Get their eyes checked in case they have them that close because they need to?
Amen to this. Jeez, just get them checked.
We took ours to Specsavers as the test was free. The school checks are essentially can they see a ball thrown at their face and not much else.
Specsavers did assess our children's conditions well. One was fine, the other really needed glasses.
Specsavers then couldn't work out how to treat that, and prescribed way too harsh a prescription.
A bit like having a wheel alignment test, being told it's out and needs adjustment, and then having no idea how to resolve it, and in our case yanking the wheels way too far the other way around.
We then went to a real optometrist, who came to the same diagnosis as before, but prescribed something roughly half the strength, and everything is great now.
