Answer 2

Answer:

Myopia

• It is also known as near - sightedness.
• A person with myopia can see nearby objects clearly but cannot see far objects clearly.
• It can be corrected by using concave lens.

                                                                                                                                                                       

Hypermetropia

• It is also known as far - sightedness.
• A person with hypermetropia can see far objects clearly but cannot see nearby objects clearly.
• It can be corrected by using convex lens

                                                                                                                                                                           

Presbyopia

• Due to ageing people are unable to see nearby and distinct objects , then the effect which is arrised is known as presbyopia.
• It can be corrected by bifocal lens
