The following article addresses the difference between a vision screening, which is limited in scope and in what it can detect, and a comprehensive eye examination from an optometrist, which is an essential aspect for testing visual acuity and maintaining eye health.
Vision screening is a limited tool that can be used in certain instances, to determine whether further visual assessment is needed. It is never a substitute for a comprehensive examination from an optometrist or medical ophthalmologist to assess overall eye health.
They are used to identify potential problems, particularly among children, who might require further evaluation by an optometrist or ophthalmologist.
They are not diagnostic tools. Nor are those who generally administer them qualified to do so. Studies show that a vision screening provides less than 4% of what is necessary for a comprehensive eye exam.
Who is Qualified to Give Vision Screening?
Such screening cannot:
Eye examinations include simple tests to assess general vision, as well as more comprehensive examinations for overall eye health. Depending on how extensive the testing an exam can take up to 90 minutes. Exams for the young and healthy are generally shorter in duration and should average under 30 minutes. Many experts recommend that children have a comprehensive examination before beginning grade school, followed by subsequent annual testing. Common tests include:
Who is Qualified to Give An Examination?
Depending on age, health, risk factors, and family history, the length can range from 30 to 90 minutes. Diabetics, the elderly, those with high blood pressure, and other health conditions require more extensive testing.
Comprehensive testing involves administering drops to dilate the pupils, which enables a thorough assessment of the entire region
Standard methods include:
As a preliminary tool, vision screening may occasionally identify certain eye complications, particularly in the case of schoolchildren. However, their ability to do so is statistically poor. The American Optometric Association (AOA) emphasizes that vision screenings are not the same as comprehensive eye examinations, and that extensive eye tests are essential for children to have success in school.
Some key statistics detailing the poor track record of vision screening include the following:
My eight year old daughter was terrified to go to the eye doctor for fear of her eyes being dilated. The doctor was SO KID friendly! He immediately made her comfortable by engaging her in conversation. It was a geat experience.
Dr. Garbus spent an amazing amount of time to solve my very complicated visual problems. Over the years he has continually achieved results beyond what others felt possible. He is always up to date on the latest science. He is great!
Family Vision Care Valencia makes it so easy. Staff is knows what they are doing and Dr. Garbus is thorough and kept me well informed during the exam.
I have been coming to Family Vision Center for almost 20 years. Dr. Garbus has been able to help my vision when other doctors could not. Now my kids see him as well. I highly recommend this office!
The Doctor is very good. I felt on this visit he seemed rushed. I had questions to ask him but he was already with another patient. I still do not know if my eyes are the same , worse, or better.
All the staff is friendly, helpful and knowledgeable, and has been for all the years I have been going there.
