Is it a layover or a change to a new flight? Typically, in any international airport transfer, as long as the two flights are on the same itinerary, the passenger will remain in the international terminal and not be required to go through immigration. In such a case, a transfer visa is not required.
If it's a change to a new flight, a visa (or visa exemption) is required to go through immigration to the main terminal for a new check-in. However, 1 hour and 50 minutes is not enough time to do this in most circumstances.
