The easee CO2 calculator

Tags: #Human

At easee, we are committed to make everyday count and build a better future. A future with accessible eyecare for everyone. Making eyecare more accessible is good news for all who are interested in preventing poorsightedness. But there is more. Delivering eye care remotely saves you a trip to the store or to the clinic! Please read below how we at easee work on reducing your carbon footprint with technology (spoiler alert: lot’s of numbers…) and how you can calculate the impact of a digital transition in your business or clinic.

Healthcare is big and accounts for an estimated 4‐10% of total global carbon dioxide (CO2) emissions. Reducing the climate impact in healthcare contributes to achieving the global sustainability goal of carbon emission reduction. Note that many people in society need eyecare: think of glasses, contacts, cataract surgery, occupational health screenings, etc. Travel‐related emissions contribute roughly 20% to the total healthcare-related emissions. These emissions increase yearly also due to increased health care consumption in general.

As mentioned above, telemedicine is an interesting avenue to substantially reduce carbon emissions in healthcare. The COVID‐19 pandemic was a huge accelerator for the expansion of remote digital care. Avoiding a substantial part of patient travel was shown to be possible and good practice examples emerged.

Better accessibility to care through telemedicine increases patient autonomy, provides an alternative to costly patient travel, and is thought to decrease our global carbon footprint. How significant this carbon reduction is for climate change is unclear, and therefore our research team pursued a systematic review of the existing sources and peer-reviewed literature. This led to a comprehensive method to evaluate the environmental impact of telemedicine compared to usual care. And to aid the general public, we conceptualized the Digital Transition Carbon Calculator (DTCC) We consider this tooling essential to raise awareness of its role in reducing overall emissions. The science behind the calculator can be found in this preprint publication.

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.

    If you want to do it right now or maybe you are just curious, no problem.


    Great, you’re all set!
    Let’s get started
