"I need to wait until my child can read before they can have their sight tested"
"Children don’t need to be able to read words, or even letters, in order to be able to have a sight test. Optometrists can use other methods, such as pictures, to check how well your child can see.
As part of a sight test, optometrists also check that a child’s eyes are healthy, and whether they need spectacles or contact lenses to help them see.
Many eye problems can be treated more eﬀectively if picked up early, so we recommend that all children visit their optometrist for a sight test around the age of three."
