-BARSIC- [3]3 years ago

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.

In ethics does clothes matter or pure aesthetic taste, make sense to become a subject?<br><br><br>​
matrenka [14]

Answer:

Clothes are one of the fundamental necessities of human beings like food and shelter to protect themself from cold, rain, and other environmental conditions. Clothes nowadays become a status symbol and form of expression.

Clothes should not be a subject of ethics as it is their personal choice and clothes also use as a form of art. One should not defy or judge a person by his or her clothes as it a personal choice and environmental necessities.

However, in some cases like school, workplace, there are obligations to follow the dress code, it is a form of ethics but it is to show professionalism and equality among all students and employees.
