What if your eyes and brain are changing colour before you even realise it? 👀🧠
This fascinating Harvard illusion uses 9 identical purple dots to show how your:
• fovea (central vision),
• natural yellow eye filters, and
• brain’s visual processing
all influence what you think you see !
As we focus, adapt to light, and process contrast, our visual system constantly “fills in the gaps” — often without us noticing.
During Myopia Awareness Week, it’s a great reminder that vision is more than just seeing clearly on an eye chart. Early eye changes can happen silently, especially in children developing myopia (short-sightedness).
📍Regular eye examinations and axial length monitoring can help detect progression early and protect vision for life.
Have a look at the dots… do the colours seem to shift or glow for you? 💜💙
