Visual Stress Testing
Visual stress is a condition that affects reading ability and can cause headaches, eye strain, and fatigue. It's often undiagnosed because standard eye tests don't screen for it. Family Eyecare is one of the few practices in the Harrow area offering specialist visual stress testing using Mearles-Irlen screening.
What is Visual Stress?
Visual stress occurs when the brain struggles to process visual patterns, particularly text on a page. It can affect both children and adults, and is far more common than most people realise. Many people live with visual stress without knowing, assuming that everyone experiences reading the same way they do.
The condition is separate from standard sight problems — you can have perfect vision on a standard eye test but still suffer from visual stress. This is why specialist screening is so important.
Common Symptoms
How We Test for Visual Stress
Our Mearles-Irlen screening uses a systematic approach to identify visual stress and find the right solution.
Coloured Overlay Assessment
We test a range of coloured overlays placed over text to determine which colour, if any, reduces your visual stress symptoms and improves reading comfort.
Rate of Reading Tests
Using standardised tests, we measure your reading speed and accuracy with and without overlays to objectively assess the benefit.
Precision Tinted Lenses
If overlays help, we can assess you for precision tinted lenses — the exact tint is built into your regular glasses so you benefit all the time, not just when reading.
Do these symptoms sound familiar? A visual stress test could make a real difference. We're one of the few practices in Harrow offering this specialist service.
Who Should Be Tested?
Children
Children who struggle with reading at school, avoid reading, or complain that the words move. Visual stress is often picked up as a learning difficulty when the solution may be simpler.
Adults
Adults who find reading tiring, get headaches or migraines after screen work, or have always felt that reading takes more effort than it should.
Dyslexia Diagnosis
Anyone previously diagnosed with dyslexia should consider testing. Visual stress is sometimes misdiagnosed as dyslexia, and even where dyslexia is present, treating visual stress can significantly improve reading comfort.
How We Can Help
If visual stress is identified, the good news is that it can be managed effectively. The two main options are:
Coloured Overlays
A simple, affordable starting point. A precisely chosen coloured overlay is placed over reading material to reduce visual stress. This is often tried first, particularly with children, to confirm the benefit before progressing to tinted lenses.
Precision Tinted Lenses
For a more permanent solution, precision tinted lenses are built into your regular glasses. The exact tint is calibrated to your individual needs, meaning you benefit from reduced visual stress throughout the day — not just when reading with an overlay.
