When a Dad took his 4-year-old to the optometrist to pick up new glasses, the boy asked why he had to wear them. The doctor replied, “They’re to help you read and be able to see the computer better.”

When the two of them got back home, the boy sat down at the computer. In a few minutes he called his Dad over and said, “There’s something wrong with my glasses.”

“What’s the problem?”

“I can see the computer better, but I still can’t read.”
