There are only a few days left in October, but there's still plenty of time to make a major impact: through the end of the month, Horizon will donate $1 to Prevent Blindness every time someone texts EYE to 56512, up to $10,000. Sending off a quick text is an easy, effective way to keep up the spirit of World Sight Day through the end of October, and to hopefully help change lives all around the world.
