As such some of what we see is just the brains interpretation of sensations from the eye structure and the pressure applied to it. Try rubbing your closed eyes and you will see what I mean. Always remember that the number one job of the brain is pattern recognition.
Emphysema is a form of chronic (long-term) lung disease, usually caused by smoking. Because of lung damage, people with emphysema have difficulty blowing air out. The major symptom of emphysema is shortness of breath.

Emphysema is among a group of lung diseases known as COPD, in which the alveoli of the lungs become damaged, causing them to enlarge and burst.

This causes a build-up of carbon dioxide in the body.
