  • 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.

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






2. Every _ Hour






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






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






5. When the vision in one of the eyes is reduced because the eye and the brain aren't working together properly. The eye itself may look normal - but it's not being used normally because the brain is favoring the other eye.






6. Provide a bigger field of vision.






7. 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.






8. Upward and inward






9. Downward and diagonally






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






11. An ophthalmic stain - available in liquid form and is the most commonly used ophthlmic dye.

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






14. Supplies most of the tears to the eye.






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






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






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






19. Layers in the cornea






20. Downward and inward






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

25. What are cycloplegic drugs used for?






26. 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.






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






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






29. Dilators






30. 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.






31. Proparacaine - Tetracaine - Cocaine






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






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






34. The lifeline into and out of the practice.






35. Right eye (OD)






36. What are used to treat dry eyes?

40. What are plus lenses used to correct?






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






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

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






45. As needed






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






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






48. Outward






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






50. 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.
