Four days ago, I got up in the morning and saw a big black spot of irregular shape, roughly half an inch wide, through my right eye. It's fixed in space, unlike one of those tiny floaters I notice once in a while. About five minutes later, it's gone. So I went in to see my eye doctor today. He thought that what I had was most likely an ocular migraine, not something of major concern; but he did find the pressure in my right eye too high and see signs of glaucoma. I am now using an eyedrop to control the high pressure which can cause blindness if unchecked. I see that the Lord gave me the migraine sign to get me to see the doctor. Otherwise I might not go visit one for another few years. So I just want to thank the Lord for his ever present mercy, our greatest treasure. We only need to recognize it.
