Common Tests

 eye doctor with scopeWhile there are some basic eye vision tests common to most eye exams, children and young adults have different vision testing needs than say, a healthy middle-aged adult, or an adult with a history of eye problems.

Vision testing equipment ranges from simple tools like the “Big E” eye chart (Snellen Chart) and a hand-held penlight and eye cover, to more complex devices that swap lenses in front of your eyes or use special lamps to view the eye’s structure. A comprehensive eye exam includes vision testing, and vision testing equipment that is common to almost all eye exams, but is often tailored to your age, your specific need, or your individual symptoms. The following are some common tests you may be given during a routine eye exam.

  • An ophthalmoscope is a handheld device used to examine your eye’s interior structure, including the retina.
  • Optomap® is new technology that allows for detailed retina examination without dilating pupils. 
  • Peripheral vision testing is the part of the eye exam that tests the “outside” of your vision.
  • A phoropter is an instrument used to test individual lenses on each eye during an exam.

COVID-19 Update

Your health and well-being is our top priority at Focusing on Eye Care. In following recommendations provided by the CDC, we have implemented protocols at our office in order to continue to protect the health of our patients and our team.

Every patient and their guest will be asked to fill out a COVID-19 questionnaire. Should you or a guest have flu-like symptoms, fever, exposure to a known person with COVID-19 or have tested positive for COVID-19, you will be asked to reschedule your appointment for a later date until you are well or clear of any potential illness for a minimum of 14 days.

We ask that patients please come to their appointment unaccompanied. If you are requiring a guest to accompany you, we are limiting the number of guests in our facilities to 1 per patient, and we ask that you only bring a guest with you if it is absolutely necessary to avoid crowding in the office.

In addition, we are requiring all employees, patients, and their guests to wear face coverings while in our facilities at all times.

Thank you for all your cooperation as we continue to help you with your eye care needs and for helping us reduce the spread of COVID-19.

Stay Well,

Focusing on Eye Care
