Glaucoma is a type of eye disease that damages the optic nerve, which carries visual information entering the eye to the brain.
The most usual cause of glaucoma is due to an increase in pressure inside the eye (ocular hypertension), which diminishes the blood supply that provides vital oxygen and nutrients to the optic nerve.
Lazy eye, or in medical terminology: amblyopia, happens when vision in one eye isn’t as sharp as it should be at a certain stage in a person’s development.
Lazy eye is typically noticed in infancy and early childhood, where the condition manifests as one eye having reduced visual acuity compared to the other. In some cases, both eyes can fail to develop normal visual acuity.
