It's a good question, but it seems unlikely to be feasible given that "a well-lit office or classroom is usually no more than 500 lux."
I have a hard time believing that it's 20 times brighter outside than inside, but then again I have no issues seeing my phone's or laptop's screen indoors, while it's almost impossible outside (even in the shade) to see anything.
