Artificial Eyes and Light Perception – The Mystery

When someone has lost an eye, the ability to perceive light has also gone. Without the retina, cornea, rods and cones – the integral structures within the eye that detect and send images to the brain for interpretation – there is no way a person can see, let alone be aware of the light.

Or is there?

We’ve had some very interesting feedback from a small number of our clients about being affected by bright light. In particular, glare from the sun is a problem for them. You might be amazed to learn that two of these people have bilateral eye loss and so have a pair of artificial eyes. Another person has one artificial eye and finds that she has to close that eye when looking upwards because of the dazzling glare. This phenomenon isn’t just an effect of the sun as the glare is also detected in a bright room. 

As far as we know, there is no scientific explanation for why this occurs. And we know it doesn’t happen for everyone with either bilateral or unilateral eye loss.

If you also suffer from the glare or bright light, we’d love to hear about it. Has anyone come across a medical explanation for this phenomenon?

Funny thing is that so many people would ask, “Can you see in that eye OK now?”
