Near sightedness is a condition whereby the eyeball is too long or cornea has excess curvature such that light entering the eye is focused in front of the retina rather on the retina itself.
The exact cause of nearsightedness is unknown but there are two factors that may be responsible for its development.
1. Visual stress
2. Heredity
Individuals who spend considerable time reading or working at a computer or engage in other types of intense close visual work may develop nearsightedness.
There is credible evidence that many people inherit nearsightedness or are at least predisposed to the condition, especially if both parents suffer from the condition.
Far sightedness (hyperopia) is a condition where the eye is shorter than normal, the cornea is not curved quite enough or the lens sits further back in the eye than is normal.
This condition can be inherited especially if both parents suffer from it.
The other cause is through diseases like diabetes or glaucoma.
Answer:
Administer supplemental oxygen
Explanation:
The first step in this case is to ensure that the patient's body contains the appropriate oxygen levels, so you should provide supplemental oxygen administration.
Oxygen is a basic necessity for all humans. The air we breathe contains 21% oxygen. The man who has been intoxicated has difficulty breathing, so we can conclude that his body is oxygen deficient, which can cause many problems including death. For this reason, the first step is to administer supplemental oxygen and then provide emergency medical care for this man.
Tar, carbon monoxide, nitrogen oxides, theyre harmful because they cling to the red cells in the blood and up to 15% of a smoker's blood may be carrying carbon monoxide round the body rather than oxygen.Smoking 'lower tar' cigarettes can increase the carbon monoxide levels as smokers inhale more deeply.Cigarette smoke has high levels of nitrogen oxide.
Hope that helps
