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. The part of the retina responsible for sharp - clear vision.






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






3. 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.






4. Dilators






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






6. A lens with no power.






7. Computer-assisted method of mapping the surface curvature of the cornea.






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






9. Drop






10. If a patient claims to have pain in the ye but does not have any other symptoms - when do you schedule them for an appointment?






11. Protected health Information






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






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






14. Downward and inward






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






16. The result of the refraction depends on the patient's ability to discern changes in clarity. This process relies on the cooperation of the Patient.






17. At bedtime






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






19. Right eye (OD)






20. Inward






21. By mouth






22. What are used to treat dry eyes?

24. 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.






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






26. What are plus lenses used to correct?






27. Glaucoma causes...






28. The smallest unit of lens measure.






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






30. What does a tonometer measure?






31. What lens material is the easiest to break?






32. The Examination of the inside of the eye.






33. A group of diseases that can damage the eye's optic nerve and result in the vision loss and blindness. It occurs when the normal fluid pressure inside the eyes slowly rises.






34. 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.






35. One type of contact lens is applied after waking and removed before going to sleep.






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






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






38. Controls the focusing power of the eye by changing the shape of the lens.






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






40. Tropicamide - Atropine - Scopolamine - Phenylephrine






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






42. Refers to imaging by section or sectioning - through the use of any kind of penetrating wave.






43. A topical anesthetic.






44. Upward and inward






45. 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.






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






47. Provides nutrients for the lens and posterior cornea.






48. Its purpose: Improve the portability and continuity of health insurance overage - improve access to long-term care services and coverage - to simplify administrative care.






49. A mid-index lens material that is thinner than glass or CR-39 - free from distortion and aberration and able to be used as a safety lens.






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