You never know how most of the mfgrs will treat damaged optics. Some say up front what they will do (Leupold). I dropped a pack from an elevated blind a few years back. In the bottom was my Nikon binos. The broke in half. Figured my fault, I guess I need to buy a new pair. A friend told me send them in, it will only cost you the postage. I sent them to Nikon and about a month later I got a brand new pair and a letter thanking me for buying Nikon.
Send them back, I am sure they will send an estimate and then you can decide.
