Irlen Screening
Could visual processing stress be making reading harder than it needs to be?
An Irlen screening is a gentle, educational step to explore whether the way your brain processes light may be affecting reading, comfort, and focus, for you or your child.
What it is
What is Irlen / visual stress?
Irlen Syndrome, also known as visual stress or Scotopic Sensitivity Syndrome, is understood as a difference in how the brain processes visual information, particularly certain wavelengths of light. It is not a problem with the health of the eyes, and a standard eye exam typically comes back clear.
When the brain works harder to process what it sees, reading and concentration can become uncomfortable or tiring. Some people notice print that appears to move, blur, or run together; others mainly feel headaches, fatigue, or light sensitivity.
For some people, viewing print through a specific color, using overlays or tints, appears to ease this strain. An Irlen screening explores whether that may be the case.
The role of colored overlays
Colored overlays are transparent colored sheets placed over a page or screen. By changing how light reaches the brain, the right color may reduce visual distortions and improve comfort, clarity, and sustained attention for some readers.
Whether overlays help, and which color, is individual. That’s exactly what an Irlen screening helps explore.
Common signs
Signs people often notice
You don’t need to have all of these. Even a few, especially if reading has always felt harder than it “should”, can be worth exploring.
- Headaches or eye strain during or after reading
- Words that move, blur, double, or run together
- White pages or bright screens feeling uncomfortable
- Sensitivity to glare and fluorescent or bright light
- Losing your place, skipping lines, or re-reading often
- Reading slowly or tiring quickly
- Difficulty with focus and concentration while reading
- Trouble with depth, busy patterns, or judging distance
- Avoiding reading, or saying it’s “boring” or “too hard”
- Fatigue, restlessness, or frustration with close work
Who an Irlen screening may help
An Irlen screening may be worth exploring if…
You’re an adult
who finds reading tiring or uncomfortable, feels sensitive to light, or has never quite understood why focus and comfort don’t come easily.
You’re a parent
of a child who struggles or avoids reading, and you feel something is being missed despite their effort and ability.
You’re exploring
ADHD, dyslexia, or reading and concentration challenges and want to understand whether visual stress is one piece of the puzzle.
An Irlen screening is one area to explore, not a replacement for medical, psychological, educational, or vision evaluation, and not a medical diagnosis of any condition.
The process
What happens during an Irlen screening
An Irlen screening is a calm, step-by-step process. When you reach out, Miranda’s team will explain the options available to you based on your location and needs.
Reach out by email
You share a little about your concerns through the Irlen screening inquiry form. Miranda’s team follows up by email to explain next steps and answer questions.
The screening session
Miranda guides you through a series of reading and visual tasks to look for signs of visual stress and to explore which color, if any, improves comfort and clarity.
Exploring color
If helpful, you try colored overlays to gauge whether a particular color reduces distortion and makes reading feel easier and more comfortable.
Personalized next-step guidance
Miranda shares what the screening suggested in clear language, along with practical, individualized recommendations and whether a separate lens assessment may be worth exploring.
Screening and lenses are separate services
The initial screening explores visual stress and colored overlays. An Irlen lens assessment is a separate service that evaluates individualized tints for Irlen Spectral Filters. A certified Irlen Screener can provide the initial screening; a certified Irlen Diagnostician, such as Miranda, can provide both services.

What results can and cannot tell you
An Irlen screening may help
- Identify signs that visual processing stress could be present

- Give language and direction for further evaluation if needed

- Diagnose dyslexia, ADHD, autism, anxiety, or any medical condition
- Replace medical, psychological, educational, or eye-health evaluation
- Guarantee results: individual experiences vary
- Provide treatment or a cure for any condition
After your diagnosis
What comes next
Depending on what the screening suggests, next steps might include using colored overlays for reading, exploring a separate Irlen lens assessment, or following up with other professionals for areas outside the scope of an Irlen screening. Miranda will help you understand your options without pressure.
Because brain health is bigger than reading alone, some people also choose to explore broader brain health support.
For parents
If your child struggles with reading or school, you know your child best. An Irlen screening can help you explore one possible piece, visual stress, while you continue working with teachers, your pediatrician, and other specialists. It’s a way to feel proactive, not to replace the support already in place.
For adults
Many adults have spent years assuming reading is “just hard” for them. An Irlen screening offers a calm, judgment-free way to explore whether visual comfort can be improved.
Questions
Irlen Screening FAQ
No. An Irlen screening is an educational exploration of visual processing stress. It is not a medical exam, vision exam, or medical diagnosis, and it doesn’t replace seeing your doctor, optometrist, or other professionals.
No. An Irlen screening does not medically diagnose dyslexia, ADHD, or any condition. Visual stress can sometimes overlap with reading and attention challenges, so an Irlen screening explores that one area. It doesn’t replace evaluation by qualified professionals.
No. Some people notice a meaningful difference with the right color; others don’t. Individual experiences vary, which is exactly why an Irlen screening is exploratory rather than a guarantee.
An Irlen screening generally works best once a child can engage with reading-related tasks. Miranda’s team can advise based on your child’s age and situation when you reach out.
