Yes, Claude Monet had cataracts, and they profoundly changed both his vision and his art during the last fifteen years of his life. He was first diagnosed in 1912, at age 72, after consulting several ophthalmologists who recommended surgery on his worse eye. He refused for over a decade, and the progression of the disease left a visible trail across some of the most famous paintings in art history.
How His Vision Changed Over a Decade
Monet’s cataracts were the slowly progressive, age-related type known as nuclear sclerosis. In this condition, the lens of the eye gradually yellows and darkens, filtering out shorter wavelengths of light (blues and violets) while letting warmer tones through. The effect is like looking through an increasingly amber-tinted window.
When he was first diagnosed in 1912, Monet described only slightly reduced vision. His visual acuity at that point was likely no worse than 20/50, meaning he could still function well in daily life and continue painting. But by 1914 to 1915, the decline became serious. He wrote that “colors no longer had the same intensity,” that “reds appeared muddy,” pinks looked “insipid,” and his paintings were “getting more and more darkened.” The intermediate and lower tones, he said, escaped him entirely.
By 1922, the condition had worsened dramatically. Researchers who later simulated his vision found that images which would appear strikingly orange or strikingly blue to a normal eye were, to Monet, almost indistinguishable from one another: both collapsed into a murky yellow-green. He could still recognize the coarseness of his brushstrokes, but he could not see the true colors he was putting on canvas.
The Visible Shift in His Paintings
The progression of Monet’s cataracts is essentially documented in paint. His earlier Water Lilies and garden scenes from before 1914 are defined by delicate blues, greens, and soft atmospheric light. As his cataracts advanced, the palette shifted. Paintings from 1914 to 1917 show dulled, muted colors. Works from the early 1920s are dominated by heavy reds, oranges, and yellows applied in increasingly broad, coarse strokes.
This wasn’t an intentional stylistic evolution. Monet’s Impressionist approach relied on capturing light and color as he perceived them, and his cataracts were literally rewriting what he perceived. Even if he painted from memory or habit, he couldn’t judge the effect his colors had on a viewer, and any attempt to refine a painting risked making it worse. He knew this, and it tormented him. He reportedly destroyed a number of canvases he believed had been ruined by his failing eyesight.
Why He Resisted Surgery for So Long
Cataract surgery was well established and relatively safe by the 1910s, so Monet’s reluctance wasn’t about the risk of the procedure itself. His concern was specific and, for a painter, entirely logical: he feared the surgery would alter his color perception. The irony is that his color perception was already severely distorted by the cataracts. But Monet had built his entire artistic identity on how he saw color, and any change to that felt like a threat to his work.
He finally agreed to surgery in 1923, when his vision had deteriorated to the point where painting was nearly impossible. The operation removed the clouded lens from his right eye.
Life After Surgery
Removing the lens solved the yellowing problem but created a new one. Without a lens (a condition called aphakia), Monet’s eye could no longer filter ultraviolet light the way a normal eye does. The result was that by the summer of 1924, blue had replaced yellow as the dominant color in his vision. Everything took on a whitish-blue cast. He also had difficulty focusing at various distances, since the lens is responsible for adjusting focus.
Monet was eventually fitted with corrective glasses that helped compensate for these issues. Once his vision stabilized, the change in his painting was striking. His postoperative works returned to the delicate color schemes of his earlier career, with gentle blues and greens replacing the garish warm tones that had dominated his cataract-era canvases. The coarse brushwork softened. Side by side, the pre-cataract and post-surgery paintings look like they were made by the same artist; the paintings from the worst years of his cataracts look like the work of someone else entirely.
What His Story Reveals About Cataracts
Monet’s experience is one of the most thoroughly documented cases of how cataracts affect color perception. Most people with early cataracts notice that colors seem faded or slightly yellowed, but the change is so gradual that the brain compensates, and many people don’t realize how much their color vision has shifted until after surgery restores it. Monet, whose livelihood depended on precise color perception, noticed earlier and more acutely than most.
The specific type he had, nuclear sclerosis, remains the most common form of age-related cataract today. It produces exactly the kind of progressive yellowing and darkening Monet described. His paintings from 1912 to 1923 serve as a remarkably accurate visual record of what this type of cataract does to the world as you see it: first muting colors, then shifting everything toward amber, and finally collapsing distinct hues into an undifferentiated warm murk.
