Cataracts and Painters

I was researching painters this afternoon who had cataracts.
Claude Monet was one. He was about 20 years with his cataracts and would not have him done because of Mary Cassatt who also had cataracts and had several operations and went blind in the end. That was sad. I did not know that. But when Monet finally had his cataracts done he had some vision restored. Prior to having the cataracts done there was a lot of oranges and yellows in his paintings. But after he had his cataracts done he didn't like them anymore , destroyed most of them, and was painting more in blues, cooler tints.

The reason I was researching this was because of realising my left eye, the good eye sees in warmer tints, and my new cataract eye sees in more cooler tints, quite blue in fact. And now the two eyes are merging to see just in blue tints and I am noticing this over the progression of today, just in one day.

I was sitting on the swing and it was just getting dark because I was changing the SD cards in the trail cameras. And I was looking at some of the vegetation, and I realised the leaves were in incredible detail.

I have only got a monofocal intraocular lens (IOL), And I was led to understand that this was just distance and middle distance. And that I would need reading glasses. But I don't, I can see to read without glasses. I did some research on that, and I came up with these possible explanations...

"Depth of Focus: Some monofocal lenses have an extended depth of focus, meaning they provide more range of vision than a standard monofocal. Even if your IOL isn’t officially classified as an extended-depth IOL, it may still offer a wider range of clarity than expected.

Pupil Size: If your pupil is small in normal lighting conditions, it can increase your depth of focus, making both near and distant objects appear clearer than they would with a larger pupil.

Brain Adaptation: The brain is excellent at neuro-adapting to new vision. Over time, it learns to maximize what the new lens provides, sometimes allowing for sharper focus at multiple distances.

Slight Residual Prescription: If your eye naturally has a tiny amount of residual myopia (nearsightedness) after surgery, it could enhance your ability to read up close while still maintaining clear distance vision.

Mini-Monovision Effect: In some cases, if your non-operated eye still has some nearsightedness or different vision characteristics, your brain may be combining the images from both eyes to create functional near and far vision.

Lens Positioning: The exact position where the IOL settles inside your eye can slightly affect its focusing ability. Sometimes, an IOL sits in a position that gives more range than expected."

Have a good evening...

*A little extra info on yesterday's painting of what I could see during the cataract operation - a friend sent me this...
"My doctorate was based upon vision and perception so this is fascinating and beautifully illustrated. The three types of cone cells in our eyes (S, (blue) M (green) and L (red)) are located in the macular region of the eye. With only these three colours our brains can construct several million different colours. S cone only activation gives blue. If the M and L cones are activated we get yellow, so there was lots of switching it seems and your brain was having a field day."
