A LOT can happen in a week, but not necessarily to bananas.

Last week I wrote about my excitement after hearing that EnChroma, a firm that makes glasses that ‘alleviate the symptoms of colourblindness’ in people like me, were sending me a pair to try.

They are careful not to claim their glasses are a cure, mainly because people often assume that’s the aim, but I secretly hoped that, for example, I might see the difference between ripe and unripe bananas for the first time.

Well, the glasses arrived, but they made no difference to the bananas, nor most other colours.

But they did have the curious and pretty cool effect of significantly enhancing everything that’s red – a previously dark and inconspicuous colour – yet without making the view seem unnatural, which is quite a feat.

So the phrase ‘as red as a beetroot’ finally makes sense.

Beetroot is normally the darkest of vegetables, with virtually no colour, but in the sunlight, through a pair of EnChroma glasses, it looks positively radioactive.

I also noticed how white-skinned people, who usually look pale and even pallid to me, have suddenly taken on a healthier glow.

Indeed, my special lenses generally make the world a little warmer and less bleached, and although that is a long way from being life-changing, it’s novel, pleasant and fun.

Whether that makes the glasses worth the £210 they would have cost me to buy is another matter.

It should be said that there are many different types and degrees of colourblindness, so the effectiveness of EnChroma’s glasses varies from person to person, and some people have been genuinely bowled over by the difference it makes to them.

So it’s worth a try, and they come with a money-back guarantee.

And as always with colourblindness, there is more to it than meets the eye.

Just as revealing as the limited benefit the glasses gave me was their effect on people with normal colour vision.

My wife has always been desperate to know what she would see if she could look through my eyes, and although the glasses were not designed for her, she hoped to somehow experience the same colour enhancement I got from wearing the glasses.

So you could say that when nothing happened, apart from everything taking on a pinkish hue, she was a little green with envy.

All this tells us something quite profound, I think.

It seems to underline just how much we all crave a change of scenery sometimes, or anything that gives us a new perspective on life – and if we haven’t learnt the value of that during the past year, we never will.

I could write a whole book about colourblindness, and one day I probably will.

And one of the chapters will be about the futility of hoping for a cure.

You learn to live with it, you even grow to like it, and – contrary to what normal-sighted people sometimes imagine – it doesn’t drive you bananas.
