One of the most common concerns about our project to extend human vision into the near infrared goes something like this:
If you’re going to see infrared light, won’t the heat from blood vessels in your eyes prevent you from seeing anything with any clarity at all?
In short, the answer is no. This is a common misconception created by such pop culture phenomena as the Predator film franchise and perpetuated by poorly written popsci articles which use the term “infrared” as a blanket category for any radiant energy longer than 700nm without specifying exactly what range of the radiant spectrum is being discussed.
