Exposure to the sun with existing light sensitivity
 

I currently have the symptom of light sensitivity. I usually wear dark sunglasses around brighter lights and the sun but today the sun shone unexpectedly in my eyes for 10-15 seconds. It hurt my eyes and caused them to tear up a little.

Does anyone know if this type of exposure can damage the brain similar to another hit to the head? I am concerned that I will have worse light sensitivity and worsening cognitive symptoms as a result of today's mishap. I'm just trying to gauge what kind of setback to expect from this.


Thanks

No, it does not cause damage. Light sensitivity is due to the brain not filtering out the glare and not causing the pupils to constrict fast enough. It is uncomfortable but not damaging.

Just more anxiety.

Haven't had any relapse as a result of this so it seems a little exposure isn't harmful. I would imagine overstimulation from light could be a problem though.
