Sadly, the day came last Tuesday when K* was prescribed glasses. Last week, the teacher had to move him to the front of the class because he complained he couldn't read the whiteboard.
Both Jenny and I wear glasses so we knew it was very likely at least one or both of our kids would also need glasses. Luckily, R* seems to have escaped so far but I didn't get my first pair until I was about 14. There's still time.
Glasses are a hassle and I don't think you can ever say glasses improve your looks. It's a shame. He's taken it quite well and agrees it very nice to be able to see so much detail in the distance now. At least it should help him at school.
