8 Why do vision problems often appear before heart symptoms?

Large arteries handle stress longer than small vessels in the body
Eyesight conditions need more time to develop than chest pain
Heart and eye symptoms always appear together
Small eye vessels show damage from poor blood flow sooner
Tiny blood vessels in the eyes are affected by poor circulation before larger heart arteries show problems. Learn more.
