Eye related diseases are related to blood vessel changes

The vision-robbing diseases of the eyes that come with age (glaucoma, macular degeneration, diabetic retinopathy, etc.) are all, in a way, related to the depletion of the nutrients the blood carries to the blood vessels of the eye, as well as the deterioration of the vessels themselves. The overall effect can be damage to the retina and optic nerve. When it comes to protecting from this damage a healthy lifestyle and yearly eye exams is the best offense to what can be devastating circumstances.
