Identifying Undiagnosed Vision Or Hearing Impairments In Children

Identifying Undiagnosed Vision Or Hearing Impairments In Children. Hello everyone, I hope you are well. In today’s post, I will be sharing a guest post from Michael Ter-Berg, CEO of Thomson Screening. Michael will explore how unidentified vision or hearing impairments can hold students back and what schools can do about it. It is now thought that a large percentage of ‘learning difficulties’ could be due to hearing and/or vision impairments. According to the Cooper Institute, 60% of ‘problem learners’ may have vision problems. Additionally, several studies show that up to 40% of students who have been diagnosed with a learning disability can have an undiagnosed visual impairment.

Identifying Undiagnosed Vision Or Hearing Impairments In Children

While you might think identifying children with poor vision or Hearing is a public health issue, the impact is often on children’s education. Research suggests that a notable proportion of what is commonly categorised as ‘learning difficulties’ might stem from undetected hearing or vision impairments. According to findings from the Cooper Institute, a remarkable 60% of individuals identified as ‘problem learners’ could be contending with vision issues. Additionally, studies indicate that as much as 40% of students diagnosed with learning disabilities may have undiagnosed visual impairments.

Equally important are hearing impairments, which should not be disregarded. These conditions have been linked to attention difficulties, diminished academic performance, and behavioural challenges, particularly among boys. The frustration and monotony of hearing difficulties can hinder a child’s overall well-being and academic achievements.

Impact Of Undiagnosed Hearing Or Vision Issues

Unidentified hearing and vision issues can often be quickly addressed or corrected. For instance, a study by UCLA revealed that a significant proportion (80-90%) of vision problems can be rectified with eyeglasses. However, schools cannot implement timely and cost-effective interventions without identifying which children are affected. Children experiencing hearing and vision difficulties face a higher likelihood of falling short of Key Stage 2 (KS2) targets than their peers without impairments, leading to lower overall grades at the GCSE level. Consequently, their opportunities for advancing to further education may diminish, negatively influencing their self-esteem and future career prospects.

The NHS conducts vision and screening only at the Reception age, and coverage can be patchy. Far fewer areas screen for Hearing. For vision, the main target is just one condition, lazy eye (amblyopia), whereas other conditions, especially short-sightedness (myopia) and colour blindness, can affect learning outcomes. Hearing and Vision changes can occur naturally over time as children grow. Other causes of change include prolonged exposure to excessive sound or time in front of computer screens.

Screen Time

One significant consequence of the pandemic has been the surge in screen time for leisure and online learning; there has been a sharp increase in childhood short-sightedness as children spend less time outside and more time in front of laptops. Over a relatively short period, myopia has increased by 250%. Parents and educators should be attentive to signs of discomfort and decreased visual acuity in children, as these may indicate underlying vision problems.

Around 8% of boys and 2% of girls have a colour vision impairment. Colour vision is not part of NHS vision screening programmes because there is no treatment. However, with the knowledge of which children have a colour vision impairment, schools can make straightforward and effective adjustments. But schools need the data. The same goes for other undetected vision and hearing conditions.

Checking Children For Vision And Hearing

With software like SchoolScreener for Schools, it is swift and easy for schools to check children’s Hearing and vision. No clinical knowledge is needed, enabling SEN or Support Staff to conduct quick checks after less than 30 minutes of online training. Schools also automatically receive the data to plan and support children appropriately. Parents also receive a report suggesting, if necessary, that they take their child for further assessment – for vision to a high street optician and for hearing to their GP. A full assessment from High Street opticians is free, as are glasses for 5–16-year-olds. The SchoolScreener for Schools software is a variant of SchoolScreener used in the NHS to screen children at Reception in over 5,000 schools.

Alternatively, software providers (such as Thomson Screening and developers of SchoolScreener) can supply DBS/Enhanced Disclosure-compliant staff to carry out checks at KS2 and KS3 on the school’s behalf.

The Benefits Of Reports For Schools

Implementing a program of regular checks during Key Stages 2 and 3 equips schools with the knowledge and data to make informed decisions. This approach allows schools to better plan resources, save costs, and make necessary adjustments to support their students during the later stages of Primary and Early Secondary schooling. In essence, data becomes a powerful tool for schools to enhance the educational experience for every child.

I hope you enjoyed that.

    There is a saying that it is better than early than late.
    Early diagnosis is better for easy medication and corrections, while late diagnosis might result in a long medication or the worst.

    This is information that will be useful to many parents to help their children lead more meaningful lives. I was nearsighted in grade school but didn’t know it. Once my parents figured that out and I got glasses, my life improved.

    Every parent out there needs to bookmark this post! My son had vision issues, and we never knew. We finally figured out something was wrong because his grades began to slip.

    Catching vision or hearing impairments early is so important! Young children learn by absorbing the world around them. They can’t do that if their interaction with it is inhibited.


    Your post about identifying undiagnosed vision or hearing impairments in children is an important and informative resource for parents and caregivers. The signs, symptoms, and guidance you provide are essential for early detection and intervention. Thanks for shedding light on this crucial aspect of child health – it’s a valuable read for those concerned about the well-being of children’s sensory development. Keep up the great work in providing information that can make a difference in children’s lives! 👦👧👁️👂🌟
