Why do screens or monitors seem more intense when ADHD is present?

Many people with ADHD describe screens as “too bright,” “too sharp,” or simply overwhelming. According to NHS sensory guidance and recent neuroscience research, ADHD can heighten sensitivity to brightness, contrast, flicker and digital movement, all of which are amplified on modern screens.

Why screens feel more intense 

Studies show that ADHD is linked to reduced visual filtering and increased sensory responsiveness. Research examining visual processing differences in ADHD, such as this meta-analysis of visual function, indicates that people with ADHD are more sensitive to glare, brightness and contrast changes. 

Further research on sensory processing and ADHD shows heightened activation in the visual cortex during screen tasks, meaning the brain must work harder to organise what it sees. This extra neural effort often leads to visual fatigue, headaches and difficulty sustaining attention. 

Some ADHD brains also respond more strongly to flicker or rapid scene changes, as highlighted in studies of visual strain and dark mode benefits. Blue light may add to discomfort for some individuals, although evidence on blue-light filtering is mixed, as shown in recent systematic reviews. 

What can help? 

Adjust brightness and colour 

NHS and occupational therapy teams recommend lowering screen brightness, choosing warm colour temperatures and using anti-glare or matte displays. These recommendations are reinforced in the SASC visual difficulties guidance. 

Reduce glare 

Position your screen so it avoids reflections from windows or overhead lights. The NHS England sensory-friendly resource pack also suggests blinds, soft lighting and diffused desk lamps. 

Use warm-tone modes and dark mode 

Warm filters can reduce visual intensity, and some people find dark mode more comfortable, supported by research on screen mode and visual fatigue. 

Consider blue-light filters (with realistic expectations) 

Blue-light coatings and digital “night modes” are safe to try, but reviews such as this blue-light filter study suggest benefits vary between individuals. 

Take structured visual breaks 

OT guidance, including advice from NHS-run ADHD sensory services, recommends the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. 

Adapt your workstation 

Helpful adjustments include correct screen distance, ergonomic height, and using anti-glare hoods or filters. NHS occupational therapy resources such as the SLAM ADHD sensory needs guide outline these recommendations clearly. 

A takeaway 

If screens feel “too much” when you have ADHD, it isn’t imagined; your brain may process visual information differently, making digital environments more intense. Small changes in brightness, colour, layout, and lighting can reduce strain and help you stay more comfortable and focused.
