Sorry, no medical questions on this subreddit. We are just not qualified to answer them and I would hate to risk you being misinformed. You are welcome to repost with any other questions you may have.

Oh I'm sorry, I didn't realise. Feel free to delete my thread.

Visual Acuity 6/15 is the metric system for 20/20 imperial system for standard vision measurement. A chart used is the Snellen Eye Chart. It means his vision is 20/50 and using pinhole it's 20/40. In layman's terms, if you can see an object clearly that is 50 feet away, your son needs to stand 20 feet away to see the same object. For example, my vision is 20/400.
For the other items, it's better if you speak with a medical professional like a family doctor, who can explain what those medical terms mean.

That's really helpful, thanks. So that bit is about how far he can see.

Yeah. Visual Acuity is how far someone can see. Depending on the assessment there various system of measurement. So far I have noticed 3 systems, 20/20 where the distance is in feet and the 6/6 or 3/3 are in meters.
