This happens after a bright flash or by looking at a bright light by mistake. This has never happened until about a year ago. Update: The light is not like the blurred light you see after looking at a bright light. It is a semi-circular jagged line to the right which caused a loss of vision where it exists. It gradually expands and drifts to the right periphery disappearing after about 15 minutes. Update 2: Thanks - I don't know who is giving the thumbs down as all the answers are helpful!
Distorted Vision. Distortion of vision refers to straight lines not appearing straight, but instead bent, crooked, or wavy. Usually this is caused by distortion of the retina itself. This distortion can herald a loss of vision in macular degeneration, so anyone with distorted vision should seek medical attention by an ophthalmologist promptly. Other conditions leading to swelling of the retina can cause this distortion, such as Macular edema and Central serous Chorioretinopathy. An Amsler grid can be supplied by an ophthalmologist so that the vision can be monitored for distortion in people who may be predisposed to this problem.
