Headset Instructions

Eye charts measure only visual acuity, which is just one component of good vision. They cannot determine if your eyes are "working overtime" (needing to focus more than normal, which can lead to headaches and eye strain) or can they determine if your eyes work properly as a team for clear, comfortable binocular vision and accurate depth perception. Eye charts also cannot detect serious eye problems such as glaucoma or early diabetic retinopathy that could lead to serious vision impairment and even blindness. Only a comprehensive eye exam performed by a licensed optometrist or ophthalmologist can determine if your eyes are healthy and you are seeing as clearly and comfortably as possible.

Digital Eye Exam Instructions

Ensure proper room lighting and set device brightness to 100%.

Ensure the mic is enabled and that the website has permission to record audio.

Wear the headset and adjust the size of the headset to a good fit.

Select an appropriate distance. Then, choose an eye to test first (left or right). Each eye will be tested independently; this choice is for your convenience.

Calibrate the headset to the testing software by lining up the rectangular slit in the headset to the rectangle present on the screen. Use the headset to cover the eye you are not testing.

To begin the test, press the start button manually or say “start.” Read the letter that you can see on the screen. If the test is not understanding you, saying the word ”letter” before the actual letter helps with recognition.

The test will begin at the weakest vision level (highest optotype row) If all letters in the level are read correctly, the test will move to one level smaller. If a letter is guessed wrong, the number of wrong letters guessed in that size setting will be recorded. If the user guesses 2 letters incorrectly, the test will be terminated

After completing all levels for one eye, it will switch to the opposite eye. After test completion, the test will be terminated.

The visual acuity of the user will then be displayed, along with a brief explanation of the significance of the result. This can be copied for easy reference.
