Mr. 3 told me he couldn’t “see very well” . This was probably because he was upside down, but it gave me the idea to test his vision.
I wrote letters on a piece of paper indifferent colors and sizes. If you have an older child they can help you do this part or make their own chart. If your child is not comfortable with letters, you could try shapes of different colors and sizes.
Next, we hung it on the wall. Then we placed a chair a few feet away. I gauged the distance by when my own poor vision made reading the chart challenging.
He did great. Dr. Mom feels confident in his ability to see.
If you try this at home, let me know how it goes!
