Quora is an interesting website where people can ask any type of question that is occupying their minds.  Questions will inevitably be answered by a professional or another person who might not have professional experience but is still offering advice based on experience and education.  I have enjoyed answering science questions along with random relationship questions too.



There are questions which I choose not to answer.  Especially if the previous answer is sufficient or better than the answer I may provide.  Below is one such example question which was posted on Quora.

"Which light is harmful for eyes?"

An example of a question which I was requested to answer was the following: "Which light is harmful for eyes?"   The answer is shown below.

The source of light is not relevant; it is the quantity of light that matters. Extremely intense light from a welding flash, or from the sun is harmful.

However it is important to recognize the often confused difference between HURT and HARM. There are many activities which will tire your eyes and make them hurt, but HARM is when permanent damage occurs. This is really only as described above.

The person who provided the answer above was a professional ophthalmologist (eye doctor).  Instead of answering the question, I chose to learn from the other answers provided.  Which is interesting since I do not have to answer every question asked of me.  On the flip side, I can learn from the question and answer.  I love learning.



Quora is a great website to learn from.  At the very least, the question and answers provided are a great opportunity to start a journey toward learning a greater amount about a given subject.  Simply by reading the question and answer might spark a learning journey that was previously not thought possible.  Enjoy and keep learning while asking questions about life.
