Home Vision Self-Test
Suspect a vision problem — for yourself or your child? A quick check at home with a Snellen eye chart can point you in the right direction before you visit the practice.
When to screen at home
Try this simple test if you or a family member:
- Squints, frowns or tilts the head when looking at distant objects
- Holds books or phones unusually close to the face
- Struggles to see the school chalkboard or whiteboard
- Complains of frequent headaches or tired eyes
How to use the Snellen chart
Download and print the chart
Print the Snellen chart at 100% size on an A4 page, ideally in good light.
Stand at the correct distance
Follow the distance printed on the chart (typically 3 or 6 metres) and hang the chart at eye level.
Test one eye at a time
Cover one eye with your hand (don't press on it) and read the letters from the top down, noting the smallest line you can read clearly. Repeat with the other eye.
Compare and follow up
If one eye reads noticeably worse than the other — or either eye struggles with the middle lines — book a professional eye test.

From about age 40, most people start needing reading glasses — the eye's lens gradually loses its flexibility. If you find yourself holding reading material further and further away, or struggling to read at the usual 35–40 cm distance, it's a good reason to consult an optometrist.
