Blue Calcite and/or Garnet
I was just reading about Blue Calcite. Judy Hall says one of the benefits of this crystal is to help with cataracts and other non-inflammatory eye issues. She also mentioned that Garnet can help stimulate the eyes.
Per author Robert Simmons, he mentions Blue Apaptite, Celestite, Gaia Stone, Herkimer Diamond, Iolite, Onyx, Rhodizite, Blue Sapphire, Blue Scapolite and Ulexite crystals afflicted with eyes. I'm not sure exactly how as didn't read into all of these crystals, but hope that gives you a direction in your own search.
