Certified Paraoptometric Exam

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Located behind the pupil - and is the secondary mechanism of focus - adjusting the amount of focus the light image requires before it reaches the retina.






2. The measure of the finest detail the eye may detect.






3. Associated with aging and results in damaging sharp and central vision.






4. Corrects one eye for distance and the other eye for near and can be used to correct presbyopia.






5. Increases visual acuity because it reduces internal lens reflections.






6. A layer located behind the retina and absorbs unused radiation.






7. The portion of the optic nerve that is formed by the meeting of all retinal nerve fibers.






8. A jelly-like subastance located in the anterior chamber.






9. What is the name for the part of the frame that connects the two eyewires?






10. Involves an imbalance in the positionig of the two eyes. I can cause the eys to cross in or tuyrn out. It's cause by a lack of coordination between the eyes.






11. The nerve center of the eye where light is converted into an electrical signal that travels along the optic nerve to the brain.






12. Protected health Information






13. This is the pathway between the ye and the brain along which the signals produced by the retina travel to the brain.






14. What is the primary function of the inferior rectus muscle?






15. A test that measures the pressure inside your eye - which is called intraocular pressure.






16. What's it called when the cornea thins and bulges forward?






17. Provides nutrients for the lens and posterior cornea.






18. What provides the major refractive power of the eye?






19. A test that allows a doctor to see inside the back of the eye and other structures using a magnifying instrument and a light source.






20. The smallest unit of lens measure.






21. The gel that fills the eye and allows it to maintain its shape. Also serves as a clear pathway for light when it travels from the lens to the retina.






22. The chart most often used to measure acuity at distance.






23. Downward and inward






24. Glaucoma causes...






25. Tropicamide - Atropine - Scopolamine - Phenylephrine






26. Diabetic patients may have vision loss due to...






27. The Examination of the inside of the eye.






28. What are plus lenses used to correct?






29. The ability to maintain visual focus on an object with both eyes creating a single visual image.






30. The light sensitive part of the eye.






31. The lifeline into and out of the practice.






32. Numerous different surgeries that facilitate the escape of excess aqueous humor from the eye to lower the intraocular pressure and a few that lower IOP by decreasing the production of aqueous humor.






33. Measurement of the form and curvature of the cornea.






34. Swelling or infection of the membrane lining the eyelids or Conjunctiva.






35. Upward and diagonally






36. A method of determining the state of refraction of the eye by illumination the retina with a mirror and observing the direction of movement of the retinal illumination and adjacent shadow when the mirror is turned.






37. What lens material is the easiest to break?






38. Which type of lens will have the same power in all areas of the lens?






39. The Optothalmic examination of the eye by use of a slit lamp and a magnifying lens.






40. Back vertex power which includes sphere and cylinder power.






41. The procedure using ultraviolet radiation from a laser to remove tissue.






42. Provide a bigger field of vision.






43. Inward






44. Proparacaine - Tetracaine - Cocaine






45. What does a tonometer measure?






46. The distance from the back surface of the lens to the front of the eye.






47. Ultraviolet Coating protect the eye from damaging...






48. A broken blood vessel between the sclera and conjunctiva.






49. Transparent covering of the eye that lies between the eyelid and front of the eye.






50. The distance between the center of the pupil of each eye.
