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.

2. The Examination of the inside of the eye.






3. Every _ Hour






4. Supplies most of the tears to the eye.






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






6. Constrictors






7. 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.






8. What are used to treat dry eyes?






9. The two main types of filing systems.






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






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






12. 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.






13. 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.






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






15. 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.






16. What are plus lenses used to correct?






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






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






19. Upward and inward






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






21. The smallest unit of lens measure.






22. Outward






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






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






25. 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.






26. The light sensitive part of the eye.






27. Proparacaine - Tetracaine - Cocaine






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






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






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






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






32. Provide a bigger field of vision.






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






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






35. What is the frame height - the most vertical dimension of the lens opening also known as?

36. What does a tonometer measure?






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






38. Layers in the cornea






39. Tropicamide - Atropine - Scopolamine - Phenylephrine






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






41. Upward and diagonally






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






43. Right eye (OD)






44. What lens material is the easiest to break?






45. 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.






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






47. What are cycloplegic drugs used for?






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






49. 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.






50. The interior portion of the eyeball that may be seen on ophthalmoscopy.
