Question

What is myopia?

Answer 1

Myopia: 

• It is an eye disease which may occur to any person at any age. 
• The person is unable to see distant objects clearly. 
• It is caused either due to increased focal power of the lens (lens become more convex) or eyeball becomes larger. 
• It is also called a short-sightedness. 
• It can be corrected by use of biconcave lenses, which are also called as “minus lenses”.
