I've always had "perfect" vision, but noticed the last year or two that I was getting more frequent headaches and tired eyes, so I finally bit the bullet and went to an optometrist.
When Dr. Dagron asked how I found his office I told him, "I pulled up Google Maps and it was two blocks from work so here I am!" He stared at me for a moment and replied flatly, "Well that's a terrible way to find a doctor. You're lucky you found a good one." And he was right! The office staff are very friendly and helpful, and Dr. Dagron made my first ever optometrist visit a great one.
