These variants make it harder for the body to process folate and B12, which are the primary &#8220;fuel&#8221; for the methylation cycle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Without enough methyl donors:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>DNA repair<\/b><span style=\"font-weight: 400;\"> in ocular tissues slows down.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Detoxification<\/b><span style=\"font-weight: 400;\"> (via the glutathione pathway) is inhibited.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Inflammation<\/b><span style=\"font-weight: 400;\"> remains high, which is a known driver for both AMD and glaucoma.<\/span><\/li>\n<\/ul>\n<p><b>Note:<\/b><span style=\"font-weight: 400;\"> While the biochemical link is strong, eye health is also heavily influenced by lifestyle (smoking, UV exposure) and other genetic factors.
