Adaptive optics reveals woman who suffered permanent eye damage from viewing the solar eclipse with fake or low quality Eclipse glasses has solar retinopathy, with a microscopic-sized crescent shaped area of damage "burned" into her retina. Doctors are describing it as a projection of the crescent of brightness when the eclipse was approaching totality in her viewing area and the sun was almost totally eclipsed, appearing as a bright crescent in the sky. Woman's vision is degraded with what she perceives as a crescent-shaped dark spot in the center of her field of vision.
