Last week I had temporary blindness. This week blood vessels have been bursting in my eye. Today I went to the eye doctor. To examine the retina drops are inserted, to make the pupil dilate. The eye doctor found a hole in my retina (!) but assures me the bleeding is most likely caused by dehydrated corneas. My nose is always stuck in a book and we blink less when we read (blinking keeps your eye moist).
He says I must read less and blink more. And if anything else bursts in my eye, he will have my head examined.
Here endth the biology lesson.
