Blindspot

Almost hit someone turned onto a street.  She was crossing the street.  Emi says, dont hit that lady! And thats when I first see her. Again, it was about 45° on left side.  I wonder if I have a blindspot there, though I dont notice anythin odd in my vision on that side.  At first, I thought it was a result of my stroke.  But just read that from age 41-60 that people start having vision decline so the stroke was just a coincidence?  I dunno if this is somethin that can be corrected with glasses.  Makes driving that much more scary.  Dont want to accidentally hurt someone or get into another accident just because I didnt see them.  Might go get another eye exam, its been over 2 years.
