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. Surgical removal of the lens - usually replaced with a plastic intraocular lens.






2. Every _ Hour






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






4. What lens material is the easiest to break?






5. The instrument that contains lenses and can be used to determine a spectacle correction.






6. The smallest unit of lens measure.






7. 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.






8. 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.






9. 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.






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






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






12. A complication of diabetes - progressive damage to the blood vessels of the retina.






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






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






15. A lens with no power.






16. 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.






17. 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.






18. When water is retained and swelling occurs in the cornea.






19. Provide a bigger field of vision.






20. Laser-based - non contact - noon invasive imaging technique.






21. What are plus lenses used to correct?






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






23. Protected health Information






24. The entire area that can be seen when the eye is directed forward including that which is seen with peripheral vision.






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






26. 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.






27. The system for sorting and assigning priorities for medical treatment based on the urgency of the systems.






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






29. What are used to treat dry eyes?






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






31. Inward






32. Downward and inward






33. 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.






34. A topical anesthetic.






35. Two instruments are used to test patient blood pressure.






36. Dilators






37. Downward and diagonally






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






39. 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.






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






41. 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.






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






43. Supplies most of the tears to the eye.






44. Provides nutrients for the lens and posterior cornea.






45. Upward and inward






46. Drop






47. Layers in the cornea

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






50. Is a clouding of the eye's lens and is the leading cause of blindness.
