Tags: #Medical #Technology

Easee offers the opportunity to test one’s visual function remotely, be it for the purchase of new glasses or as part of a remote eye-care solution. As a company, we are driven to deliver the best quality and experience and one of easee’s core values is transparency. Particularly when it comes to the quality of our products. We, therefore, want to share with you an interesting piece of research on remote vision testing.

Recently, a systematic review was published by the team from the University Medical Center Utrecht. This paper summarized the scientific findings of all independent research papers and tools available to date. Why is this important? Many apps and websites offer online vision tests or visual symptom checkers, though the quality and validity of these tests are seldom evaluated*, nor are they certified for medical use (i.e. CE certified in Europa or FDA approved in the US). 

In this independent investigation, the performance of the online measurement of visual function and conventional clinical charts is shown to be equivalent. This means that you could have your vision safely assessed at home, nursing home, or at school, using applications on smartphones, tablets, and/ or computers. The easee exam performs on par with other validated solutions. Rest assured, the easee test is CE certified and FDA approved for its intended purposes.

Making eye care accessible to everyone


We have 3 short questions before we can get started.

1. The eye-exam takes about 20 minutes from beginning to end. Is now a good time?

● No lost time traveling or waiting for your appointment. The only minutes spent is on the test itself.

Glad to hear you’re not in a hurry. This will improve the results.

Do you have a smartphone, together with a laptop (or tablet), and 3 meters of space at your disposal?

● Your smartphone will function as a remote, and is also used together with a laptop (or tablet) to perform the online eye-exam.

That’s great! We’re almost good to go. Just one more thing.

Do you have your current eyewear prescription at your fingertips?

● Your prescription powers your eyewear. Our optometrists use your old one as areference for validating your new prescription.

Take the exam now, or save it for later?

Based on experience, we advise you to take your time with the online eye-exam to optimize your results. We can email you a link to proceed whenever you’re ready.
