Hi!
I'm part of a team doing an engineering project to design a device to detect eye blinking while a patient in the hospital is sleeping.
We have tried to use TCRT5000 sensor (http://www.vishay.com/docs/83760/tcrt5000.pdf) in the prototype and it works like charm ! However, since the TCRT5000 sensor has an IR emmitter we have some safety concerns regarding the IR exposure of the eyelids (mainly, since the eyes are closed) and the eye itself when he/she blinks.
Consequenty, we would need the following information (underlined in yellow) that we couldn't find in the factsheet:

Moreover, it has to be considered that the patients will be exposed to it 8h/day for their lifetime. If you know a way to low the intensity/power of the IR emitter it would be also apreciated. All the information is provided about the sensor is provided in the link above.
