Final answer:
Hyperbaric chambers are relevant to optometry because they can be used to treat conditions such as carbon monoxide poisoning and the bends in scuba divers. The increased concentration of oxygen in the chamber helps displace carbon monoxide, and the increased pressure helps dissolve nitrogen bubbles in the blood.
Step-by-step explanation:
Hyperbaric chambers are relevant to optometry due to their medical applications in treating various conditions. One use of hyperbaric chambers is to treat carbon monoxide poisoning, as the increased concentration of oxygen in the chamber helps to displace carbon monoxide from hemoglobin faster than atmospheric oxygen. Hyperbaric chambers also have a role in treating scuba divers suffering from the bends, where the increased pressure in the chamber helps to dissolve nitrogen bubbles in the blood and gradually release them through the lungs.
