x 180
- B. +0.50/+1.0 x 90
- C. +1.0/+2.0 x 180
- D. +1.0/+2.0 x 90
Click “Show more” to see the answer and explanation.
Ans: c. +1.0/+2.0 x 180
If you do Spherical Equivalent of +1, you have to add half of cylinder (+0.50) with the spherical power. So, the final power will be: +1.0/+2.0 x 180
- 2. Which readings have the rule Astigmatism? (DHA MCQs for Optometrist)
- A. 43/44 at 90
- B. 44/44 at 18
- C. 44/46 at 18
- D. 42/46 at 12
Click “Show more” to see the answer and explanation.
Ans: a. 43/44 at 90
Anatomically, vertical meridian is steeper than the horizontal meridian (that is the rule). Keratometer readings are not like optical cross where power is present 90 degree apart. In keratometer power is mentioned meridianwise directly. So, 90 degrees meridian is steeper (44D) than the 180 degrees meridian (43D) that is an example of with the rule astigmatism.

- A. Visual Acuity Test.
- B. AC Angle Evaluation
- C. Refraction
- D. Cup-Disc Ration assessment.
Click “Show more” to see the answer and explanation.
Ans: D. Cup-Disc Ration assessment.
Cupping refers to the optic disc changes that occur in glaucoma. While monitoring and assessing the optic disc cupping is an important part of managing glaucoma, it is not the primary management strategy.
- 4. What telescope used in slit lamp? (DHA MCQs PDF)
- A. Keplerian Telescope
- B. Galilean Telescope
- C. Both A & B
- D. None of these
Click “Show more” to see the answer and explanation.
Ans: B. Galilean Telescope
A Galilean Telescope consists of a positive objective lens and a negative eyepiece lens. It is commonly used in low magnification applications, providing a wider field of view compared to a Keplerian Telescope. In a slit lamp, the Galilean Telescope allows the ophthalmologist to visualize the structures of the anterior segment.
- 5. What is the color of Fluorescein dye when placed in the eye. (DHA MCQs paper)
- A. Red
- B. Blue
- C. Green
- D. Black
Click “Show more” to see the answer and explanation.
Ans: c. Green
Fluorescein dye, when placed in the eye, typically appears as a bright yellow or greenish-yellow color. It is a fluorescent dye that is commonly used in ophthalmology for various diagnostic procedures, such as assessing corneal integrity, detecting corneal abrasions or ulcers, and evaluating tear film dynamics.
- 6. A patient wearing spectacles RE: +8.50/-1.25 x 170 LE: +1.75/-1.25 x 180 appear double vision only when use the spectacles. What is the most likely cause:
- A. Optic center not centred properly
- B. Frame or lens has bent
- C. Presence of manifest squint
- D. None of these
Click “Show more” to see the answer and explanation.
Ans: A. Optic center not centred properly
When Optical center is not aligned it creates prismatic effect. Higher the power higher the prismatic effect. Prismatic effect can lead to diplopia in high powered decanted lens.
- 7. Which condition, enlargement of Blindspot is not seen? (DHA exam questions)
- A. Papilledema
- B. Glaucoma
- C. Diabatic retinopathy
- D. Optic coloboma
Click “Show more” to see the answer and explanation.
Ans: d. Optic coloboma
Optic coloboma is a congenital condition where there is a defect or gap in the structure of the optic nerve or retina. It is present from birth and does not typically cause enlargement of the blind spot. Instead, it can result in a permanent visual field defect in the affected area.
On the other hand, conditions like a. Papilledema, b. Glaucoma, and c. Diabetic retinopathy can cause an enlargement of the blind spot.
- 8. Papilledema has all the following characteristics except: (DHA exam questions for optometrists)
- A. Marked loss of vision
- B. Blurring of disc margins
- C. Hyperaemia of disc
- D. Field defect
Click “Show more” to see the answer and explanation.
Ans: a. Marked loss of vision.
Papilledema is a condition characterized by swelling of the optic disc due to increased intracranial pressure. It is important to note that papilledema itself does not cause a marked loss of vision. The vision loss associated with papilledema is typically secondary to the underlying cause of increased intracranial pressure, such as a brain tumor or intracranial hypertension.
- 9. Which Laser property is least important in ophthalmic application? (DHA question paper)
- A. Energy level
- B. Power level
- C. Pulse duration
- D. Polarity
- E. Focal spot size
Click “Show more” to see the answer and explanation.
Ans: d. Polarity
Polarity refers to the direction of the electrical current flow in the laser system. In ophthalmic applications, the majority of lasers used are not polarity-dependent. The laser beam is usually emitted as a coherent light, and the direction of current flow does not have a significant impact on the effectiveness or safety of the treatment. Instead, other parameters such as energy level, power level, pulse duration, and focal spot size are more crucial in determining the desired therapeutic outcome and minimizing potential risks.
- 10. What is the SI unit of oxygen transmissibility? (DHA question paper for optometrist)
- A. Dk/t
- B. Dt/k
- C. tk/D
- D. t/Dk
Click “Show more” to see the answer and explanation.
Ans: A. Dk/t
Oxygen transmissibility is a measure of how well a contact lens allows oxygen to pass through to the cornea. It is represented by the value Dk/t, where Dk is the oxygen permeability coefficient of the material and t is the thickness of the lens. Dk/t is expressed in units of barrer/cm or barrer/mm, which are the SI units for oxygen permeability.
- 11. Most metabolically active layer of cornea? (DHA questions & answer optometry)
- A. Epithelium
- B. Bowman’s
- C. Stroma
- D. Endothelium
Click “Show more” to see the answer and explanation.
Ans: A. Epithelium
The corneal epithelium is responsible for protecting the eye from external factors, such as dust, debris, and pathogens. It is highly regenerative and has a high metabolic rate to maintain its integrity and perform its functions. The epithelial cells are constantly renewing and have high oxygen and nutrient demands.
- 12. A patient came into the clinic with a habitual Prescription of +1.75 (OU) Add +1.25 after Subject Refraction, we have +2.00(OU) with tentative Add of +1.75 if you decide to give a single prescription for reading, what will you prescribe from the above findings. (MOH exam questions)
- A. +1.25 DS
- B. +1.75 DS
- C. +2.00 DS
- D. +3.75 DS
Click “Show more” to see the answer and explanation.
Ans: D. +3.75 DS
The distance power is added with near power. So single prescription for reading only will be distance power + Near Add or 2.0 + 1.75 = 3.75DS
For only distance power single vision lens power will be +2.00DS
- 13. The commonest cause of low vision in India is? (MOH exam questions for optometrists)
- A. Cataract
- B. Glaucoma
- C. Diabetic Retinopathy
- D. Keratoconus
Click “Show more” to see the answer and explanation.
Ans: A. Cataract

Among the options provided, 0.5% Timolol is the drug commonly used for managing open-angle glaucoma, including cases associated with myopia. Timolol belongs to the class of medications known as beta-blockers, and it works by reducing the production of aqueous humor, the fluid inside the eye that contributes to intraocular pressure.

- A. Diabetic Retinopathy
- B. Hypertension
- C. Both A & B
- D. None of these.
Click “Show more” to see the answer and explanation.
Ans: C. Both A & B
Hard exudates are lipid deposits found in the retina and are commonly seen in both diabetic retinopathy and hypertensive retinopathy. These exudates result from the leakage of lipid-rich fluid from damaged retinal blood vessels in these conditions.
