As a parent, navigating the various learning difficulties your child might face can be challenging. Two conditions that often cause confusion are visual stress and dyslexia. While they can sometimes co-occur, they are distinct issues with different causes and treatments.
What is Visual Stress?
Visual stress is a perceptual processing issue that affects how the brain interprets visual information. It is not an optical problem but rather a neurological one. Symptoms can vary widely but often include:
· Headaches and eye strain
· Blurring or movement of print
· Letters changing size or shape
· Illusions of colour on the page
· Sensitivity to bright light
· Difficulty judging distances and spatial awareness
Children with visual stress may also exhibit behaviours such as moving closer to or further from the page, using a finger as a marker, or becoming restless while reading.
What is Dyslexia?
Dyslexia is a language-based learning difficulty that primarily affects reading and spelling. It involves difficulties with phonological processing, verbal memory, and verbal processing speed. Unlike visual stress, dyslexia is not related to vision but to how the brain processes language. Common symptoms include:
· Difficulty sounding out words
· Problems recognising common words
· Trouble with spelling and writing
· Challenges in isolating sounds, matching sounds to letters, or blending sounds into words
Dyslexia can also impact other areas, such as writing and speaking, making it a broader issue than visual stress.
How Do They Differ?
Co-occurrence of Visual Stress and Dyslexia
It is not uncommon for children to experience both visual stress and dyslexia. Studies suggest that around 20% of people with dyslexia also suffer from visual stress, although the conditions are separate. When both conditions are present, addressing visual stress can sometimes alleviate some of the reading difficulties, making it easier to focus on interventions for dyslexia.
Identifying and Managing Visual Stress
If you suspect your child has visual stress, a thorough assessment by an optometrist or orthoptist is essential. They can conduct tests to rule out other visual issues and recommend treatments such as coloured overlays or tinted lenses. These aids can significantly reduce symptoms and make reading more comfortable.
Supporting a Child with Dyslexia
Dyslexia often requires a multidisciplinary approach. This can include specialised phonics teaching, one-on-one tutoring, and the use of technology to aid learning.
Conclusion
Understanding the differences between visual stress and dyslexia is crucial for providing the proper support for your child. While these conditions can sometimes co-occur, they require different approaches to treatment and management. Early identification and intervention can make a significant difference in your child's learning journey, helping them to achieve their full potential.
