Gotta go get some lead poisoning on top of the depression…
Another visual effect in Van Gogh’s paintings is the halo swirling effect as seen in his painting, The Starry Night. It has been suggested that he may have suffered from lead poisoning, caused by the use of lead-based paints used at that time. One visual symptom of lead poisoning is the swelling of the retina, causing a halo effect around lights. Others have suggested that Van Gogh suffered from narrow angle glaucoma attacks which can also cause colored halos. Of course, cataracts cause halos around lights at night but since Van Gogh committed suicide at the early age of 37, it is unlikely that he had cataracts.
