Narrative:
I was climbing out of FL360 for FL410 and my first officer started feeling light headed and a sense of numbness. About 10 seconds after that I felt very light headed and started getting tunnel vision so I knew something was wrong with the pressurization. I then put on my oxygen mask and started an emergency descent and declared an emergency. ATC vectored me to the closest airport and I made a safe descent to landing and no one was injured nor was the airplane harmed. After getting on the ground the passenger also complained of being light-headed and getting a headache while climbing out.
