Photosensitivity

You are sensitive to bright light such as sunlight, including all but the darkest cloudy days. While in moderate to bright light, you have a −(IE) penalty on attack rolls, as well as on Wisdom (Perception) checks that rely on sight. In dim light, you can see as if in daylight.
Real-world Examples
Photophobia, Visual Snow Syndrome
Assistive Options
This sensitivity is especially affected by the blue and ultraviolet (UV) end of the spectrum, so spectacles with yellow lenses can reduce the IE by 2 but cause Colorblindness while worn. Alternately, sunglasses reduce the IE by 1 without the Colorblindness side effect.
