When was Galileo blinded?

Answer 1

He became completely blind in 1638, at the age of 72, four years before his death in 1642. He became blind through natural causes. Some sources say it was cataracts/glaucoma, but I don't have a primary source for that. There's also a myth that he became blind from observing the sun through telescopes, but that seems very unlikely - his sunspot observations were conducted 25 years earlier, and always around sunset. If the sun observations were that damaging to his sight, it seems he wouldn't have been able to make any of his detailed and pioneering observations on sunspots.

Answer 2

at the age of 72 it was from combination cataracts and glaucoma.

Answer 3

Around June in 1637, he lost sight in his right eye. Then, in December 1637, he lost his vision completely.

Answer 4

No, that's folklore, he went blind from cataracts and glaucoma.

Answer 5

Galileo was not blinded. However, in his later years, he did suffer from poor eyesight due to cataracts, which eventually led to blindness before his death in 1642.
