  • 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. What are plus lenses used to correct?






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






3. 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.






4. The Optothalmic examination of the eye by use of a slit lamp and a magnifying lens.






5. Right eye (OD)






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






7. Provides nutrients for the lens and posterior cornea.






8. 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.






9. Provide a bigger field of vision.






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






11. Glaucoma causes...






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






13. Outward






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






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






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






17. A topical anesthetic.






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






19. Drop






20. Protected health Information






21. By mouth






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






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






24. What does a tonometer measure?






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






26. Dilators






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






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






29. The smallest unit of lens measure.






30. What are cycloplegic drugs used for?






31. 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.






32. Supplies most of the tears to the eye.






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






34. Inward

37. Constrictors






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






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






40. Downward and diagonally






41. 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.






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






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






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






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






46. The light sensitive part of the eye.






47. 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.






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






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






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