Narrative:

We were cruising at FL320 with the first officer as the PF. Just prior to the normal descent point the right oil strainer clogging light illuminated. We accomplished the QRH procedure. With all other engine parameters normal; per the QRH procedure; I decided not to shut down the right engine and operated the engine at idle for the remainder of the flight. I elected to continue to ZZZZ since ZZZZ1 and ZZZZ2 were approximately the same distance as our destination; and I was very familiar with ZZZZ; I declared an emergency and briefed the flight attendants. We then accomplished the 1 engine landing procedure and normal checklists. With the right engine at idle the first officer flew the visual approach to runway xx and made a normal landing.
