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. What are plus lenses used to correct?






2. At bedtime






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






4. 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.






5. A paralysis of the ciliary muscle - so accommodation can't occur.






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






7. 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.






8. Proparacaine - Tetracaine - Cocaine






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






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






11. The creation of a photograph of the interior surface of the eye.






12. The Examination of the inside of the eye.






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






15. Layers in the cornea






16. As needed






17. The lifeline into and out of the practice.






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






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






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






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






22. Supplies most of the tears to the eye.






23. 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.






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






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






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






27. What are used to treat dry eyes?






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






29. 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.






30. What does a tonometer measure?






31. 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.






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






33. Protected health Information






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






35. By mouth






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






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






38. A topical anesthetic.






39. Drop






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






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






42. A lens with no power.






43. 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.






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






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






46. Outward






47. The smallest unit of lens measure.






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






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






50. 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.
