My eyes have deteriorated to the point where i have to have an operation to remove cataracts. I’m writing now before the operation. I’m told by the surgeon and everybody else not to worry and my eyesight will be considerably improved. One of the effects will apparently be a shift (mostly temporary), towards blue. I will try and document it. I’ll stay off the operation itseif – too full of the usual medical mendacities such as, “This may be a bit uncomfortable”.
Of course one of the problems with doing this is that I will only see with the new vision so comparing before and after subjectively is not easy if at all possible. furthermore, the operation is in two stages, one for each eye. Anyway. I’ll have a go. Below left is a photo of one of my paintings as seen from my left eye (The new one) and from the still-cararacted one, as near as I can get to true colours on my monitor. (The arcana of colour profiles is beyond me).
Or the corner of my studio
Over the month between operations the difference diminished but the second operation brought about a similar remarkable shift to violet.
Now everything has settled down and the colour seems “normal” I don’t need glasses except for reading and there is a lot more light around.
