After watching, test yourself with the interactive quiz below. Interactive Score Tracker Correct: 0 Wrong: 0 Attempted: 0/10 Accuracy: 0% Question 1 of 10 AIIMS Optometry PYQs Q-1: Which of the following formulae regarding decentration is correct? (P = Prism power in dioptre, c = Decentration in centimeter, F = Lens power in dioptre) A P = c + F B P = c − F C P = c × F D P = c / F # AIIMS Optometry PYQs 💡 Explanation (Answer: C) This formula represents Prentice's Rule, which is essential in dispensing for calculating induced prism. It states that the prismatic effect is equal to the product of the decentration distance in centimeters and the dioptric power of the lens. Question 2 of 10 AIIMS Optometry PYQs Q-2: Supra frames are most commonly called ______ frames. A Full rim B Rimless C Double bridge D Half rim # AIIMS Optometry PYQs 💡 Explanation (Answer: D) Supra frames typically feature a rigid rim across the top of the lens and a nylon cord securing the bottom. This design is widely referred to as a half-rim or semi-rimless frame. Question 3 of 10 AIIMS Optometry PYQs Q-3: Which of the following pairs regarding ophthalmic lenses is correct? I. Plus lenses are the combination of prisms base to base. II. Minus lenses are the combination of prisms apex to apex. A Both I and II B Neither I nor II C Only II D Only I # AIIMS Optometry PYQs 💡 Explanation (Answer: A) A convex (plus) lens converges light and can be conceptualized as two prisms joined at their bases. Conversely, a concave (minus) lens diverges light and resembles two prisms joined at their apices.

The maximum refractive power is found at the meridian 90 degrees perpendicular to the cylinder axis. Question 5 of 10 AIIMS Optometry PYQs Q-5: Cellulose nitrate is used as a material for spectacle frames. Which of the following characteristics of this material is NOT correct? A Frames are made from sheets made of this material. B It is derived from cotton lint. C It is hard. D It is non-flammable. # AIIMS Optometry PYQs 💡 Explanation (Answer: D) Cellulose nitrate is an older frame material that is chemically unstable and highly flammable. Due to this safety hazard, it has largely been replaced by safer materials like cellulose acetate. Question 6 of 10 AIIMS Optometry Previous Year MCQs Q-6: Lenses with one segment for near vision and one segment for far vision are called ________. A Bifocal B Monofocal C Concave focal D Trifocal # AIIMS Optometry Previous Year MCQs 💡 Explanation (Answer: A) Bifocal lenses are designed with two distinct optical powers within a single lens to address presbyopia. One section corrects distance vision, while the other segment aids in near vision tasks.

A Difference B Summation C Product D Division # AIIMS Optometry Previous Year MCQs 💡 Explanation (Answer: B) For a thin lens, the total power is calculated by adding the dioptric power of the front surface to the dioptric power of the back surface. This algebraic summation is a fundamental concept in lens surfacing and design. Question 8 of 10 AIIMS Optometry Previous Year MCQs Q-8: Which of the following options is not used for correcting unilateral aphakia? A Anterior chamber intraocular lens B Posterior chamber intraocular lens C Contact lens D Glasses # AIIMS Optometry Previous Year MCQs 💡 Explanation (Answer: D) Spectacles are generally not used for unilateral aphakia because the high plus power causes significant image magnification (aniseikonia). This size difference between the two eyes prevents binocular fusion, unlike contact lenses or IOLs. Question 9 of 10 AIIMS Optometry Previous Year MCQs Q-9: Which class of lens is used to correct myopia (short-sightedness)? A Convex lens B Concave lens C Bipolar lens D None of the above # AIIMS Optometry Previous Year MCQs 💡 Explanation (Answer: B) Myopia causes light to focus in front of the retina, requiring a lens that diverges light rays. Concave (minus) lenses push the focal point back onto the retina to restore clear distance vision. Question 10 of 10 AIIMS Optometry Previous Year MCQs Q-10: What is the purpose of prism correction in eyeglasses for people with diplopia (double vision)? A To magnify the images seen by both eyes B To eliminate the need for wearing eyeglasses C To align the two separate images into one image D To enhance the brightness and contrast of the images # AIIMS Optometry Previous Year MCQs 💡 Explanation (Answer: C) Prisms in eyeglasses deviate the path of light to compensate for eye misalignment. This helps fuse the two separate images into a single, clear image, thereby eliminating double vision. 🔒 Bonus MCQs – Available in App Unlock these 5 exclusive premium questions + all 15 clinical subjects in the Govt Job Preparation course.
