I am a 28 year old woman and I wear glasses due to long and short sighted issues. I have always worn glasses since I was in primary school. I regularly get my eyes tested. Nothing serious has come up. Dimming lights to which I associated with electrical issues, is happening all the time. Only recently I've started to question what it is as no one seems to notice or react to it. Is there something medical that can explain this happening. There is no other symptoms.
