INTRODUCTION  \nGood vision is a precious gift, which should be guarded, cherished, and nurtured throughout life. To maintain good vision, frequent vision screenings and periodic visual exams are necessary. In this way, an awareness of inadequate vision or changes in vision can be noted. The eye-care professional can then correct most visual problems. Without these screenings, many children and adults would have undetected visual difficulties, having a direct effect on their quality of life.  \nEye-care professionals feel that the earlier vision screening can begin, the more rewarding the results can be. This attention should be continued throughout adult life, with specific attention to the working years.  \nStereo Optical's OPTEC® 1000 Vision Tester does this screening very efficiently. It is a precision instrument designed to do quick, accurate, reliable, and confidential screening. It will identify those who have a problem and need professional assistance.  \nTHE OPTEC® 1000 VISION TESTER  \nThe OPTEC® 1000 is engineered for ease of use. The instrument is automatic with no moving parts. The instrument weighs only 12 pounds and has a convenient handle for easy portability. The OPTEC® 1000 can be used on a desk, tabletop or countertop, requiring less than two square feet of space. All tests are concealed in a closed housing which allows only the subject being tested to view the targets.  \nThe disposable headrest tissues insure the applicant a hygienic environment. The headrest also triggers the illumination for the test when pressure is applied. If the subject backs off or is in the wrong position, there will be no light in the instrument.  \nAll tests required have been mounted on one easy to change slide.  \nFor the operator, all switches are conveniently located on a remote control panel that can be placed anywhere for the operator's convenience. Each switch is color coded for immediate identification.  \nII. VISION TESTING  \nTo be a skillful tester you must become familiar with the OPTEC® 1000 Vision Tester.  \nLook into the instrument and note what happens when the eyeswitches are ON and OFF. It is important to recognize whatever the subject may be describing and be able to answer any questions. Concentrate on acquiring a smooth delivery of instruction and description of the test target. The tester's expertise can help relax the subject, get better cooperation and a more accurate response.  \nWhen speaking to the subject, never act surprised or provoked by their responses or lack of response. Give the subject every opportunity to demonstrate their best vision.  \nIf the subject is wearing glasses or contact lenses, they should wear them during the testing to determine whether they meet the requirements for corrected vision.  \nThe table or counter should be of convenient height with sufficient surface space for the instrument. Normal room lighting is acceptable, but care should be taken to avoid light shining on the lenses or on the subject's face.","cbCainUumphQ3t5C","https://ap.wps.com/l/cbCainUumphQ3t5C","pdf",2770063,26,"English","# I.
