Eyelid Spasms
Your eyelids move uncontrollably, making it difficult to focus. While this is occurring, you need to succeed on a DC 8 + (IE) Constitution check to maintain concentration on spells or to avoid a −(IE) penalty on all ranged attack rolls for the round. Occasionally (Roll (IE) or under on 1d20 each time it happens or every hour if Acute), the spasm causes your eye to close completely for 3d20 minutes, giving disadvantage to Wisdom (Perception) checks on that side for the duration.
