How to Be Visual Field Technologist - Job Description, Skills, and Interview Questions

The job of a Visual Field Technologist is to administer tests to evaluate a patient's peripheral vision, tested for central vision, and measure the sensitivity of their eyes. This is an important role in the diagnosis and management of eye diseases. The results of these tests can be used to detect glaucoma, cataracts, macular degeneration, and other retinal diseases.

By accurately assessing the patient's vision, this technologist can provide important information to the ophthalmologist or optometrist. This information can lead to early detection and treatment of these diseases, thus helping to maintain the patient's eye health and prevent vision loss.

Steps How to Become

1. Obtain a High School Diploma or GED. To become a Visual Field Technologist, you will need to have at least a high school diploma or GED.
2. Complete an Associate Degree Program. Most employers prefer to hire visual field technologists who have completed an associate degree program in an area like Ophthalmic Technology.
3. Gain Work Experience. Once you have graduated from your associate degree program, you should look for opportunities to gain work experience in the field. This can be done through internships, volunteer positions, or even part-time jobs.
4. Obtain Certification. After gaining some work experience in the field, the next step is to obtain certification as a Visual Field Technologist. You can do this by passing the Certified Ophthalmic Technician (COT) exam administered by the Joint Commission on Allied Health Personnel in Ophthalmology (JCAHPO).
5. Obtain Licensure. Depending on where you live, you may need to obtain a license from your state's board of optometry before you can practice as a visual field technologist. Licensure requirements vary by state, so make sure to check with your state's board for more information.
6. Stay Up-to-Date on Technology. To stay competitive in this field, it's important to stay up-to-date on the latest technology and trends in the visual field industry. Attend conferences, read industry publications, and participate in online forums to stay informed.

The role of a Visual Field Technologist requires a high degree of skill and competence. To be successful in the role, a person must have the necessary knowledge of the anatomy of the eye and be familiar with the equipment used to measure visual fields. They must also be able to interpret the results and make a diagnosis.

they must be able to communicate effectively with patients, both in person and over the phone. Finally, they must possess strong problem-solving skills to identify any potential issues that may arise during testing and have the ability to work collaboratively with other health care professionals. When all of these elements are combined, it creates a successful Visual Field Technologist who is able to accurately diagnose vision problems and improve the quality of life for patients.
