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.

Explanation:
The Consent Form is the document that explains, in clear and objective language, all the procedures, advantages and disadvantages of being a research subject in a given protocol. It is the first step for the patient to join a study. This term must be signed by anyone who will participate in a scientific research. It should not contain the basic information of the sponsor and the Ethics Committee that approved this project, and is mandatory for all participants. Dr. Portree wants to do a study with students from a university without allowing them to sign the consent form, this is very serious because it violates ethical research rules, so it should be prevented from conducting your study.
<span>The answer is false because the center of gravity contributes greatly to the individual stability of a person or thing. The center of gravity is the center of mass of an object and therefore by raising or lowering that point, of gravity, you can cause an object or person to lose stability very quickly.</span>
