“How are Irlen lens colours chosen? Can my child just pick their favourite colour?”
Great question — and one we hear often!
Irlen lens colours aren’t chosen based on personal preference. Your child can’t simply pick their favourite colour, and they also can’t avoid a colour they don’t like.
That’s because Irlen colours are prescribed, not chosen like regular tinted glasses.
During the Irlen assessment, we spend around 2 hours carefully determining the exact colour that calms your child’s visual system and reduces symptoms. This involves:
👁️ Looking at how different colours affect their comfort
🔡 Testing how letters appear on an eye chart
📖 Checking for distortions, glare, and reading ease
🧠 Observing how their brain responds to different wavelengths of light
The right colour is the one that brings clarity, comfort, and stability—even if it isn’t a colour they would pick themselves.
So no, it’s not about favourite colours.
It’s about finding the precise filter their brain needs to function at its best.
