Eye...Eye..!

My dad used to be an optician. I couldn't bring myself to get rid of all his old equipment so we keep his eye testing chart in the living room and use it as a light.

I was never quite sure what the correct answer is when the optician asks you which ones seem clearer/brighter.

They seem different to me every time a look at them. Obviously different answers correspond with your eye condition but that must mean that mine are in a constant state of flux!
