A 35-year-old man with color blindness had improved color vision after consuming magic mushrooms. The case was reported by American psychiatrists from the Cleveland Clinic, and showed that the improvement was intense in the ability to distinguish the color green in the eight days that followed the consumption of the substance. The improvement persisted for more than 16 days.
The article was published in the magazine Drug Science, Policy and Law last Tuesday (2/5). He revealed that the use of fungi with psilocybin led the man to a 39% improvement in his performance in the Ishihara tests, which identify the ability to differentiate colors.
Color blindness is a vision difficulty linked to distinguishing colors, especially the ability to identify green and red. The condition, according to the Ministry of Health, affects about 5% of men and 0.5% of women with varying degrees of seriousness.

The study, however, found a barrier in the patient’s habits. He was supposed to consume only 5 g of the substance to assess the long-term impacts, but the man ended up mixing the mushroom with other drugs, which made it impossible to continue data collection.
“The improvement in the test could even last longer than the 16 days, but the use of additional substances prevented us from doing this analysis”, say the scientists.
Still, even a year and a half after using it, the man continued to score better on the tests than he had before he ate the mushrooms.
The researchers point out, however, that the use of psychedelic mushrooms is not a cure for color blindness, since the effects diminish without the substance and that the patient never got a perfect score on the test.
Even so, they state that it is important to highlight the significant improvement that the man experienced and that future tests can be done to determine if the use can be generalized and what is the ideal amount of the substance.
