I work in an optical store and one thing that has crossed my mind is the definition of normal.
Today in particular a family came in and the son, early teenage years, needed glasses. He obviously wasn’t too keen on getting glasses.
His mum explained to him that what he sees as normal is not what other people see as normal. She recounted her own experiences on getting glasses and the difference it made. Before glasses, she wasn’t aware that she was short-sighted. She thought everyone saw the trees and grass the way she does. But after glasses, she was able to see individual leaves on the trees and each blade of grass.
This wasn’t something I thought a lot about because I have had 20/20 vision for most of my life and recently I was told I was long-sighted. That didn’t make much difference because I can see far and near regardless, I just need extra help with near vision to avoid my eye muscles tiring out and causing big headaches.
This is also the case with colour vision. A friend of mine recently found out he had a colour vision defect. This wasn’t brought to his attention until recently because he thought how he sees colour is how everyone else sees colour. He bought tinted glasses specifically for colour vision defects and was amazed by how vivid the colours appear. They seemed to “pop”. Watching him do colour vision tests is actually amazing and mind-boggling to see.
What is your perspective of the definition of “normal”?
