782 is near the minimum with eye injuries
The title of A series of 777 pellet gun ocular injuries over a 4-month period in Kashmir is pretty self-explanatory. The authors reviewed records from 777 patients with injuries from taking a pellet to the eye from a "tertiary hospital in Srinagar, India, between July and November 2016" (a smaller subset of the timeframe the claim in question covers). As the "Limitations" section says, this number does not include people who went to other hospitals or did not seek any medical treatment.
Note: We can't conclude that the shots were aimed at the eyes specifically from this because these guns "propel hundreds of small metal pellets, or birdshot, capable of piercing the body and eye", all in a single scattering shot. The eyes are the most vulnerable, but there are plenty of other injuries from these guns reported on other areas of the body.
