Peat Archive

Ray Peat discussed eye health in the context of his broader metabolic framework. He noted that the retina is one of the most metabolically active tissues in the body and is therefore highly sensitive to metabolic insufficiency. Cataracts, glaucoma, and macular degeneration, in his view, are manifestations of the same metabolic failure that causes other degenerative diseases.

Peat recommended protecting eye health through metabolic support (thyroid, adequate nutrition), reducing PUFAs (which accumulate in retinal tissue), and avoiding excessive UV exposure in the context of high PUFA intake. He also noted that progesterone protects against glaucoma by reducing intraocular pressure.
