I Am A Generally Healthy 61 Year Old Male. While

I am a generally healthy 61 year old male. While cooking just now I was experiencing dizziness & Blurred vision. The blurred vision occurred on the outside periphery of my eyes and was a little like looking through water. It lasted for 3 or 4 minutes and forced me to sit down to not lose my balance. My heart rate didn't appear to be abnormal nor did I exhibit any of the symptoms of a stroke which I looked up on the internet. I would appreciate any suggestion.
