If you’ve been looking for something interesting to put into your eyeballs, but don’t know where to start, great news! Science for the Masses, a biohacking group out of California, has devised a method to give people temporary night vision by dripping a chlorophyll-related chemical directly onto the eyes. Mic reports that the substance is a “kind of chlorophyll analog called Chlorin e6 (or Ce6), which is found in some deep-sea fish and is used as an occasional method to treat night blindness.”
