Can you read in the full moon light?

Moonlight is with only 1 lux brightness a thousand times weaker than the sun light with more than 100,000 lux. Nevertheless, you sometimes get the feeling that it is so bright in the full moon that you should be able to read. We would like to give this a try and invite all full moon friends to start on a small reading test in the full moon light and to report back the results.

Reading test 1: newspaper/book
Simply take a newspaper or a book and step outside to a spot where there is no artificial light within close proximity (like street lights, window, car head lights etc.). Best, if you take a little walk in nature. Amid the full moon light, wait until your eyes have adjusted to the darkness and then try reading the text. Begin with the headlines and then try the regular text. Make sure, whether the text is easy to read or if you partly have to guess or are not able to decipher anything at all.

Reading test 2: sheet with font sizes
Because the font sizes are not comparable in different newspapers and books, we are offering you this sheet as PDF, which contains text in different sizes. You can download and print this file and right away begin with the reading test in the full moon light. Please indicate below the smallest font size that you were able to read.

We look forward to finding out the results, because in several researches – also from NASA – it has always been concluded that most people cannot read in the moon light. We will see.

We are looking forward to your experiences and comments!
