Migraine: Your symptoms sound representative of a migrainous event. The aura that you describe as a "zig-zag" light with partial blockage of vision is very classic. Bright lights directed at your eyes can elicit such symptoms in some people. Some people will also have headache or nausea/vomiting that follow the aura. If these are particularly frequent & bothersome, your family MD may be able to help you.
