HealthyEyes – your sight is precious to us
What we see doesn’t just depend on our eyes. It also depends on how our brains interpret the images our eyes pick up. What we see is actually our brain’s translation of what it thinks is most likely to be there. This is why we sometimes think we’re seeing one thing when the reality can be quite different - our brains have been tricked.
Optical illusions are one way of tricking the brain, and they show - often in quite startling ways - how what we think we see may not actually be the same as what’s really there at all!
